Audiences allow you Control Access to Email Folders. By adding an audience to a Folder, you are limiting the access of that Folder's content to those assigned to the right Audience. When you Import Employees you must Add People to an Audience. When an employee's Audience matches the Folder Audience, they can receive emails from that Folder. Use the instructions below to Delete an Audience.
To Delete an Audience:
Go to the People area and click 'Audiences'.
Note: If you do not see the Audiences option, you are using Simple Audience Management.
Click 'Delete' beside the Audience name.
Click 'Delete' to confirm the deletion. The Audience will no longer appear in your list of Audiences.
