After editing an email delivery, what should you do if nothing happens in the preview tab?

Selecting a recipient profile is essential for displaying the correct preview of the email delivery. The preview tab functions by using sample data from specified recipient profiles to generate a realistic view of how the email will appear to actual recipients. If a recipient profile has not been selected, the preview may not render correctly, resulting in nothing appearing in the preview tab.

This step ensures that personalization, such as recipient names or other specific information, is applied, allowing the sender to fully see how the email will look to different segments of their audience. Without this action, the preview feature is unable to showcase the intended dynamic content and may leave the user with a blank or incomplete view.
