What is SPF Checker?
The SPF checker validates the Sender Policy Framework record for any domain. SPF defines which IP addresses and servers are authorized to send email on behalf of your domain. Proper SPF configuration prevents email spoofing and improves deliverability by helping receiving servers verify sender identity.
