Hey Product Hunt! 👋 I built this because I was tired of "verification" tools that just hand you a green checkmark and call it a day. A pass/fail doesn't tell you why an address is risky, so you're still guessing when it actually matters for your list. MailTooth runs every email through a multi-layer engine, syntax, DNS/MX, role-based and disposable detection, SMTP mailbox-level verification, catch-all detection, WHOIS, TLD risk, and hands you back a real score with the reasoning behind it. Not a guess. Evidence. A few ways to use it: → Verify one email in real time via API → Clean entire lists in bulk (CSV / Excel) → Find and verify emails on the fly with our Chrome extension → Give your AI agents a deliverability checkpoint via MCP, before they ever send or create a CRM record You can also pick Quick, Standard, or Deepcheck, depending on how much evidence a decision deserves. For today only, Product Hunt gets {bump this: 100 → 500} free credits, no card required. Just sign up and you're in. Would love to hear what you think, I'll be here all day answering questions. Thanks so much for checking us out 🙏
