DMARC tool
DMARC record generator
Pick a policy and, if you want reports, an address for them. You get a valid record to publish, like the example, checked in code.
Publish this at _dmarc.yourdomain.com as a TXT record. Already have a DMARC record? Use the DMARC checker to validate and safely upgrade it instead — this generator is for starting from scratch.
No DMARC record yet? Pick a policy and we'll build a valid record for you to publish, free — deterministic tag assembly, self-checked against the same validator our DMARC checker uses. If you already have a record, use the checker instead — it upgrades in place rather than starting over.
Diagnose your domain
Check SPF, DMARC, DKIM, MX, DNS health, blacklists and domain & SSL expiry in one free scan — with the exact record to paste in to fix each problem.
