Rules allow you to move, flag, and respond to email messages automatically.
The easiest and most common rule to create is one that allows you to move an item from a certain sender or with certain words in the subject line to another folder. You can create this rule directly from a message you've already received.

Notes: After you make a rule on your computer or Outlook.com, it's saved and applies on other Outlook platforms. If you belong to a listserv, consider replying to the sender, rather than “reply all.”
