Deleted lists referenced by multiple messaging campaigns

A single recipient list can be referenced by more than one messaging. The effect of deleting the recipient list on the messaging campaigns depends on their current state.

When you delete a recipient list that is referenced by multiple messagings, all of the configurations change to indicate that no recipient list is selected. If one of the messaging campaigns is currently active, Deliver designates the recipient list as retired for the active campaigns only.

No other messagings can use a recipient list after it is retired. When the active messaging that references the retired list completes its messaging run, Deliver finishes removing the recipient list from the system.
