The SPF Record Check is a diagnostic tool that acts as a Sender Policy Framework (SPF) record lookup and SPF validator. It looks up an SPF record for the queried domain name, displays the SPF Record if found, and runs a series of diagnostic tests (SPF Validation) against the record, highlighting any errors found with the record that could impact email delivery.
