If you constantly find yourself CC-ing the same group of people you may want to form an email group to make composing and sending emails faster. Just like the name applies, you associate several emails together to form a group address. A good use for group emails are situations like a new development team or department.
To form a group address do the following:
1. Go into Address Book.
2. Wheel click and New Group.
3. Enter the name of your new group address.
4. Add people to your group and Save.
