Email Health Check

Get a combined SPF + DMARC health grade (A–F) with a per-check breakdown and actionable recommendations.

What is an Email Health Check?

Email authentication relies on two DNS records working together: SPF (Sender Policy Framework) authorises which mail servers may send on your behalf, and DMARC (Domain-based Message Authentication, Reporting and Conformance) tells receivers what to do when SPF or DKIM checks fail. A misconfigured or missing record leaves your domain open to spoofing and phishing attacks.

This checker looks up both records simultaneously, validates each one, and combines the results into a single health grade — making it easy to spot problems and understand what to fix.
