What is Domain Spam Score (%)?

Domain Spam Score (%) is a quick way to estimate technical risk signals that can impact trust, email deliverability, and user safety. This tool checks DNS/email authentication (MX, SPF, DMARC), HTTPS availability, redirects, and security headers (HSTS, CSP, etc.) to compute a score from 0% (low risk) to 100% (high risk).

How to reduce spam score

  • Add SPF and DMARC to prevent spoofing and phishing.
  • Enable HTTPS and consider enforcing HSTS.
  • Reduce unnecessary redirects and keep clean URL structure.
  • Implement security headers: CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy.
