Abstract: Determining interest in promotional content to be displayed at a mobile communication device is described. The promotional content, including a first portion that is visible and a second portion that is hidden in a first state, may be received. The first and second portions are each selectable only when visible. A promotional display that includes the promotional content in the first state is generated. Upon receipt of a first input from the user in relation to the first portion, the promotional content may be transitioned from the first state to a second state such the first portion becomes hidden and the second portion becomes visible. Upon failing to receive a second input from the user in relation to the second portion, the promotional content may be transitioned from the second state to the first state. Upon receipt of the second input, an interest in the promotional content may be indicated.

Abstract: Systems and methods for clustering electronic messages are disclosed. In some implementations, a method includes, at a computing device, responsive to a determination that a message body of a first electronic message satisfies a set of content-based clustering rules associated with a first message cluster, assigning the electronic message to the message cluster. A cluster graphic is displayed for the message cluster. The cluster graphic is characterized by (a) a first state in which messages in the message cluster are individually depicted and (b) a second state, which replaces the first state upon user input and collectively represents a plurality of messages in the message cluster. Each message in the message cluster is either (i) addressed at least to a first recipient or (ii) originates from the first recipient.

Abstract: Systems and methods for clustering electronic messages are disclosed. In some implementations, a method includes, at a computing device, analyzing content of a first incoming electronic message against a first set of content-based clustering rules associated with a first message cluster, without regard to content relatedness between the first incoming message and any messages previously assigned to the first message cluster. In some implementations, the method further includes, responsive to a determination that the first incoming electronic message satisfies the first set of content-based clustering rules: assigning the first incoming electronic message to the first message cluster, and formatting for display, in an electronic message folder, electronic messages in the first message cluster as a first single cluster graphic.
