You can add multiple labels to a message, and adding a label does not move it from the folder it is stored in (for example, your Inbox ).Ĭustom labels and folders are shown in the left-hand sidebar of the web app or when you tap the Menu (hamburger) icon in our mobile apps.

Labels are simple tags you can add to messages to make them easier to find or to apply filters to.Each message can only be stored in one folder (in addition to the All mail and Starred folders) at a time. If you move a message into a folder, it is removed from your Inbox. Folders are containers for your emails.ProtonMail uses a flexible hybrid system of folders, subfolders, and labels to maximize productivity and organization within your inbox.
