Inactive messaging and deleted recipient lists

When you delete a recipient list that is referenced by an inactive messaging, the system removes the list immediately. The list is no longer available for reference by any other messaging campaign.

An inactive messaging is a messaging campaign that is not actively processing messages, preparing to process messages, or waiting to process messages. For example, a messaging is considered inactive before you start the messaging run. It is also considered to be inactive after the messaging run completes successfully.
