DMARC Generator

The DMARC Generator builds a syntactically correct DMARC TXT record for your domain based on the choices you make in the form — policy (none/quarantine/reject), subdomain policy, alignment mode, reporting addresses, percentage and DKIM/SPF requirements. The generated record can be copy-pasted directly into your DNS host at the `_dmarc` subdomain, saving you from hand-typing tag=value pairs and getting the delimiters wrong.

Getting DMARC syntax right on the first try is important because a malformed record is silently ignored by receivers — you'll think DMARC is protecting your domain when in fact it isn't. Common mistakes include missing semicolons, wrong tag names (rua= vs mailto:), and reporting addresses that receivers can't send to because your domain hasn't published a mailto authorization for the target inbox.

This generator produces records that follow RFC 7489 exactly, and pairs perfectly with our DMARC Checker for verifying the record once it's live. If you're deploying DMARC for the first time, start with a monitoring-only policy (p=none) with a valid rua= address, and only escalate to quarantine or reject after two weeks of clean reports.
