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

- datafreak_ 5mo agohey, congrats on the launch, your own tool is flagging shielddeskhq.com at 35, worth a quick fix.
- minhajulmahib 5mo agoYou're right — fixing it now. SPF and DMARC records need updating on my end. Appreciate you scanning it
- sds357 5mo agoSecurity report for shielddeskhq.com 43 Security Score / 100 Vulnerable — Your domain can be spoofed.
- minhajulmahib 5mo agoGood catch — embarrassing that my own domain scores 43 on my tool. Fixing the DNS records now. Thanks for actually testing it.
