SPF Record Validator

About SPF Record Validator

Enter any domain to retrieve and analyze its SPF (Sender Policy Framework) DNS TXT record. The tool fetches TXT records via DNS over HTTPS, identifies the SPF record, parses every mechanism and qualifier (include, ip4, ip6, a, mx, redirect, all), counts DNS lookups against the 10-lookup limit, and provides a plain-English explanation. Flags common issues like too many DNS lookups, missing all mechanism, and permissive +all policies.
