ZeroBounce is a leading online email validation system created to ensure that companies sending complex and high-volume emails avoid deliverability issues.

More Details

ZeroBounce’s system reduces invalid, abusive, complaining, inactive, and spam-trap email addresses to keep your emails from being flagged, damaging your sender bounce rate, and ruining your sending reputation.

The platform also includes a set of deliverability and list enhancement tools, including an email server tester, an inbox placement tester, a blacklist monitoring tool, and an activity data tool that detects subscribers who have had email activity in the last year.
