PUBLIC WEB DIAGNOSTIC
DMARC Checker
Inspect the policy used for failed email alignment.
Methodology
Read TXT at _dmarc.domain and display the published policy without processing private reports.
What the result means
DMARC text and common policy tags. Treat it as a practical observation rather than a guarantee about every user or provider.
Limitations
Private aggregate reports are never exposed. Unavailable results are reported honestly instead of guessed.
Worked example
For example.com, a record with p=quarantine and pct=100 indicates the requested handling for failed alignment.
FAQ
Where is it published?
Normally as TXT at _dmarc followed by the domain.
