DMARC Record Checker

Analyze your DMARC (Domain-based Message Authentication, Reporting & Conformance) policy. DMARC ties together SPF and DKIM to protect against email spoofing.

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on SPF and DKIM to give domain owners control over what happens when authentication fails. It also provides reporting so you can monitor email authentication results.

DMARC Policies Explained

none

Monitor only - no action taken on failing emails

quarantine

Failing emails are sent to spam/junk folder

reject

Failing emails are blocked entirely (strongest protection)
