The present invention relates to a system and methodology to facilitate automated delivery of notifications according to various applications that can be employed with the framework of a notification platform. The applications are described by models that enable users to easily/conveniently interact with the notification platform. The application models can be incorporated within and/or associated with the notification platform. Moreover, the models can be employed to enhance subscription experiences for users, whereby users can easily and economically subscribe and unsubscribe to one or more notification services. In addition, subscriptions can be dynamically adjusted based upon explicit commands from the user, inferred from contextual user states, and/or based upon incentives or other factors directed to the user.
