There isn't a way to completely delete messages from your Clearstream inbox, but you can mark them as "done." A message marked as done will be moved from its current folder to the Done folder, which you can view at the top of your inbox beside the Open and Unread folders.
To mark a message as done, just click Mark Done in the upper right-hand corner of any subscriber thread.
If this person responds again, their thread will reopen and be moved to the Unread folder until it has been viewed.
