Rollout tip

Start at p=none and watch reports for 1-2 weeks. Once your legitimate senders align, move to quarantine, then reject.

How to publish your DMARC record

Add a TXT record at the host shown (_dmarc.yourdomain) with the generated value in your DNS provider. DMARC starts working within a few hours. Then paste your domain into our DMARC Checker to confirm it resolves.
