DMARC Checker

Find and read a domain’s DMARC record — its policy strength (none, quarantine, reject) and whether it collects reports.

What DMARC does

DMARC tells receivers what to do when SPF and DKIM fail alignment, and where to send reports. It’s how you actually stop others spoofing your domain.

Move off p=none

A record at p=none only monitors — spoofed mail still gets delivered. After reviewing your aggregate (rua) reports, tighten to p=quarantine and then p=reject to enforce.

Frequently asked questions

▸ Is p=none enough?

No — p=none only monitors and gives reports; spoofed mail is still delivered. Move to p=quarantine then p=reject once your legitimate senders pass.

▸ Where does the DMARC record live?

In a TXT record at _dmarc.yourdomain.com, starting with v=DMARC1.
