Hi there,
Incredimail is a free mailing software that allows you to have the following :
-Vibrant Incoming Email Notifications
-Cool 3D effects (sending, receiving and deleting your messages)
-Variety of backgrounds, animations and sounds
-Animated Emoticons , to enliven your text
-Personal signatures
-Personal voice messages
It also has an Online gallery where you can download new graphic content.
You can still use your AOL mail, if AOL mail has pop3 facility, you can send-receive AOL mail through Incredimail, as its just a mailing software and not a free-paid email service.

Hope this helps. Thanks !
