Systems and methods of storing a message directed to a user and delivering the message from a network server to a user's client device provide for receiving the message and storing the message to an access-restricted user-specific message storage area. When an access request from an application program executing on the user's client device is received via a packet switched network in accordance with an Internet protocol, a determination is made whether to grant or deny the access request. If the request is granted, a link is provided to the user, wherein selection of the link causes the message to be transmitted to the application program via the packet switched network in accordance with the Internet protocol.
