lemlist Email Verification
Verify lemlist prospects before your campaign. Connect your lemlist account, verify every email address, and push clean results back, all automatically.

How It Works
Four steps to a clean lemlist database.
Connect lemlist
Paste your API key once to connect. No password sharing.
Import contacts
Pull contacts or lists from lemlist. Duplicates are removed automatically.
Verify every email
Each address runs through the 9-point engine including SMTP mailbox confirmation, catch-all and disposable detection.
Push results back
Clean results sync back to lemlist. Invalid contacts are tagged so you can exclude them from campaigns.
