DMARC Analyzer

Check and validate your domain's DMARC (Domain-based Message Authentication, Reporting & Conformance) record

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps protect your domain from email spoofing and phishing attacks.

It works with SPF and DKIM to verify that emails sent from your domain are legitimate. DMARC allows you to specify how receiving mail servers should handle emails that fail authentication checks.

DMARC Policies:

  • none: Monitor only, no action taken on failed emails
  • quarantine: Failed emails are marked as spam
  • reject: Failed emails are rejected entirely (most secure)
