FREE TOOL

Email DNS health checker

Enter any domain and check your SPF, DKIM, DMARC, and MX records in real time. Know whether your domain is configured to deliver before your first campaign sends.

Real-time lookup

Checks live DNS records, not cached data. What you see is what mail servers see right now.

Four checks in one

SPF, DKIM, DMARC, and MX checked simultaneously. No need to use four separate tools.

Fix instructions included

Every failed check includes the exact record you need to add to fix it.

DNS checks run automatically inside ForgeSend

ForgeSend runs these same DNS checks as part of the pre-send guardrail checklist — before every campaign launch.
