SPF Checker

The Sender Policy Framework (SPF) record is a type of DNS TXT record that specifies which mail servers are authorized to send email on behalf of your domain. SPF helps prevent email spoofing and improves email deliverability by allowing receiving mail servers to verify that incoming email comes from an authorized sender.

Use our SPF checker tool to verify your domain's SPF record and ensure your email authentication is properly configured.

Check any domain's SPF record by entering it above. Make sure your SPF record includes all authorized sending servers.
