Yet another DNS checker, but runs entirely in your browser.

  • •Explains SPF and DMARC in plain English for non-technical owners.
  • •Instant results using Google's DNS-over-HTTPS without API keys.
Weaknesses

Post Description

A free tool that checks SPF, DMARC, DKIM, SSL and MX records for any business domain in 30 seconds. No backend — just HTML and Google's DNS-over-HTTPS API.

Built because 7 in 10 small businesses fail basic email security checks and have no idea.
