Create larger groups more quickly
To save time when creating a group with many members, you can simply add other group addresses to the members list. For example, if want to create a new group for all the sales persons in regions A, B, and C, and you've already created separate groups for those regions, just add, or "nest," the three region addresses as members of your new group.

More easily maintain group memberships
Another advantage of nesting groups is that you can more easily maintain group memberships across multiple groups simultaneously. For example, you can create several smaller groups that contain members who typically receive the same types of communications, such employees in the same departments or teams. Then, use these smaller groups to build larger groups. That way, if you need to add or remove the same member from multiple groups, you can edit just the one smaller group to which the member belongs. All of the larger groups of which that smaller group is a member are updated automatically.
