SPF Record Checker

Validate any domain's SPF record against the RFC 7208 lookup limits — no account required. We run the same engine the OnlyDMARC platform uses.

Enter a domain to check

We'll look up the SPF record for the domain and count its DNS lookups against the RFC 7208 limit of 10.

  Free and anonymous — no account, no sign-up. Runs the same RFC 7208 engine as the OnlyDMARC platform.

See a sample result what a checked domain looks like — no lookup performed
Example: too many DNS lookups

A record with 12 lookups would show a red verdict, a 12 of 10 lookup meter, and a recommended fix to flatten or trim includes. This is a static illustration — run a real check above to see your domain.
