DMARC checker
DMARC Checker
Look up the DMARC policy published for a domain and understand what its key settings ask receiving mail servers to do.
Free DNS lookup
Check a domain
Enter a domain, website URL, or email address. We’ll look up its published DMARC policy.
What we check
The checker requests the TXT record at _dmarc.your-domain and parses its policy tags.
What the policy means
A DMARC policy tells receivers how the domain owner asks them to handle messages that fail authentication.
What it does not prove
A published record is one email-authentication control, not a guarantee of security, identity, or delivery.
