Labels
A label is a tag on top of folders: a message stays in its folder and can carry any number of labels. A mailbox can have up to 30 labels, each with a name and one of eight colours.
- Put labels on mail with Labels in a message's actions, in the list's right-click menu, or with the L key.
- The left column lists your labels under the folders. Choosing one shows every message carrying it, from all folders except Junk and Trash.
- In the search box, label: followed by the name finds the same messages.
- Other mail apps see labels as message flags, and a label stays on a message when it is moved.
Filter rules
Filter rules act on new mail as it arrives. Manage them in webmail under Settings → Rules & forwarding. A mailbox can have up to 50 rules, applied in order.
- Conditions (all or any of up to 10): the sender; the To or Cc recipients; the subject; a named header; a size above a number of KB; or having an attachment.
- Actions: mark as read, star, apply a label, forward a copy (to at most 3 addresses), move to a folder, delete, or stop processing later rules.
- Rules can be disabled, reordered and edited. They do not touch mail that has already arrived.
Auto-reply
The auto-reply answers incoming mail while you are away. In Settings → Rules & forwarding, turn it on, optionally set a start and an end, a subject and the reply text. The same sender is answered again only after a number of days you choose (1 to 30; 7 unless you change it). While it is on or scheduled, a bar above the inbox says so.
Forwarding
Forwarding sends a copy of every new message to other addresses and keeps the original in your mailbox. In Settings → Rules & forwarding, enter one address per line, up to 10; the mail server may allow fewer, and webmail then says so. It applies to new mail only. To change the addresses, turn forwarding off and enter the complete list again.
Blocked and allowed senders
Block an address or a whole domain and its new mail goes to Junk (or is deleted, if you choose so), with no forwarding, auto-reply or rules applied. Allow an address or a domain and its mail is never left in Junk. Each list holds up to 300 entries. Block sender and Always allow sender are also in a message's Sender menu and in the list's right-click menu, with Undo.
