Email verification and finding, built for developers
Check whether an address can receive mail, or find a person's work email from their name and company domain. Plain REST, JSON, one API key. Honest verdicts, you only pay when we earn a definitive answer.
Verify one email
Real-time deliverability for a single address, with a graded risk score. 1 credit on a decisive result.
Verify in bulk
Upload a CSV of up to 500k rows, we process it in the background and stream progress.
Find a work email
Give us a name and a company domain, get the most likely deliverable address back.
Webhooks
Get a signed callback the moment a verification or bulk job finishes. No polling.
Every endpoint answers with the same envelope, data on success, error on failure, so you branch once and reuse everywhere.
{ "email": "[email protected]" }
// 200 { "status": "success", "data": { "result": "ok", "quality": "good", "risk_score": 8 }, "error": null }
MCP server
Point Claude, Cursor, or any Model Context Protocol client at our engine and verify or find emails right in a chat.
Zapier, Make, n8n
No-code automations that verify signups and clean lists, powered by the same API.
Stable error codes
Every failure returns a numeric code you can branch on, never a free-text string that changes.
