DMARC Record Checker

Validate your domain's DMARC policy. Check syntax, policy mode, and reporting configuration.

What is DMARC?

DMARC (Domain-based Message Authentication) tells receivers what to do when SPF or DKIM checks fail.

Policy Modes

p=none (monitor only), p=quarantine (send to spam), p=reject (block delivery). Start with none, then tighten.

Reporting

DMARC can send aggregate (rua) and forensic (ruf) reports so you can monitor authentication results.

Alignment

DMARC checks that the From domain aligns with SPF and DKIM domains — strict or relaxed alignment.
