New to DMARC? Start with p=none and a valid rua address, watch the reports for a few weeks, then move to quarantine and finally reject.

How it works

A valid DMARC record, built to be rolled out safely.

Choose your policy, add a reporting address, set alignment and percentage, and copy a correct record for your _dmarc subdomain — designed for a gradual none → quarantine → reject rollout.

  1. 01

    Pick a policy

    Start at p=none to monitor, then graduate to quarantine and reject as your reports come back clean.

  2. 02

    Add reporting

    Set an rua address to receive aggregate reports — the data that tells you when it's safe to enforce.

  3. 03

    Copy & publish

    Add the generated record as a TXT entry at _dmarc.yourdomain.com. Tune alignment and pct only if you need to.
