Hi,
At this time you have two options. The first one is to sort your user list on the fields Active or Unconfirmed. You might nee to chenge the order of the list to Ascending or decending.
The second option you have is to create a seperate list and run a mass action to subscribe all inactive or unconfirmed users to this seperate list. A mass action is a manual action that runs once. If you want to do it automaticly you can setup an Automation for that. (To use Automations you would need the Enterprise version)
