About the DMARC Generator tool

Generate a DMARC record with the right policy, reporting and alignment settings.

Results are generated live. Each finding is graded as an error, warning or pass and explained so that you know what to fix and why it matters.

Get alerted when this check starts failing, when you land on a blacklist or when a certificate or domain is about to expire.
