A contextually sensitive user interface for defining an e-mail message handling rule is provided. The user interface includes one or more user interface objects for specifying conditions for the rule and one or more user interface objects for defining the actions to be performed if the specified conditions are met. The conditions that are displayed within the user interface for selection are chosen, at least in part, based upon the context in which a request to create the e-mail handling rule is received. The displayed conditions may be based, in part, upon the contexts of reading an e-mail message, creating an e-mail message, creating an alert subscription, or selecting a user name.
