Free DMARC Checker

Enter a domain to find its published DMARC TXT record, review the current policy posture, and get practical next steps for moving toward stronger enforcement.

How this works

The checker looks up the public TXT record at _dmarc for the domain you enter, parses common DMARC tags like p=, sp=, pct=, and rua=, then summarizes what to fix or improve next.
