How are you using partitioning? What's working well and what can be improved?

I am working with a client with more than 1000 agents who need privacy on marketing emails at the user level. Instead of managing individual emails, it would be great to be able to put emails into folders and then be able to manage the access to the folder itself.
P.s I know you can assign marketing emails to folders AND that you can manage access to individual marketing emails, but you cannot manage the access to a folder currently :slightly_smiling_face:
