Where is a DMARC record published?

DMARC is published as a TXT record on _dmarc.yourdomain.com.

Is p=none enough for Gmail bulk senders?

It may be enough to start monitoring, but bulk senders should plan a path toward quarantine or reject once mail streams are authenticated.

Can this tool read DMARC aggregate reports?

This checker reads DNS only. A report viewer is a natural next feature after the first launch.

What this checker validates

The tool looks for a DMARC TXT record at _dmarc.yourdomain.com, checks the policy tag, flags duplicate records, and highlights missing reporting or relaxed alignment choices.

Recommended first fix

If the domain has no record, publish a starter policy with p=none and rua reporting, then move to quarantine or reject after your legitimate mail streams pass SPF or DKIM alignment.
