What Is SPF?

📧 Authorized Senders

SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of your domain, helping prevent email spoofing and phishing.

âś… Validation & Errors

Our checker validates your SPF record syntax, checks for common configuration errors, and identifies issues that could impact your email deliverability.

  • SPF record existence and proper DNS configuration
  • Record syntax and formatting validation
