FAQ
SPF Record Checker questions
What does an SPF record do?
It lists which mail servers are allowed to send mail on behalf of a domain.
Can a domain have multiple SPF records?
A domain should publish only one effective SPF policy record. Multiple SPF records often cause evaluation problems.
Is SPF enough on its own?
No. Most teams pair SPF with DKIM and DMARC to build a stronger authentication posture.
