Free DMARC record generator

Gmail, Yahoo and Microsoft now junk or reject mail from domains with no DMARC record. Fill this in, then add the record to your DNS as a TXT record. Nothing is sent anywhere: it all runs in your browser.

Your record

Host / name:

_dmarc.yourcompany.com

Type: TXT 路 Value:

v=DMARC1; p=none

Before you tighten the policy

  1. Stay on p=none for 1-2 weeks and read the reports: every service that sends as you (newsletter, CRM, help desk, invoicing) must pass SPF or DKIM aligned to your domain.
  2. Only then move to quarantine, and later reject. Jumping straight to reject can silently drop your own invoices and password resets.
  3. Most DNS panels want only _dmarc as the host (they add your domain). Keep exactly one DMARC record.

Already have records and still landing in spam? Check your domain free: it shows which of SPF, DKIM and DMARC is failing, in 5 seconds, no signup.
