Automatically Add Email Addresses in Mail

When you’re reading messages in Mail, you can automatically add someone’s email address to Address Book simply by typing Command-Shift-Y. And once you create a group address in Address Book, you can add all of the group members simply by type the group name in the To (or cc) field in Mail. Here’s how:

1. Go to Address, click the + sign below the Group column, and give your new group a name — “Tennis Team,” for example.
2. Click “All” at the top of the Group column (so the name of everyone in your Address Book appears) and drag the names of everyone on the tennis team into the new Tennis Team group.

And you’re done. The next time you want to send email to the team, you won’t have to enter each name one at a time. Just start typing “Tennis Team” and let Mail fetch and fill in all the email addresses for you.
