It's important to remember that email lists do not have to be deleted, unless your organization would like to. If you would like to delete a list, please follow the steps below: 
  1. Log in to the NetCommunity site
  2. Click Email > Lists 
  3. Click the red 'X' icon next to the list that you want to delete 
Note: If the delete button is missing, the list has been used for a message previously. Other steps will have to be taken prior to deleting the list
