    Redirecting emails when testing

    When developing and testing, you need to ensure that no email gets sent to your customers by accident.

    To redirect all emails to a list of test users, check the Redirect Emails to Test List. Add the email addresses to redirect the emails to, in the Test List Addresses field.

    List of the test email addresses

    In this example, all emails sent from this environment are redirected to an internal mailing list, instead of their original address. Note that all emails are redirected, including emails addressed using the CC and BCC fields.

    Configure the Environment Hostname

    To ensure the links in your emails point to the right environment, be sure to set the environment hostname.

    Navigate to the Administration tab and click Environment Configuration. Set the Hostname field with the domain name you want your users to navigate to.
