Show HN: I built a free email security checker for small businesses

Operating in show hn launch, I built a free email security checker for small businesses operates.

Profile

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.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

It is recorded at the Show HN launch stage.
