What is a DMARC Aggregate Report?
DMARC aggregate reports are XML files sent daily by email receivers (Google, Microsoft, Yahoo, and others) to domain owners who have configured a rua tag in their DMARC record. Each report summarizes how messages from your domain were authenticated and what actions were taken.
These reports tell you which IP addresses are sending email on behalf of your domain, whether SPF and DKIM checks passed, and whether the sending domains aligned with your From header — the core of DMARC evaluation.
