Null Bounce

Null Bounce is an email validation tool that helps companies decrease the bounce rate for email campaigns. Also, the service is available as an API, which can be used, for example, on sign-up forms to ensure that user submits a valid email address.

To verify each email, Null Bounce uses several different methods, including SMPT-validation and some provider-specific methods. Role-base, disposable, and free emails are detected as well. All duplicated emails are free.
