How to use this free DMARC checker

DMARC tells receiving mail servers how to handle messages that fail aligned SPF or DKIM authentication. Enter the domain or URL above and review the returned records and status details. The results reflect the information available when the check runs.

Understanding your DMARC results

A missing DMARC record means the domain has no published DMARC policy. Start with a monitoring policy while you verify legitimate senders.

A published p=reject policy can help prevent unauthenticated spoofing, but only when legitimate email sources are properly authenticated.
