EasyTS
EasyTS is a simple to use interface to manage your client e-mail messages. From one interface you can view all of the current messages your clients have sent you, reply to them, and keep track of the entire correspondence. EasyTS supports multiple users so you can have several people processing your client e-mail messages at once. Your clients will be able to use their normal e-mail programs to contact you, and won't have to create a special account through a web-based interface to correspond with you.
