If you’re serious about optimizing your email strategy, DMARC monitoring is an essential practice for ensuring your messages hit the inbox as intended.
As inbox providers increasingly roll out support for Brand Indicators for Message Identification (BIMI), it’s crucial for every sender to prepare effectively. BIMI enables brands to display their logos in the inbox, which can boost sender visibility and engagement rates.
To leverage BIMI, you need more than just a Domain-based Message Authentication, Reporting & Conformance (DMARC) record; your DMARC policy must be set to enforcement (either quarantine or reject). However, transitioning to DMARC enforcement should only happen once you're confident that all legitimate emails are passing DMARC.
This is where DMARC monitoring comes into play.
What is DMARC Monitoring?
DMARC monitoring involves analyzing DMARC reports to detect unauthorized senders attempting to spoof your domain.
When you set up a DMARC record, you designate an email address to receive DMARC reports. These reports are invaluable, though they can be challenging to decode. Typically, raw DMARC reports are XML data files detailing IP addresses and authentication statuses of emails.
A specialized DMARC monitoring tool can transform this complex data into actionable insights. After setting up your account with such a tool, you’ll gain access to a user-friendly dashboard that simplifies the data, helping you make informed decisions about your DMARC policy and manage third-party senders.
How to Get Started with DMARC Monitoring
Effective DMARC monitoring is crucial for the security of your email program and is a step toward enabling BIMI. Follow these steps to set up and maintain DMARC monitoring:
Publish Your DMARC Record Start by creating and publishing your DMARC record. Make sure to include the reporting address in the rua tag so that DMARC reports are sent to your chosen monitoring tool. Your DMARC record should look something like this:
cssv=DMARC1; p=none; rua=mailto:your-reporting-email@example.comCreate Your DMARC Monitor Account Once your DMARC record is live, create a free account with your chosen DMARC monitoring service. This will allow you to start receiving and analyzing your DMARC reports.
Verify Your Sending Sources With access to your monitoring dashboard, focus on the data to ensure no unauthorized parties are using your domain. Examine the sending services listed, and verify their legitimacy. If you spot any unfamiliar sources, investigate whether someone within your organization is sending emails using your domain or if there is potential spoofing.
Reach DMARC Enforcement Once you’ve confirmed that all your legitimate emails pass DMARC, update your DMARC policy to “quarantine” or “reject” to enforce DMARC. This step ensures only authorized sources can send emails from your domain. A “none” policy won’t support BIMI implementation.
Ongoing Monitoring Even after setting a policy of “quarantine” or “reject,” continue to monitor your DMARC reports. Changes in sending services or updates from existing ones can affect your email authentication. Regularly review daily DMARC reports to check the status of your authorized services and identify any new services or issues that arise. Adjust SPF and DKIM records as needed to maintain accuracy.

What is a DMARC Service?
A DMARC service is a third-party tool or software that aids in implementing and managing DMARC policies. These services simplify the DMARC setup process, provide real-time monitoring, and generate detailed reports. They also offer expert guidance on best practices for email authentication, helping to safeguard your domain against unauthorized use.
Key Benefits of DMARC Services:
- Simplified Setup: User-friendly interfaces for configuring DMARC policies and DNS records.
- Real-time Monitoring: Alerts for authentication issues as they occur.
- Detailed Reporting: Comprehensive insights into email usage and potential threats.
- Expertise: Specialized knowledge for effective implementation and management.
DMARC Monitoring Takeaways
DMARC monitoring helps you keep track of who sends emails from your domain, block unauthorized senders, and achieve DMARC enforcement. While it’s not a panacea, enforcing DMARC enhances your email security and prepares you for BIMI, potentially boosting brand recognition and trust with your recipients.
