This is a handy app to manage groups, something that cant be done with Apples stock Contacts app. This makes it easy to add or edit group members, create new groups, and email or SMS members of a group.
One feature Id like to see is the option to exclude yourself if you happen to be emailing a group which you are a member of (work contacts, for example). Also, it would be good if you could specify which email to use if a contact has more than one email or phone number.
