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.

I have a healthy email list, but will I reach the inbox? Test every new email message before you send it

Our free bulk email validator helps you identify harmful contacts on your list. However, removing them does not guarantee you’ll reach the inbox. Subject lines, content, and email server configuration can impact deliverability.

Don’t wing it with a new email campaign. Use the ZeroBounce inbox placement testing tools to determine where your emails will go before publishing your email campaign.
