EU-hosted email verification API with zero retention: honest verdicts instead of a fake valid, refunds on inconclusive checks, and MCP for AI agents.

Hey Product Hunt 👋

I’m Hugo, a developer from Lille, France. PricklyMails started from something I saw at work: companies trying to reactivate CRM databases that had been sleeping for years, with no idea how many addresses were still alive.

Sending to those lists blindly is how you wreck a sender reputation.

So I built an email verification engine in Rust. You drop a CSV or call the API, and every address gets a clear verdict: send, review or remove.

A few things I cared about:
🇪🇺 Hosted in the EU, and not a single verified address is stored.
🎯 You choose which checks to run and only pay for those.
💸 If a check can’t get an answer, it’s refunded, never silently marked as valid.
🤖 MCP server, so Claude, Cursor or ChatGPT can verify emails for you.
🧪 Test keys to build your integration without spending a token.

I’d love your honest feedback, especially if you send cold emails or manage large lists: what’s the one thing your current verifier gets wrong?

🎁 Launch offer for the Product Hunt community: sign up and get 10,000 free tokens, about 1,000 full verifications, enough to clean a real list and see the verdicts for yourself. Valid until November 11.

If you try it, I’d love to hear what you verified and whether the send / review / remove verdicts matched what you expected 🦔
