Deleting a List
You can delete list(s): Click on Contacts from the top navigation bar, a drop down menu will appear, click on Manage Lists and select the list(s) you would like to delete then click the red Delete Selected List Button, then click OK button (Once you delete a list it cannot be recovered)
This is especially useful for those with over 50 lists as deleting them will help optimize your system and speed up your work flow.
Deleting lists does NOT delete your opted-in subscriber from the account.
If you deleted a list on accident, you can just recreate the list and move your subscribers back into the list. Deleting the list did NOT delete the contacts.
