DomSec HQ checks your domain's email authentication and web security in seconds - SPF, DKIM, DMARC, BIMI, MX, blacklist status, MTA-STS, TLSRPT, DNSSEC, SSL/TLS, and security headers. 5 checks are free with no signup; create a free account to unlock all 11 plus a downloadable PDF report. Built because most small businesses don't find out they're missing SPF/ DKIM/DMARC until Google or Yahoo start silently dropping their mail into spam
Hi Product Hunt 👋 Maker here.
I built this after noticing how many small businesses don't realize their
email authentication is broken until it's already costing them delivered
mail. Ran the scanner against our own domain before launch as a gut-check
and actually found a real issue (DMARC set to p=none - present but not
enforcing) - wrote that up here if you're curious what that looks like in
practice: https://domsechq.com/blog/we-fou...
Free tier needs no signup for the core checks. Would love feedback on
what's confusing or missing.
