Security Check

Instant domain and email security scan

Enter your email address to verify SPF, DKIM, DMARC, MTA-STS, TLS reporting, SSL, and hosting performance. We only test the domain.

We only test the domain, and use your email to send the report.

What we check

  • Impersonation protection: DMARC enforcement (quarantine/reject) to block spoofing.
  • SPF: which servers are allowed to send email for the domain.
  • DKIM: cryptographic signing to confirm message integrity.
  • DMARC: alignment policy and reporting for failed authentication.
  • MTA-STS: enforces TLS for inbound email delivery.
  • TLS-RPT: reporting endpoint for TLS delivery failures.
  • Email provider: Google Workspace, Microsoft 365, or self-hosted based on MX.
  • SSL encryption rating: HTTPS availability and certificate validity.
  • Website security rating: HTTPS and HSTS presence.
  • Hosting speed: estimated response time for the homepage.
