Score

How active are my contacts? Score each contact and discover which ones are the most valuable

Even with a valid email address, it’s tough to know how your emails will perform with a specific audience. Or is it?

ZeroBounce Score utilizes artificial intelligence to anticipate the activity levels of email contacts based on their history. A score of 0 indicates low activity, while a score of 10 indicates a highly-engaged email user. This is especially helpful for sorting out tricky catch-all emails on your email list.
