Clean your email list before you send. Upload a CSV or use the API: every address comes back valid, invalid, catch-all, risky or unknown, with a score and a plain-English reason. What's different: catch-all and unknown results are refunded, duplicates are charged once, credits never expire, no subscription. 100 free checks every month, EU servers, API, webhooks and an MCP server for AI agents.

Partial The upload, credits and API are easy to build, but accurate verification requires SMTP probing, catch-all detection and sender reputation infrastructure that vibe coding alone won't provide.
What it would actually take: The app layer (CSV upload, credits, billing, API) is standard. The core is an email verification engine: DNS/MX lookups, SMTP handshakes with careful rate-limiting, catch-all detection, and multiple dedicated IPs to avoid blacklisting. Building it well requires deliverability and mail-systems expertise, or wrapping a third-party verifier and accepting its margins and dependency.
