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.
