Email DNS Health Checker

One report for SPF, DKIM, DMARC and MX, scored 0-100 with specific fixes.

What this checks

We resolve your SPF, DMARC and DKIM records plus your MX servers, validate each against best practice, and roll it up into a single health score so you know exactly what to fix first.

From here to enforcement

Green across the board means you can safely move DMARC toward p=reject. DeliverSignal watches all of this daily and alerts you the moment something regresses.
