How It Works
Four steps to a clean Constant Contact database.
Connect Constant Contact
Paste your API key once to connect. No password sharing.
Import contacts
Pull contacts or lists from Constant Contact. 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 Constant Contact. Invalid contacts are tagged so you can exclude them from campaigns.

Lower contact costs
Constant Contact prices by contact count, so remove invalid addresses and pay only for reachable ones.
