How to Publish a DMARC Record with Cloudflare

DeploymentTechnical Guidance

For those of you that use Cloudflare as your DNS provider, here are brief instructions for adding a DMARC record. If your domain has been added to Cloudflare through one of their partners, you’ll manage your DNS records through that hosting partner.

  1. Create your domain’s DMARC record.
    • If you have already generated a DMARC record, you can verify it with our free diagnostic tool.
    • If you need to generate a DMARC record, you can use our free DMARC Record Wizard
  2. When you have created and verified your DMARC record, log in to your Cloudflare dashboard.
  3. Click the Cloudflare account for the relevant domain.
  4. Select the domain.
  5. Click the DNS app.
  6. The user interface for adding DNS records is under DNS Records.
  7. Replace Name with a subdomain or the root domain. For compliance, the Name should follow these Internet standards:
    • 63 characters or less
    • Start with a letter
    • End with a letter or digit
    • Contain only letters, digits, or a hyphen as the interior characters
    • Cloudflare discourages using underscores because of limited browser support
  8. Choose TXT in the Type for your DMARC record.
  9. Add your TXT record by replacing Value with your DMARC record and click Add Record.

You can verify that your DMARC record is properly published using our DMARC Record Checker. Note: it may take up to 48-hours before your record propagates, dependent on your DNS host.
