What is DMARC / SPF / DKIM Checker?

The DMARC/SPF/DKIM Checker analyzes email authentication DNS records for any domain. It checks for DMARC, SPF, and DKIM policies and provides a security score showing how well the domain is protected against email spoofing and phishing attacks.

Use Cases

  • Security auditing — check if your domain is protected against email spoofing
  • Vendor assessment — verify that business partners have proper email security
  • Domain migration — confirm email authentication records are correctly configured after DNS changes
  • Compliance checking — many regulations require proper email authentication

Key Features

✓SPF record validation with mechanism parsing
✓DKIM selector checking (common selectors: default, google, selector1, selector2)
✓Overall email security score (0–100)
