PUBLIC WEB DIAGNOSTIC

DMARC Checker

Inspect the policy used for failed email alignment.

Ready for a public check.

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.
