DMARC Aggregate Reports (rua) (DMARC Aggregate Reports)
The Importance of DMARC Aggregate Reports
Aggregate reports provide visibility into who is sending email using your domain - both legitimate services and unauthorized senders. Without these reports, you are blind to email spoofing attempts and cannot verify that your authentication is working correctly across all email services.
Reports are typically sent daily by major email providers (Google, Microsoft, Yahoo, etc.). They are XML files that can be difficult to read raw. DMARC reporting services (like Postmark DMARC, DMARC Analyzer, or dmarcian) parse these reports into readable dashboards showing authentication pass/fail rates, sending sources, and trends.
The data from aggregate reports is essential for the DMARC rollout process. They show you which email sources are not yet authenticated, allowing you to fix SPF and DKIM configuration before moving to an enforcing policy. Without this data, advancing to p=quarantine or p=reject is risky.
Testing Your Configuration
Configure the rua tag in your DMARC record to receive aggregate reports: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com. Use a DMARC report analyzer service to parse the XML reports into actionable data. Check reports weekly to monitor authentication health.
