How to publish your SPF record

  1. Copy the record above.
  2. In your DNS provider, add a TXT record at the root of your domain (host @).
  3. Paste the record as the value and save. Publish only one SPF record per domain.
  4. Wait for DNS to propagate, then confirm with the SPF checker.

Keep your SPF under 10 DNS lookups. Next, set up DMARC for full protection.
