POP3 Protocol Explained: History, Usage, Advantages, and Disadvantages

What is POP3 Protocol?

POP3 stands for Post Office Protocol version 3. It is one of the oldest and most widely used email protocols that allows users to retrieve emails from a remote server to their local device. Once the email is downloaded, it is typically deleted from the server (although modern clients may offer to leave a copy).

POP3 was designed with the idea that users would connect to their mail server, download all the emails, and then disconnect. This made it ideal for dial-up connections or limited internet access back in the early days of the internet.

---

History of POP3

The original Post Office Protocol (POP1) was developed in 1984 by the Internet Engineering Task Force (IETF) to enable simple mail access. It was followed by POP2 in 1985 with minor improvements.

The version we use today, POP3, was defined in RFC 1081 (1988) and later updated in RFC 1939 (1996). Over the years, it became a standard due to its simplicity and reliability.

Despite its age, POP3 is still supported by most mail servers and email clients, including Outlook, Thunderbird, and Apple Mail.

---

How POP3 Works

Here's a basic workflow of how POP3 functions:

1. You open your email client (like Outlook).

2. It connects to your email server using POP3 (typically port 110 or 995 for SSL).

3. The client downloads all your new messages from the server.

4. The messages are stored locally, and by default, they are deleted from the server.

5. You can then read, reply, or manage your emails offline.

It’s a one-way communication, from the server to your device.

---

Usage of POP3

POP3 is used in:

• Personal email setups where internet access is limited or expensive.

• Backup email clients where storing mail offline is preferred.

• Cases where you need simple email access without synchronization across devices.

---

Advantages of POP3

Here are some reasons why POP3 is still in use:

1. Offline Access: Once downloaded, emails can be accessed without an internet connection.

2. Less Server Storage: Since emails are removed from the server, it saves server space.

3. Speed: Downloaded messages open instantly as they are stored locally.

4. Simplicity: Easy to implement and configure.

5. Privacy: Your emails are on your local device only.

---

Disadvantages of POP3

Despite its benefits, POP3 comes with several limitations:

1. No Sync Across Devices: POP3 doesn’t support syncing, so reading an email on your phone won’t mark it read on your computer.

2. Emails Can Be Lost: If your device crashes and you haven’t backed up, the emails are gone.

3. No Folder Support: You can’t organize emails into folders on the server like you can with IMAP.

4. Limited Functionality: No access to server-side search, flags, or labels.

5. Outdated for Modern Use: Doesn’t suit today’s multi-device, always-connected world.

---

Is POP3 Still Relevant Today?

POP3 still holds relevance in specific contexts:

• Low-bandwidth or rural areas

• Legacy systems

• Users preferring local storage

• For archiving old accounts

However, most modern users and businesses prefer IMAP or cloud-based solutions like Gmail, Outlook 365, or Zoho Mail, which offer cross-device access and robust features.

---

Final Thoughts

While POP3 is a veteran of the email world, its limitations make it less suitable for today’s always-connected, multi-device environments. However, it’s still a simple and effective protocol for basic needs or specific use cases.

If you are managing an email campaign or sending emails from your website or application, make sure your emails are not landing in spam folders. One way to ensure that is by checking your email’s spam score.

Gmail Unsubscribe Scam: Why Clicking "Unsubscribe" Might Be a Trap

Before you hit "unsubscribe" on that annoying email—pause. That one click might cost more than you think.

With our inboxes brimming over with promotional offers, survey requests, fake job alerts, and never-ending webinar invites, the unsubscribe link often feels like a beacon of relief. But cybersecurity experts caution that clicking it blindly can actually put your personal data at serious risk.

A recent report by The Wall Street Journal sheds light on this growing threat. What seems like a harmless action—opting out of unwanted emails—can serve as a beacon to cybercriminals, signaling that your email address is active and ready to be exploited.

What Is the Gmail Unsubscribe Scam?

Here’s how this clever scheme unfolds: Cybercriminals send mass emails that resemble ordinary marketing newsletters. Hidden within are unsubscribe links that don't actually remove you from a list. Instead, they perform a much more dangerous function.

By clicking that link, you might be redirected to a phishing page designed to harvest your personal data. Some pages will ask you to "confirm your subscription preferences" by entering login credentials, passwords, or other sensitive details. Others silently log your click as confirmation that your email is being monitored—making you a prime target for future attacks.

DNSFilter data cited by The Wall Street Journal revealed a sobering fact: approximately 1 in every 644 unsubscribe links leads to a malicious site.

Smarter Ways to Clean Up Your Inbox (Without Risk)

If you're tired of the clutter, you're not alone. But there are much safer strategies to keep your inbox under control:

1. Use the Native “Unsubscribe” Feature in Your Email App

Platforms like Gmail and Outlook often display a verified unsubscribe option at the top of promotional emails. These are backed by a system called “list-unsubscribe,” which communicates directly with legitimate senders—without redirecting you to external websites.

2. Mark Suspicious Emails as Spam

Instead of clicking a shady-looking unsubscribe button, mark the message as spam or junk. This action not only removes the message but also helps your email provider learn and block similar messages in the future.

3. Never Interact With Emails From Unknown Senders

If you don’t recognize the sender or if the message feels off, don’t click anything—not even the unsubscribe link. Just delete the message or report it as spam.

4. Use Privacy Tools Like "Hide My Email"

Services like Apple’s Hide My Email, or browser add-ons like DuckDuckGo’s Email Protection, allow you to create disposable email addresses. These tools act as a privacy buffer, keeping your real address safe from trackers and malicious campaigns.

5. Keep Your Email Client and Security Tools Updated

Hackers continuously evolve their tactics. To stay a step ahead, make sure you regularly update your email apps, browser extensions, antivirus software, and operating system. Updates often include patches for known vulnerabilities.

---

Final Thoughts: Caution Over Convenience

While it might feel like you're just tidying up your inbox, clicking that unsubscribe link could do more harm than good. In today’s digital age, even the most innocent actions can have hidden consequences. Let your email platform do the heavy lifting—use its built-in tools to unsubscribe safely, and steer clear of anything suspicious.

Remember: When it comes to email security, it’s better to be overly cautious than to become another statistic.

AI Mode in Google Search Console: What You Need to Know

Google’s integration of AI into Search has significantly shifted how users interact with information—and how marketers track performance. With the recent U.S. rollout of AI Mode to all users, SEO professionals and advertisers are watching closely to understand how this change will affect reporting and visibility. But while Google Search Console will soon report AI Mode performance data, there's a big catch: you won’t be able to break it out.

In this blog, we’ll break down what’s changing, what you can expect in Search Console, and why this matters for your SEO and paid marketing strategies.

---

📌 What Is AI Mode?

AI Mode is part of Google's broader AI integration into Search, alongside features like AI Overviews. It provides summarized answers to user queries powered by generative AI, aiming to speed up information discovery.

Initially launched through Google’s Search Labs in March 2024, AI Mode is now available to all users in the U.S. As it rolls out globally, it is expected to become a core part of how Google delivers search results.

---

🔍 Will Google Search Console Track AI Mode?

Yes—but not how you’d expect.

Google has confirmed that AI Mode data will be included in Search Console’s Performance report, specifically under the “Web” search type. This means that any clicks or impressions generated via AI Mode will be lumped together with your regular web search traffic.

However, here’s the crucial part:
🔒 There’s no way to break out AI Mode traffic from the rest of your search performance data.

This lack of segmentation means you won’t know:

• How much traffic came specifically from AI Mode.

• Which queries or pages performed well in AI Mode.

• Whether your content was surfaced in the AI snapshot or not.

---

📉 Why Can’t You Break It Out?

Google spokesperson John Mueller confirmed on LinkedIn that AI Mode reporting will be included in Search Console, but without detailed segmentation:

“There’s currently no separate break-out planned, and no API change involved.”

He emphasized that while the data will be visible, it won’t be possible to isolate AI Mode traffic or analyze it independently.

Google’s updated documentation supports this, stating:

“Sites appearing in AI features (such as AI Overviews and AI Mode) are included in the overall search traffic in Search Console.”

So, for now, AI Mode is just another part of your total web search traffic—invisible but impactful.

---

🐞 What About the Tracking Bug?

Early on, there was a bug that made AI Mode traffic completely untrackable. Although that’s now being addressed, tracking remains murky. Until Search Console updates go live and more clarity is provided, marketers will have to navigate this gray area without clear data.

---

🎯 What About Ads in AI Mode?

Even though Google is now testing ads within AI Mode and has already integrated them into AI Overviews, advertisers are facing the same issue:
You can’t track AI Mode ad performance separately.

This is a major concern for advertisers who rely on detailed attribution and optimization metrics. Google’s promises of “control and transparency” during its Marketing Live events feel increasingly hollow when marketers have no way to see how ads perform in emerging search environments.

---

📣 Why This Matters for Marketers

AI Mode is poised to reshape how users discover and engage with content. But the inability to view its performance data separately means:

• You can’t tell if AI Mode is boosting or harming your traffic.

• There’s no way to optimize specifically for AI-generated answers.

• Paid campaigns may show impressions and clicks with no visibility into whether AI surfaces were involved.

This limits your ability to make informed decisions and adapt your strategies to this new search behavior.

---

📢 What Can We Do?

For now, marketers and SEOs can:

• Monitor overall performance trends closely to spot unexplained changes that might be tied to AI Mode.

• Continue to optimize for helpful, concise, and structured content, which AI systems are more likely to reference.

• Stay vocal. The SEO and ad community is pushing Google to introduce segmented AI Mode reporting in both organic and paid dashboards.

As many experts have noted, transparency is crucial for maintaining trust and effectiveness in digital marketing. Without visibility, brands are operating in the dark.

---

🧭 Final Thoughts

AI Mode may represent the future of Google Search, but that future is arriving with significant limitations for those who create, measure, and monetize online content. While it’s encouraging that Google is working to integrate AI Mode data into Search Console, the lack of visibility into what that data really means is a major hurdle.

If you're serious about understanding your performance in this new AI-driven landscape, stay updated—and keep pushing for more transparency. Because if AI Mode is going to define the next chapter of search, we need the tools to understand it.

🚨 Spam Alert! How Small Businesses Can Outsmart Email Scams

Let’s get one thing straight — we’re not cybersecurity pros.

We’re a small business, just like you, trying to make our way through the digital world without falling into a scammer’s trap.

Over time, we’ve learned a few practical tricks to keep our inboxes clean and our data safe. This isn’t high-level tech advice — just the tried-and-true tips we’ve picked up along the way that really work.

🔥 Simple Tips to Spot (and Stop) Email Scams

1. Double-Check the Sender’s Email Address

Scammers are sneaky. They’ll mimic big-name companies using email addresses that look real at first glance — but they’re just clever fakes.
Pro Tip: Always hover over or tap on the sender’s name to check the full email address. If something looks off, trust your gut.

2. Watch Out for Urgent Language

Emails that yell “Immediate action required!” or “Your account will be suspended!” are waving giant red flags.
Legitimate companies don’t pressure you into making snap decisions — especially not without proper context or warning.

3. Think Before You Click

If a link seems suspicious or looks unfamiliar, don’t click it.
Hover over it to see where it actually leads — and when in doubt, go directly to the official website instead of following email shortcuts.

4. Be Skeptical of Generic Greetings

Scam emails often start with vague intros like “Dear user” or “Hello there.”
Real businesses that know you will use your actual name or company name.

5. Never Share Sensitive Info Over Email

This one’s non-negotiable: Never email passwords, financial details, tax info, or login credentials.
No reputable company will ask for this kind of information over email. Ever.

6. Use Two-Factor Authentication (2FA)

Enable 2FA on your email, social media, and business tools.
It’s one extra step that makes it much harder for scammers to get in — even if they somehow get your password.

7. Make Email Safety a Team Priority

Scammers love to catch people off guard. Talk to your team regularly about email safety.
All it takes is one accidental click to cause a major headache.

---

Why This Matters — Especially for Small Businesses

Unlike large corporations, we don’t have massive IT departments watching our backs.
We are our IT department — which means we have to stay extra alert.

Email scams can lead to:

• Financial loss

• Compromised accounts

• Customer data breaches

• Days (or even weeks) of stressful recovery

But here’s the upside:
Most scam emails follow predictable patterns. Once you know what to watch out for, dodging them becomes a whole lot easier.

---

✅ The “Uh-oh” Checklist — What to Do When You’re Suspicious

• Don’t click on any links

• Don’t download attachments

• Mark it as spam or phishing

• Delete it immediately

• Contact the sender through a verified channel if you’re unsure

We’re not tech experts — just fellow entrepreneurs trying to stay smart and secure in a digital world full of traps.
Hopefully, these tips give you a little more confidence (and peace of mind) the next time you’re sorting through your inbox.

Stay safe out there!

Gmail's Big AI Upgrade: Why You Might Need a New Email Address

With over 2 billion users, Gmail is a household name. But Google’s latest AI-powered upgrade is shaking things up—and it’s raising some big questions about privacy. If you're a Gmail user, it's time to pay attention.

Gemini Is Here—And It Knows Your Emails

Last week, Google introduced an update that integrates its Gemini AI with Gmail, allowing it to draft personalized replies that mimic your usual writing tone. How does it do that? By learning from your previous emails and Google Drive files—if you give it permission.

“Draft replies will sound authentically like you,” Google said. “They’ll match your tone and context.”

That sounds convenient, but here’s the catch: while AI integration could save time, we’re still in the early stages of understanding the privacy and security risks this creates. There’s also a contradiction here—Google recently strengthened Gmail's encryption, which doesn’t exactly mesh with this new AI digging through your messages.

What Gmail Really Needs: Privacy, Not Just AI

Apple users already have a great privacy tool called Hide My Email. It lets you generate unique, anonymous email addresses for things like signing up for newsletters or shopping online—keeping your real address private.

This isn’t just about spam control (which AI hasn’t fully solved anyway); it’s about data breaches. As one writer from How-To Geek put it, “I seem to get emails almost every week telling me my account info was exposed.” That’s why using tools like Hide My Email is more important than ever.

Google’s Answer: Shielded Email for Android

For Android users, there’s good news. Google has been working on a similar tool called Shielded Email, first spotted in November and later confirmed by Android Authority.

Shielded Email will integrate with Google’s Autofill system, so when you’re signing up for something, Gboard might suggest a temporary email address to protect your real one. While the feature isn’t live yet, it's reportedly in late-stage development.

This kind of feature is more than just handy—it’s necessary. With massive breaches like the one discovered by vpnMentor exposing 184 million usernames and passwords, the threat is real. Many of those exposed files included logins to banks, healthcare providers, and government portals.

Shielded Email can make it harder for hackers to track you across websites. If an email gets compromised, you can simply disable it—no need to change your primary address. Pair this with strong passwords, two-factor authentication (2FA), or better yet, passkeys, and your accounts will be much more secure.

Email: The Ultimate Identity Crisis

Your email address is often your digital identity. That makes it a target. If your main address is leaked or tracked, you’re vulnerable. If you can mask it, you’re one step ahead.

And that’s why you might want to consider starting fresh. Get a new email address—especially once Shielded Email is available—and slowly transition your accounts over. It’s like decluttering your digital life and protecting your future self at the same time.

The Privacy vs. Convenience Dilemma

According to a survey by Android Authority, 73% of Gmail users said they’d switch to Proton Mail, a service known for its privacy-first approach. Over half said they’d even pay for it. Only 27% felt satisfied with Gmail’s current privacy stance.

This aligns with growing concerns after Google announced Gemini AI would now have access to users’ entire Gmail history and Google Drive. While Google promises not to use this data for ads or training its AI models (at least within Workspace), some users aren’t convinced.

“I gave Gemini access to my Gmail, and it weirds me out,” one PCMag reviewer wrote. Despite Google’s reassurances, trust is clearly wavering.

What’s Next?

Email is evolving, but not everyone is comfortable with where it’s going. As AI becomes more embedded in our inboxes, we need better privacy protections. Shielded Email is a step in the right direction, but until it rolls out fully, it’s worth thinking carefully about your current email setup.

Ask yourself: Is it time to make a change? Opening a new email account and using tools that protect your identity might be the smartest move you can make today.

How Hackers Are Exploiting Email Input Fields: From XSS to SSRF

In recent months, cybersecurity researchers have observed a troubling rise in attacks targeting a rather innocent-looking component of most websites: email input fields. These seemingly harmless form fields—used everywhere from sign-up pages to password reset forms—are being weaponized by attackers to exploit serious vulnerabilities, including Cross-Site Scripting (XSS), Server-Side Request Forgery (SSRF), and email header injection.

While email fields are ubiquitous in modern web applications, their widespread use and the flexibility in email formatting make them a common weak point. If input handling isn't airtight, hackers can slip in malicious payloads that wreak havoc on users and backend systems alike.

---

XSS Attacks via Email Fields

Cross-Site Scripting (XSS) happens when attackers inject malicious JavaScript into a web page, and the script runs in the browser of unsuspecting users. This becomes especially dangerous when applications reflect user input—like email addresses—into web content without proper sanitization.

According to cybersecurity researcher coffinxp, threat actors are crafting email addresses containing JavaScript payloads and submitting them through forms. For instance:

html

<script>alert('XSS')</script>@example.com

If this input is rendered in an HTML email or a confirmation page without escaping or sanitization, the script executes. This can lead to cookie theft, session hijacking, or even defacement of the website.

---

SSRF Through Email Validation

Another emerging vector is SSRF, or Server-Side Request Forgery. Some applications validate email addresses by querying DNS records or fetching avatars (like from Gravatar) using server-side requests.

Attackers can exploit this by submitting email addresses such as:

bash

test@127.0.0.1
test@169.254.169.254

If the server doesn't filter outbound requests carefully, it may inadvertently query internal services or cloud metadata endpoints—potentially exposing sensitive internal data or AWS credentials.

---

Email Header Injection: A Lesser-Known But Dangerous Threat

When user input is directly inserted into email headers (e.g., in contact forms or user notifications), header injection becomes a real risk. By injecting newline characters (%0d%0a or \r\n), attackers can manipulate the structure of outgoing emails.

For example:

perl

attacker@example.com%0d%0aBCC: victim@example.com

This could result in unauthorized recipients being added (CC/BCC), spoofed email content, or even spam and phishing campaigns originating from your application.

---

How to Mitigate These Threats

Security starts with treating all user input as untrusted—especially something as seemingly benign as an email address. Here's how to defend against these risks:

✅ 1. Use Strict Validation

Validate email addresses using well-tested libraries that comply with RFC 822 or RFC 5322 standards. Avoid rolling out your own regex.

In Python:

python

import re
email_regex = re.compile(r"^[^@]+@[^@]+\.[^@]+$")

✅ 2. Sanitize Inputs

Never insert raw input into HTML, JavaScript, or email headers. Use context-aware escaping functions to avoid injection issues.

✅ 3. Block CRLF Characters

Filter or encode newline characters to prevent header injection. In PHP, for example:

php

$email = str_replace(array("\r", "\n", "%0a", "%0d"), '', $email);

✅ 4. Control Server-Side Requests

Limit where your application can make outbound requests. Block internal IP ranges like 127.0.0.1, 169.254.0.0/16, and other private networks.

---

It Doesn't End There...

While XSS, SSRF, and header injection are among the most common email field exploits, attackers don’t stop there. Email inputs can also be a foothold for:

• SQL injection

• Command injection

• Open redirects

• Business logic abuse

• Unicode spoofing & homograph attacks

The list keeps growing as cybercriminals get more sophisticated.

---

Final Thoughts

The humble email input field might not seem like a major threat vector—but in the wrong hands, it’s a goldmine for attackers. Developers must stay proactive by implementing strong validation, sanitization routines, and security best practices at every step of input handling.

Regular vulnerability assessments, penetration testing, and the adoption of secure coding practices are essential to prevent your application from becoming the next breach headline.

Protect Your Inbox: Smart Ways to Stay Ahead of Cyberattacks

Cyberattacks are on the rise—especially across the Asia-Pacific (APAC) region—and small and medium-sized businesses (SMBs) are increasingly becoming targets. The Cyber Security Agency of Singapore (CSA) has recently raised red flags about the growing number of AI-driven phishing attacks, and sectors like retail are among the most vulnerable.

Why Email Is a Prime Target

Email is still the backbone of business communication. But with its convenience comes vulnerability. Cybercriminals know how much trust we place in our inboxes, and they’re exploiting that trust—especially in businesses that may not have a dedicated cybersecurity team.

SMBs often don’t have the same resources as larger enterprises, making them an easier mark. And once a hacker gets in, the damage can be devastating.

The Most Common Email Threats You Should Know

Phishing remains one of the top threats. These scams often appear as emails from trusted sources—like a boss or business partner—asking for sensitive info or financial transfers. Because they look legitimate, they’re surprisingly effective.

Credential theft is another growing concern. Attackers send emails with fake login pages, tricking users into handing over their usernames and passwords. Once inside, hackers can infiltrate internal systems and cause serious damage.

Ransomware is also making headlines. According to IDC, nearly 60% of companies in the APAC region were hit by ransomware attacks this year. These attacks usually start with an innocent-looking email attachment or link and can end with files being encrypted and held for ransom.

5 Smart Strategies to Keep Your Email Safe

If you're looking to outsmart cybercriminals, here are five proactive steps you can take:

1. Use Advanced Spam Filters
   Invest in spam filters that use machine learning to catch suspicious emails before they land in your inbox.

2. Set Up Email Authentication
   Protocols like SPF, DKIM, and DMARC help verify that incoming messages are legit, reducing the risk of spoofing.

3. Train Your Team
   Regular training helps employees spot phishing attempts and know what to do when they see something fishy.

4. Do Routine Security Audits
   Periodically review your email security setup to find and fix any weak spots.

5. Enforce Strong Passwords and MFA
   Require employees to use complex passwords and set up multi-factor authentication (MFA). Even if a password is stolen, MFA adds an extra layer of protection.

Prevention Is the Best Protection

Cyber threats aren’t going away. If anything, they’re getting more sophisticated. That’s why businesses need to stay one step ahead with a prevention-first approach. Combining smart technology with ongoing employee education can make a big difference.

Just one email breach can cause a cascade of problems—loss of data, financial damage, and serious hits to your reputation. Especially in industries like retail, where customer trust is everything, email security can’t be taken lightly.

Don’t Forget to Check Your Spam Score

Before sending your next email campaign, make sure it's not ending up in the spam folder. Use TestMailScore.com to check your email’s spam score for free. It gives you deep insights into how your email is performing and how to improve deliverability.

Microsoft Tightens the Reins on Outlook.com Bulk Email Senders

In a decisive move to combat spam and protect user inboxes, Microsoft is implementing stricter rules for high-volume email senders using its Outlook.com service.

With over 160 billion spam emails flooding the internet daily, email spam remains a persistent challenge for users and service providers alike. Outlook.com, being one of the most widely used email platforms, is now stepping up its efforts to crack down on unsolicited and potentially harmful emails.

In a recent update published on the Microsoft Defender for Office 365 blog, the tech giant announced a set of new requirements targeting domains that send more than 5,000 emails per day. This initiative is part of Microsoft's ongoing mission to protect user trust and uphold email integrity.

"Outlook is stepping up its commitment to protect inboxes and preserve trust in the digital ecosystem," Microsoft stated in the blog.

What’s Changing?

Starting May 5th, Microsoft will begin enforcing new email authentication protocols. High-volume senders must now comply with three essential standards:

• SPF (Sender Policy Framework)

• DKIM (DomainKeys Identified Mail)

• DMARC (Domain-based Message Authentication, Reporting & Conformance)

These protocols work together to verify that emails are actually coming from the domains they claim to be sent from. By doing so, they help reduce spoofing, phishing attacks, and general spam, while also improving deliverability for legitimate senders.

Microsoft emphasizes that businesses and senders should act quickly:

"We encourage all senders, especially those operating at high volume, to review and update their SPF, DKIM, and DMARC settings to meet the new requirements."

What Happens If You Don’t Comply?

Emails failing to meet the required authentication standards will be rejected outright. The error message accompanying such rejections will read:
“550; 5.7.515 Access denied, sending domain [SendingDomain] does not meet the required authentication level.”

This change not only improves clarity for recipients but also gives senders a clear understanding of why their messages aren't being delivered, eliminating confusion around messages landing in the spam or junk folder.

A Welcome Move in the Fight Against Spam

This is a positive and necessary step toward making the digital communication landscape safer. By pushing for authentication standards like SPF, DKIM, and DMARC, Microsoft is helping ensure that Outlook users—whether individuals or small businesses—can trust the emails they receive.

How to Spot Microsoft Account Hacks Linked to WhatsApp and Signal Scams

If you use a Microsoft 365 account, you might want to be extra cautious. Reports have surfaced that hackers are targeting Microsoft accounts through popular messaging platforms like WhatsApp and Signal.

According to a report from Bleeping Computer, cybercriminals, allegedly linked to Russian threat groups, are impersonating officials from European countries to trick their victims into handing over sensitive login information. These hackers appear to have targeted individuals working at organizations related to human rights and Ukraine.

The goal of the scam is simple: the attackers are trying to convince victims to share Microsoft authorization codes, which grant them full access to the accounts. Alternatively, they may try to lure individuals into clicking on malicious links designed to steal login credentials and one-time access codes.

How to Spot These Scams

If you're worried about falling victim to this kind of attack, the cybersecurity company Volexity, which has been tracking these incidents since March, has shared valuable insights. In their blog post, Volexity highlights how these scammers reach out to their targets via Signal, WhatsApp, and even a compromised Ukrainian government email. They typically try to convince recipients to click on links that supposedly lead to a meeting about Ukraine-related topics.

Volexity even shared screenshots of the suspicious messages, which are worth checking out if you want to know what to watch out for. These messages should immediately raise a red flag—if you see something similar, be cautious.

As always, never click on any suspicious links, especially if you're part of an organization focused on human rights or geopolitical issues. Stay vigilant and protect your accounts!

Google’s Gmail Upgrade: The Good, The Bad, and What It Means for 3 Billion Users

Google is rolling out its next big AI upgrade for Gmail, and while it comes with exciting advancements, it also raises serious privacy concerns. On top of that, a long-hidden cyber threat has finally come to light—one that could put billions of users at risk.

The Good News: Stricter Spam Filters Are Working

Let’s start with the positive. Google’s stricter spam email policies are making a noticeable impact, significantly cutting down the number of unwanted marketing emails flooding inboxes. According to MarTech, email engagement rates—such as open and click rates—have dropped considerably, and most marketing emails now end up in spam unless recipients actively engage with them.

For businesses, this is a nightmare. Many brands are facing major challenges in reaching their audiences, even when following best practices. But for regular users, this is a welcome change—fewer annoying promotional emails and a cleaner inbox.

However, marketers are already working on ways to bypass these restrictions. MarTech notes that email deliverability is more of an art than a science, and businesses are actively testing new strategies to avoid spam filters. In other words, this battle is far from over.

The Privacy Trade-Off: AI Reads Your Emails?

While Google’s AI-powered enhancements aim to improve the user experience, they come at a cost. Many users are uncomfortable with the idea of AI analyzing their personal emails. Despite Google’s assurances that users have control over their data and privacy settings, the thought of AI reading emails has left many feeling uneasy.

Google insists that privacy remains a top priority, and users can manage AI-powered features in their settings. But with Gmail dominating the email market in the U.S., these changes affect a vast number of people—whether they like it or not.

The Bad News: A Sophisticated Email Attack Has Been Hiding for Years

While Gmail’s security improvements are making an impact, cybercriminals continue to evolve their tactics. Security researchers at Infoblox have uncovered a highly sophisticated phishing attack that has been operating undetected for years. This attack uses a DNS trick to serve fake login pages for over 100 brands, including Gmail, Outlook, Yahoo, DHL, and even major banks.

The technique, dubbed “Morphing Meerkat” by Bleeping Computer, leverages DNS mail exchange (MX) records to dynamically generate phishing pages that appear legitimate. Attackers then use compromised WordPress sites, URL shorteners, and adtech infrastructure to distribute phishing links. What’s worse, after stealing a user’s credentials, the attack redirects them to the actual login page, making them think they simply mistyped their password.

How to Stay Safe

This attack highlights a growing issue: passwords alone are no longer enough to secure accounts. While two-factor authentication (2FA) adds an extra layer of protection, some forms of 2FA can still be exploited. Google recommends enabling passkeys and using the strongest available authentication methods to protect your account.

Cybercriminals are also leveraging open redirects in Google’s DoubleClick ad network to disguise phishing links. Stolen credentials are then distributed through various channels, including Telegram. The fact that this operation remained hidden for so long shows just how sophisticated modern cyber threats have become.

The Bottom Line

Email security is improving, but so are cybercriminal tactics. Google's AI-powered Gmail updates come with both benefits and risks—better spam protection but potential privacy concerns. Meanwhile, a stealthy phishing attack serves as a reminder that users must stay vigilant.

To stay safe, avoid clicking on suspicious links, enable the strongest security measures on your accounts, and remember: when it comes to cybersecurity, caution is always better than regret.

3 Costly Omnichannel Marketing Mistakes Nonprofits Must Avoid

Many nonprofits struggle to bridge the gap between digital and direct mail marketing. Without a seamless omnichannel strategy, fundraising efforts can fall short. Digital channels like email, social media, and text messaging offer quick, direct ways to engage donors, while direct mail remains a trusted tool for building relationships and driving contributions.

But when these channels operate independently, nonprofits miss out on opportunities to foster long-term donor relationships. The key to overcoming these challenges? Data. A well-integrated approach can maximize fundraising success. To stay on track, nonprofits should avoid these three common omnichannel marketing mistakes.

1. Treating Online and Offline Donor Campaigns as Separate Initiatives

Many nonprofits run their digital and direct mail campaigns separately, often managed by different teams. This lack of coordination results in inconsistent messaging, redundant outreach, and a disjointed donor experience.

To fix this, organizations should integrate all touchpoints into a single donor journey. When online and offline efforts work together, campaigns become more cohesive and effective.

If donors receive conflicting messages or overwhelming appeals, they might disengage. The solution? Synchronize messaging across all channels—email, social media, direct mail, and text—to create a unified and engaging experience.

How to Make It Work:

• Leverage technology. Use QR codes or personalized URLs to seamlessly connect physical mail with digital platforms.

• Ensure consistency. Maintain a uniform tone, branding, and call-to-action across all channels to reinforce your mission.

By aligning digital and direct mail strategies, nonprofits can increase engagement, reduce confusion, and drive higher donations.

2. Overlooking Personalization, Segmentation, and Timing

Some nonprofits take a one-size-fits-all approach to save time and resources. Unfortunately, this often backfires, leading to disengagement. Donors interact in different ways—some prefer traditional mail, while others respond better to email or text messages.

To boost engagement, nonprofits must use data to personalize messages and segment donor lists based on preferences, donation history, and past interactions. Generic, mass communications fail to create meaningful connections, resulting in lower response rates.

Personalization goes beyond just using a donor’s name—it’s about delivering the right message, at the right time, through the right channel.

How to Make It Work:

• Segment and tailor communications. Create customized messages based on giving history and engagement levels.

• Time outreach strategically. Use data to identify the best times to connect with donors, such as sending reminders to past year-end donors at key moments in the giving cycle.

By personalizing outreach efforts, nonprofits can strengthen relationships and inspire greater donor commitment.

3. Ignoring A/B Testing and Failing to Measure Results

Successful marketing isn’t static—it requires continuous learning and optimization. A/B testing is crucial for understanding what works best, from subject lines and visuals to donation page layouts and call-to-action phrasing.

Without testing, nonprofits risk missing opportunities to fine-tune their messaging and improve engagement.

During campaigns, nonprofits should experiment with different elements—such as email subject lines, donation page designs, and sending times. A/B testing reveals what resonates most with donors, allowing for real-time strategy adjustments. Post-campaign analysis is equally essential to measure success and identify areas for improvement.

How to Make It Work:

• Adapt in real time. If A/B testing shows an underperforming element, tweak it mid-campaign to improve results.

• Look beyond donations. Analyze engagement and retention trends to refine future strategies.

By consistently testing and analyzing performance, nonprofits can optimize their outreach and increase fundraising success over time.

Final Thoughts

Addressing these omnichannel marketing challenges can unlock the full potential of your fundraising strategy. By integrating digital and direct mail efforts, personalizing donor communications, and continuously optimizing through A/B testing, nonprofits can strengthen engagement and build lasting donor relationships. A data-driven, unified approach leads to more impactful campaigns and long-term fundraising success.

The Importance of Mail Testing Tools in Email Marketing

Email marketing remains one of the most powerful and cost-effective ways to connect with your audience, build relationships, and drive sales. But there's one catch—your beautifully designed email campaign won’t matter if it never lands in your audience’s inbox. This is where mail testing tools come in.

In a world where inboxes are flooded with promotional content, standing out is tough, and deliverability is everything. Even a minor mistake or a small spam trigger in your email can send it straight to the spam folder. That’s why understanding how your email performs before hitting send is crucial—and why mail testing tools are a must-have in every marketer’s toolkit.

What Is Mail Testing?

Mail testing is the process of evaluating your email content, structure, and technical setup before launching your campaign. Think of it as a quality check for your emails.

A good mail testing tool checks:

• Spam score

• Sender reputation

• Header and DNS records (SPF, DKIM, DMARC)

• HTML formatting

• Link validity

• Blacklist status

By analyzing these elements, mail testing tools help identify potential issues that could harm your email deliverability.

Why Spam Score Matters

One of the biggest aspects mail testing tools evaluate is the spam score of your email. Spam score is a calculated value based on how likely your email is to be flagged as spam by email providers like Gmail, Yahoo, and Outlook.

Your spam score can be influenced by:

• Spam-trigger words (like "Free money", "Buy now", etc.)

• Poor HTML coding

• Lack of authentication protocols (like SPF/DKIM)

• Excessive links or images

• Blacklisted IP or domain

If your spam score is too high, your email won't make it to the primary inbox—even if your recipients subscribed to your list willingly. This can result in poor open rates, low engagement, and wasted effort.

The Cost of Ignoring Email Testing

Skipping email testing is like launching a product without QA. The consequences can be serious:

• Low Deliverability: Even if your content is perfect, technical issues can still send it to spam.

• Damage to Sender Reputation: ISPs track sender behavior. Frequent spam flags hurt your domain reputation.

• Lost Revenue: If emails don't land in the inbox, they can't convert.

• Wasted Resources: Time, money, and effort spent on creating campaigns can go down the drain if not tested properly.

Simply put, testing is not optional—it’s essential.

How Mail Testing Tools Help

Here’s how using a mail testing tool improves your email marketing performance:

1. Catch Problems Before You Hit Send

Mail testing tools give you a detailed view of what’s wrong with your email. Whether it’s a missing SPF record or spammy wording, you can fix it before your campaign goes live.

2. Boost Your Deliverability

By optimizing your email structure, authentication, and content, your chances of landing in the inbox increase dramatically.

3. Improve Campaign Performance

A well-tested email leads to better open rates, higher click-throughs, and improved conversions. Testing helps you get the best ROI from your email efforts.

4. Maintain a Healthy Sender Reputation

Mail testing ensures that your sending practices are clean and compliant, which helps you maintain a good sender score.

The End of the Email Marketing Honeymoon

Email marketing has been a powerhouse in ecommerce for years, delivering one of the highest returns on investment among all digital marketing channels. With direct access to an owned audience, the ability to schedule campaigns, and a strong track record in driving conversions, email has been a staple for businesses.

From transactional updates like order confirmations to promotional offers, editorial content, retargeting ads, and account verifications, email plays a crucial role in customer communication. But what happens when marketers can no longer guarantee that their messages are seen—or even measured accurately?

In 2025, major inbox changes are making it increasingly difficult to reach customers effectively. Here’s what’s changing and what it means for marketers.

---

Gmail’s AI-Powered Search: A Game Changer

Gmail’s latest update brings artificial intelligence into the mix, reshaping how emails appear in inboxes. According to Adweek, Gmail’s AI-powered inbox now functions more like a social media feed rather than a chronological list of emails. This means that messages are no longer ranked purely by send time or keywords. Instead, factors like recency, engagement (how often a user clicks on emails), and frequent contacts influence what appears first.

For instance, in Gmail’s own example, a marketing email containing the keyword “reunion” was pushed to the bottom of search results—despite being the most recent. This shift means that email visibility is no longer a given, and marketers will need to rethink their strategies to stay on top.

---

Stricter Spam Filters: A Growing Challenge

Email deliverability has never been foolproof. Since AOL introduced the first automated spam filter in 1994, email providers have been working to keep inboxes clean. Over the years, governments have reinforced these efforts with laws like the U.S. CAN-SPAM Act, reducing the flood of fraudulent emails.

However, even with these protections in place, legitimate emails—including transactional messages and security codes—sometimes land in spam folders or are blocked outright. As email filters become more sophisticated, marketers must work harder to maintain strong sender reputations and ensure their messages actually reach users.

---

The Promotions Tab and AI-Powered Prioritization

Since 2013, Gmail has been categorizing marketing emails into a dedicated “Promotions” tab, making them less visible to users. Early reports showed that this change led to a noticeable drop in engagement.

Fast forward to 2025, and AI-driven inbox sorting takes this concept even further. Services like Yahoo Mail now display only a handful of messages when users open their inboxes, filtering out most promotional content. The days of assuming emails will be seen—even if they land in an inbox—are over. AI agents are now deciding what’s important, and marketing emails often don’t make the cut.

---

Email Open Rates: A Flawed Metric

Apple’s Mail Privacy Protection (MPP), introduced in 2021, was a game-changer for email tracking. This feature prevents senders from accurately tracking open rates by preloading email images and reporting them as opened—even if the recipient never actually engaged with the email.

Within the first month of MPP’s launch, Twilio SendGrid reported that it inflated Apple Mail open rates by 22.9%. The same effect extended to Yahoo Mail, Outlook, and Gmail, making open rates an increasingly unreliable metric. Today, many email service providers attempt to estimate MPP’s impact, but AI-driven inbox changes only add to the complexity. Marketers can no longer rely on opens as a key performance indicator.

---

Click Tracking: Less Reliable Than Ever

Tracking clicks has long been a go-to method for measuring email engagement and attributing sales. However, this data is becoming less reliable due to new privacy measures.

Apple Mail and Proton now strip URL parameters that identify individual subscribers, making it difficult to track user behavior across campaigns. Additionally, fraud-protection bots designed to detect phishing attacks often click on email links, creating false engagement data. Some email service providers are filtering out bot-generated clicks, but many still report them as legitimate.

---

What This Means for Marketers

The golden age of email marketing is shifting. AI-driven inbox filtering, stricter spam controls, and privacy measures are making it harder to reach and track customers. Here’s what brands can do to adapt:

• Focus on Engagement: Encourage genuine interactions through valuable, highly relevant content.

• Optimize for Deliverability: Maintain a strong sender reputation and follow best practices to avoid spam filters.

• Shift to First-Party Data: Build relationships through loyalty programs, SMS marketing, and other direct channels.

• Adapt Tracking Methods: Use broader analytics, such as conversion rates and website activity, rather than relying solely on email metrics.

Email marketing isn’t dead, but the rules of the game are changing. Marketers who evolve with these shifts will continue to see success—while those who rely on outdated strategies may struggle to keep up.

Email Best Practices: Who’s on the Naughty and Nice List This Holiday Season?

When the holiday shopping rush kicks in, it seems like email marketing best practices take a backseat. Marketers often switch up their strategies, focusing heavily on promotions while overlooking key tactics like cart abandonment recovery.

According to a survey by Strongview and Selligent, nearly 300 email marketers revealed their holiday game plan. The majority are doubling down on promotional emails and basic marketing tactics, leaving essential programs, such as cart abandonment reminders, on the sidelines.

“Marketers are falling into the trap of shouting to their customers in an attempt to rise above the holiday noise,” said Andre Lejeune, CEO of Selligent. “Instead of using this time to strengthen customer relationships, they’re focusing solely on short-term gains. Those who align their holiday email campaigns with long-term goals will see the biggest returns.”

The Holiday Email Playbook: What's In and What's Out

• Sales and Discounts Dominate – A whopping 63% of marketers rank sales promotions as their top holiday email strategy, and 80% include them in their top three priorities.

• Cross-Selling Takes a Backseat – Product recommendations and cross-sell opportunities are largely overlooked, with fewer than 10% of marketers making them a primary focus.

• Cart Abandonment is Underutilized – Only 23% of marketers prioritize cart abandonment emails, despite their proven effectiveness.

• Post-Purchase Emails Are Overlooked – Just 26% consider follow-up emails after a purchase a key strategy.

A Shift Towards Targeting—But Not Personalization

While promotions take center stage, some marketers are still leveraging targeting techniques to make their campaigns more effective. About 39% rank segmentation and targeting as their top holiday tactic, while 56% include it in their top three strategies. However, more sophisticated approaches like open-time personalization (21%), offer testing (21%), and video in email (11%) aren’t widely adopted.

Email Marketing Budgets Hold Strong

Despite shifting priorities, email marketing remains a powerhouse during the holiday season. Half of marketers reported increasing their email marketing budgets for the 2016 holidays, while only 1.5% planned to cut back. The rest are sticking with their existing budgets.

The Bottom Line

While marketers are eager to maximize holiday sales, those who focus solely on promotions may miss valuable opportunities to engage customers. By balancing short-term sales with long-term relationship-building, brands can ensure they stay on the ‘nice list’—and in their customers' inboxes—long after the holiday season ends.
