DMARC Record Generator

Build a DMARC policy step by step. Start with p=none, read your reports, then tighten.

How to use the DMARC generator

Start with policy none and an aggregate report address (rua). Publish the record as a TXT record with the host name _dmarc. After a few weeks of clean reports, change the policy to quarantine and then reject.

DMARC only passes when SPF or DKIM passes for the same domain as your From address. Read the step-by-step DMARC guide and confirm your record with the DMARC Checker.
