What does the DMARC rua= tag do?

DMARC `rua=` Tag — Aggregate Report URI (rua)

The DMARC rua tag specifies where ISPs send daily aggregate XML reports showing who is sending mail from your domain. Essential for DMARC visibility.

Tag

mailto: Email address to receive reports (most common). The receiving domain must either match or publish a DMARC record allowing external reports.

https: URL endpoint (rarely used; limited receiver support).

💬 What This Tag Does

The "rua" tag tells receiving ISPs where to send daily aggregate reports in XML format. These reports show every IP that sent mail claiming to be from your domain, along with SPF and DKIM pass/fail counts. Without rua, you're flying blind — you'll have no visibility into who is sending as your domain or where your configuration is failing.
