Great integration with HubSpot
Simple integration with HubSpot. You can select all your contacts for verification, but I prefer using lists.
Verify contacts before sending emails
- Simple and easy to use. - Good report without frills.
You can't remove bad contacts directly from TheChecker. Download lists and upload it to remove or add to opt-out.
