Free DMARC Record Checker

Enter a domain to look up its DMARC record. We'll show whether DMARC is configured, the policy in use, and whether spoofed emails will be enforced.

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a TXT record published at _dmarc.yourdomain.com. It tells receiving mail servers what to do with messages that fail SPF or DKIM checks: reject them, quarantine them as spam, or just monitor and report. Without DMARC, anyone can spoof your domain and trick your customers.

What we check

  • Record presence — whether _dmarc.yourdomain resolves to a TXT record starting with v=DMARC1
  • Policy — p=none (monitor), p=quarantine (spam folder), or p=reject (block)

How to fix

Add a TXT record at _dmarc.yourdomain.com with a value like v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com. Start with p=none for two weeks to review reports, then move to p=quarantine, then p=reject. Tools like dmarcian or Postmark DMARC are useful for parsing the aggregate XML reports.
