Email security grader

Can someone send email pretending to be you? Check your domain's SPF, DKIM and DMARC and get a grade.

We only read your public DNS records. Nothing is sent to your mail servers.

What we check

  • SPF lists who is allowed to send email as your domain.
  • DKIM signs your email so receivers can tell it hasn't been tampered with.
  • DMARC tells receivers what to do with email that fails those checks.

Missing or weak records make it easy for criminals to send convincing fake invoices in your name.
