PUBLIC WEB DIAGNOSTIC
SPF Checker
Find a domain public SPF sender policy.
Methodology
Read public TXT records and keep only values beginning v=spf1. The checker does not expand includes or send an email.
What the result means
The published SPF TXT policy. Treat it as a practical observation rather than a guarantee about every user or provider.
Limitations
It does not send mail or prove message delivery. Unavailable results are reported honestly instead of guessed.
Worked example
For example.com, a result such as v=spf1 include:mail.example.net -all shows the published policy text to compare with the mail provider.
FAQ
Is SPF enough?
No. Pair SPF with DKIM and DMARC.
