VerifyFlow verifies emails. For finding emails, pair VerifyFlow with a prospecting tool — then run every address through real SMTP checks where the provider allows them before your campaign goes out.
Verify Your Found Emails FreeAn email finder discovers likely email addresses for a person or company — usually by guessing common patterns (first.last@, first@) and checking public sources. It gets you a list of candidate addresses, but not proof that those addresses are real or deliverable.
Use your prospecting or email-finder tool to build a list of candidate addresses.
Run that list through VerifyFlow. Real SMTP checks where the provider allows them. Where they don't (for example Microsoft 365 and Yahoo), the address is marked PROTECTED instead of guessed.
Export only the SAFE and PROTECTED addresses to your sending tool and launch with confidence.
Email finders return guessed addresses, and a large share never existed. Sending to them drives hard bounces, and a high bounce rate damages your sender reputation and inbox placement — sometimes after a single bad campaign. VerifyFlow assigns every found address a SAFE, PROTECTED, RISKY, or DEAD verdict so you cut the bounces before they happen.
Upload the emails you found and get a clear verdict on every one. No card required.
