How Do I Use Email Aliases In Mac Mail?

If you have one or more email aliases configured under your mail box, you can use the following procedure to send email from all of your addresses and aliases.

Note: An alias email address is an account in which all email sent to it automatically goes to a master email address. This is not the same thing as having different email addresses that aren't automatically tied to a central address.

  1. In Mail, choose Preferences from the Mail menu
  2. Click Accounts
  3. Select your master account (the one to which email from your alias addresses gets sent)
  4. Click Account Information and in the Email Address field, add all of the accounts associated alias addresses, each separated by a comma
  5. Save your changes

Now when you create a new message you can select one of the aliases from the account pop-up menu in the new message window.
