SPF Checker

Inspect your published SPF record, included policies and DNS-lookup limits.

01 / INPUT

Does the SPF record describe the right sources?

STEP 01
Enter the sending domain—not a website URL or email address.

This check reads public DNS through Sky’s fixed resolver. It does not receive a message or change a record.

Your DNS query is sent to Sky’s server and its fixed public resolver to complete the lookup. It is not added to tool history. Ordinary hosting access logs may still exist.

NEXT / INTERPRET THE EVIDENCE

Use this result with the sending path, receiver response and authorized provider signals—not as a stand-alone placement verdict.
