DMARC Policy Lookup

About DMARC Policy Lookup

The DMARC Checker fetches the TXT record published at _dmarc.yourdomain.com and evaluates the policy, percentage alignment, and failure report configurations.

How to Use This Tool:
  • Type in any domain name.
  • Hit "Check DMARC".
  • Verify if a valid v=DMARC1 record is detected and whether policy enforcement is active.
Frequently Asked Questions

This means you haven't created a TXT record with host _dmarc. Unprotected domains are vulnerable to email spoofing and phishing attacks.
