Real-time email verification API — actual SMTP handshakes, not just syntax checks. Resolves catch-alls, even behind Proofpoint/Mimecast, where most tools return "unknown." Every result ships reasons[] and a calibrated confidence score, never laundered into a false "deliverable." MCP server for Claude/Cursor, or bulk CSV. Unknown results are free. We verify your list and stop there — encrypted at rest, retention you set. 100 free credits, no card.

Could you build this?
Partial A basic syntax and MX check is trivial, but real-time SMTP handshakes that accurately determine deliverability without being IP-blacklisted, plus bypassing Proofpoint/Mimecast catch-alls, requires complex infrastructure.
What it would actually take: Requires an orchestrator managing rotating pools of clean IPv4/IPv6 addresses with configured rDNS, SPF, and DKIM to prevent immediate blacklisting by enterprise mail gateways. It also needs specialized SMTP state machine logic capable of detecting behavioral tarpitting, greylisting, and catch-all response heuristics unique to enterprise security vendors like Proofpoint, Mimecast, and Barracuda.
