Delete a Subscriber List
If you no longer want to use a subscriber list, you can delete it. This action does not delete the subscribers on that list, but it does remove the list itself so that no further sends can be conducted with that list.
When you delete a subscriber list, your account also loses all tracking information related to that subscriber list. For this reason, Marketing Cloud recommends leaving the list intact and creating new lists via new opt-in procedures.
