DMARC checker

Look up a domain’s current DMARC record, enforcement policy, test mode, and reporting destinations.

Read policy separately from authentication

A published DMARC record states how the domain owner wants receivers to handle aligned authentication failures. It does not show whether a particular message passed SPF or DKIM.

This checker follows the current RFC 9989 tag model, including np and t. Read the RFC 9989 migration guide before changing an older policy.
