A method of processing messages executes at a computing device having one or more processors and memory. The memory stores one or more programs configured for execution by the one or more processors. A first message for a user is analyzed for a structured content element. When found, content from a data source distinct from the message is obtained by executing an associated action. A first message display state is formed for the message comprising a message notification and the content. A messaging application user interface, comprising an electronic message list with a plurality of objects, is updated. Responsive to selection of a first object of the plurality of objects, the first object representing the first message, the user is enabled to toggle the first message display state between first and second display states, the second display state differing from the first by providing direct access to the first message.
