Labels, folders, Move to and Mute
Labels sort conversations without moving them, as in Gmail. A conversation can have several labels, and each label has its own view under Labels in the menu on the left.
- Open a conversation, or select some in the list, and press the tag (or l).
- Tick the labels you want and press Apply. Type to find a label; press Enter to use the one that matches, or to create a label with a new name.
- Click a label on a conversation to see everything with that label; the × beside it in an open conversation takes it off.
- Make, rename, recolour and delete labels with the + beside Labels, or under Settings → Labels. Deleting a label takes it off the mail, never deletes mail.
- Labels are saved on your mail server as tags (IMAP keywords), so Thunderbird and other mail apps see them, and tags those apps set show up here as labels.
- Search with label:name (a dash for a space, as in label:project-x).
Move to (v) moves conversations to another folder of the same account. Type to find the folder, then press Enter.
Drag and drop, as in Gmail: drag conversations from the list onto the menu on the left. On a folder they move there (a folder of their own account); on a label they move there from the Inbox (elsewhere the label is added); on Inbox, Starred, Snoozed, Spam or Trash they go there. Select several first to drag them together; Undo takes it back. Drag a label from the menu onto a conversation to put the label on it. With several accounts, Folders lists the folders of the account you are in (with All accounts, every account's, each with its colour).
Folders of your own: New folder (the + beside Folders, or under the chosen account), and on a folder its ⋯ menu: Rename, New folder inside (folders can sit in folders, and in Archive) and Delete. Deleting moves the folder's mail to the archive first (Archive, or All Mail in Gmail), so no mail is deleted. Inbox, Sent, Archive and the other standard folders stay as they are. Beside a folder: its conversations, and in brackets the unread ones.
Mute (m, or More → Mute) stops a noisy conversation from coming back: it is archived now, and new replies go straight to the archive instead of the Inbox. Find it again under All mail, in search, or with is:muted. Unmute, or moving it back to the Inbox, ends it.
