11 Essential Metrics to Analyze in Your Gmail DMARC Report

When it comes to email security, DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a crucial protocol. If you're using Gmail for your business communications, analyzing your DMARC report is vital to ensure the security and integrity of your email system. In this blog post, we'll explore the 11 essential metrics you should analyze in your Gmail DMARC report.

1. Total Email Volume

This metric gives you an overview of the total number of emails sent from your domain. Monitoring this volume helps identify any unusual spikes or dips, which could indicate a potential security issue or a change in email sending patterns.

2. Authenticated Emails

Authenticated emails are those that have passed DMARC validation checks. A high percentage of authenticated emails indicates a robust email authentication setup, reducing the chances of spoofing and phishing attacks.

3. Unauthenticated Emails

Emails that fail DMARC authentication are considered unauthenticated. A high number of unauthenticated emails could suggest configuration issues or malicious activity. It's essential to investigate these emails to understand why they're failing authentication.

4. Forwarded Emails

Forwarded emails are messages that have been redirected from their original recipient to another address. Monitoring this metric helps identify potential information leaks or unauthorized forwarding activities.

5. SPF (Sender Policy Framework) Pass/Fail

SPF is a key component of DMARC, helping to validate the sending IP address. Analyzing SPF pass/fail rates is crucial to ensure that only authorized servers are sending emails from your domain.

6. DKIM (DomainKeys Identified Mail) Pass/Fail

DKIM adds a digital signature to outgoing emails, verifying their authenticity. Monitoring DKIM pass/fail rates helps identify any tampering or forgery attempts.

7. DMARC Policy

Your DMARC policy defines how unauthenticated emails should be handled. Regularly reviewing this policy ensures it aligns with your organization's security requirements.

8. Quarantined Emails

Emails quarantined due to failing DMARC checks should be closely monitored. These emails might contain valuable information about attempted spoofing or other security threats.

9. Rejected Emails

Emails rejected due to DMARC policies are a critical indicator of potential security breaches. Analyzing these rejections can help prevent future attacks.
