Processed on your device

Create a DMARC record for your domain: choose the policy and where reports go, then copy it into your DNS.

Uses the current DMARC standard (RFC 9989, 2026), which dropped the old pct tag. Use test mode instead to try a policy gently.

How to use

  1. Add your text or file.
  2. Adjust the options if needed.
  3. Copy or download the result.
