Contacts Groups Free

This app allows the user to create multiple groups of contacts from the existing contacts app. The user can sort contacts into any of the groups and can then easily broadcast emails or SMS text messages by simply selecting the group, typing in the message, and pressing the send button. This free version allows up to 10 groups and 10 users per group. The paid version allows unlimited groups and unlimited contacts per group.
This is a Very Cool App.

Note: To delete a group you simply need to place your finger on the right part of the screen next to the group and swipe the screen to the left. This will open up the delete button. Simply tap the delete button and the group will be deleted.

Note: MSExchange servers are not currently supported by Apple to allow for group creation. As a result, this app will not function correctly if your address book is synced with Microsoft Exchange.
