DMARC record generator
Choose a policy and a report address and copy a correct DMARC record. Start at p=none, then tighten it once the reports show your real senders pass.

Keep your domain on your radar
A one-time check shows today. Pistos DMARC reads the reports mailbox providers send about your domain and tells you when a sender fails or a record changes.
Questions
Does this tool publish the record for me?
No. It builds the text. You add it as a TXT record at your DNS host, with the host name _dmarc.
What report address should I use?
An address that can receive many automated XML files, ideally a reporting service rather than a personal mailbox. If it is on another domain, that domain must authorize it.
Is anything stored?
No. The record is built in your browser and never leaves it.
About this tool
What the generator builds
A single TXT record for _dmarc.yourdomain with the tags in the right order: v=DMARC1, the policy, the report address, and optional subdomain policy, percentage and alignment tags.
Which policy to pick
p=none is monitor only and cannot block mail, so it is the safe place to start. p=quarantine sends failing mail to spam. p=reject refuses it. Move up only after reports show every legitimate sender passing.
After you publish
DNS can take a few minutes to a few hours. Run the DMARC checker to confirm the record is live and valid, then watch the reports for a few weeks.
