Build a DMARC record, one question at a time.

Answer a few plain-English questions and we assemble a valid v=DMARC1 record for you. Start in monitor-only mode, point reports somewhere you can read them, and tighten the policy as you gain confidence.

Policy

Monitor only. Receivers take no action on failing mail; you just collect reports. Start here.

Publish this record in DNS

Add one TXT record at the host below. It updates live as you change the options above.

Host / name
_dmarc
Type
TXT
Value
v=DMARC1; p=none

What to do next

  1. 1.Publish the TXT record above at _dmarc. DNS can take a few hours to propagate.
  2. 2.Watch the aggregate reports for a week or two to confirm your real senders pass before tightening the policy.
  3. 3.Re-run the DMARC audit to confirm the published record parses the way you expect.
