Mac Mail Rules and Filtering
You can set up rules to filter incoming messages or reorganize messages you’ve already received. You can have Mail automatically perform actions, such as file, forward, or highlight a message, based on conditions or criteria, such as the message’s sender, recipients, subject, or content.
- Click on the Mail menu and choose Preferences.
- In the Preferences dialog box, click Rules.
- Click the Add Rule button, and name the Rule.
- Set the appropriate conditions and resulting actions. To specify multiple criteria and actions, click the Add (+) button.
