    Once you enter your username and password you may be asked which account to authorize access. Choose an account you want to validate emails with and click Choose Account

    Choose the account you wish to authorize

  • Step 6:
    Once you have authorized access ZeroBounce will gather all of your email addresses for the account you selected during the authorization process.

    Choose one or more lists to validate/score. Click the validate or score button to start the process. Depending on how many emails you have to process it could take a few minutes to pull the lists and add them to our processing queue.

    Note: The results of the validation and scoring are automatically exported to the integration they originated from.

    After successful integration, you will be able to view your lists in your ZeroBounce Dashboard.

    There is also the possibility to share your contacts between integrations, schedule scoring and validation or monitor your contacts to validate any new contact automatically. To learn more about this, check out this dedicated page: Integrations Contacts Monitoring, Scheduling and Sharing.

    To automatically validate individual files within the integration, you can enable Auto Validation for each file directly from the list, under Auto Validation. This can be selected for All Contacts, and in this case all of the contacts will be auto validated or, select only the desired lists for which the auto validation should take place.

  • Step 7:
    You will be taken to the Email Validation Results page which will show the list you selected in queue.
