DMARC Record Checker
Check your DMARC policy, verify reporting addresses, and get recommendations to strengthen your email security posture.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is the policy layer that ties SPF and DKIM together. It tells receiving servers what to do when authentication checks fail: nothing (none), send to spam (quarantine), or reject the email entirely (reject).
Since 2024, Gmail, Yahoo, and Microsoft require DMARC for all bulk senders. Without DMARC, your emails are more likely to land in spam, and your domain is vulnerable to spoofing attacks.
DMARC policy progression
Start with p=none to collect reports without affecting delivery. Once you confirm that all legitimate senders pass SPF and DKIM, move to p=quarantine, then finally p=reject for maximum protection.
