SPF (Sender Policy Framework) helps prevent email spoofing by allowing domain owners to specify which mail servers are authorized to send email on their behalf.
This free SPF validator checks your SPF record configuration, validates syntax and mechanisms, and tracks DNS lookup consumption to ensure you stay within the RFC 7208 limit of 10 lookups.
Proper SPF configuration is essential for email deliverability and is a key component of DMARC authentication.
