Create contact lists
A contact list is a collection of email addresses, and is useful for sending email to a group of people. Contact lists are sometimes referred to as distribution lists.
For example, create a contact list named My Book Club and add all the members of your book club to it. When you want to send an email message to everyone in the club, just enter "My Book Club" in the To line of the email.
By default, contact lists are created in the default Contacts folder, and you can also see them under Your contact lists. If you want to save the contact list in a different folder, select the folder before you select New contact list.
