}Two products, one API. Find emails and verify them.
Enter a name and company domain. We try 16 naming conventions via SMTP until we find a verified match.
Real SMTP verification, not just syntax checks. We connect to the mail server and confirm the mailbox exists.
Upload a spreadsheet, map your columns, and download enriched results. No code required.
Every lookup enriches our domain intelligence. Subsequent queries are faster and more accurate.
We don't just flag catch-alls. We use convention matching and SMTP timing analysis to tell you if the email is likely real.
Invalid emails, failed finds, and catch-alls are free. You only pay when we deliver a verified result.
Email find = 1 credit. Email validate = 0.25 credits. Only charged for valid results.
