What can you do?

Email Validation — Verify if an email exists via SMTP. Returns valid, invalid, catchall, or valid_catchall.

Email Finder — Enter a name and company domain. We try 16 naming conventions and SMTP-verify each until we find a match.

Batch Processing — Upload a CSV in the dashboard or submit up to 100K emails via the async jobs API.

Only Pay for Results — Invalid emails, failed finds, and catch-alls are free. You only pay when we deliver a verified result.
