Only System Administrators and Lists Managers can configure notifications about updates to the list. List Administrators can configure the notifications of any lists to which they have been assigned. To configure the notifications for a list, go to the left sidebar and click on the “Collaboration” button > "Lists" > select the relevant list > go to "Notifications" > choose between "Disabled", "Notify everyone in the audience" and "Notify only subscribers from the audience". If you choose “Notify only subscribers from the audience” additional fields will appear requiring you to add subscribers and mandatory subscribers. When you are ready, click on the “✓” button.
