Q & A Email Auth · September 11, 2026

What should a DMARC RUA address look like?

The rua= tag names where DMARC aggregate reports get sent. Format: rua=mailto:[email protected]. You can list multiple addresses comma-separated: rua=mailto:[email protected],mailto:[email protected]. If you use a DMARC processor (dmarcian, EasyDMARC, Valimail, Postmark), use their provided address — e.g., rua=mailto:[email protected]. If the address is on a different domain than yours, that domain must publish a special cross-reporting TXT record authorizing the reports (most processors ship this automatically). Look up any domain’s DMARC record with the DMARC lookup tool.

What Is DMARC?
DMARC is the enforcement layer of email authentication. SPF and DKIM do the checking — DMARC tells receiving servers what to do when they fail, and reports back to you who's sending email using your domain.
