DMARC record generator
Build a v=DMARC1 TXT record with policy, percentage, and rua. Nothing is uploaded.
Fill the fields, then run the tool.
How to use the DMARC record generator
- Set policy (none, quarantine, or reject) and an aggregate report mailbox.
- Optional: percentage, fo, adkim, aspf.
- Copy the value to _dmarc.your-domain TXT.
Start on p=none
Watch rua reports before quarantine or reject. This page defaults to none so you do not lock mail on day one.
Nothing is uploaded
The string is local. You still have to create the DNS record at your registrar or DNS host.
