Address Book Grouping
You can "group" addresses within your address book by clicking Add New Group.
This feature allows you to have a specific group of addresses that you need to either access quickly or send multiple mailings to the same group of addresses. For more information regarding the Address Book feature within your LetterStream account, you can click here.
You can also delete an address group by selecting the group and then clicking the blue Delete Group button that exists below all of the addresses within that group.
At this time, an existing group cannot be re-named.
