Show HN: I built a free email security checker for small businesses (shielddeskhq.com)

3 points by minhajulmahib 4mo ago ↗ HN

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.

hey, congrats on the launch, your own tool is flagging shielddeskhq.com at 35, worth a quick fix.
