Where is the List Manager?
Note: The List Manager has been retired and replaced by Lists in the CRM. Here, you can upload, add to, delete, etc your lists as usual.
The List Manager is still available from the top menu. If you cannot see the List Management tab, you can add it to your menu by using the More tab. When you click on the More tab, you'll be able to access list management from there or add to the menu by clicking on the Add button.
