Disclosed are systems and methods for improving interactions with and between computers in content providing, searching and/or hosting systems supported by or configured with devices, servers and/or platforms. The disclosed systems and methods provide a novel framework that uses data related to users' personal, online and real-world activity, and inbox viewport information to identify messages that the users will interact with the next time the users view their inbox. Based on this, the user's inbox view can be modified so that third party messages can be situated amongst those messages (e.g., adjacent to or within n positions), so that the user will most likely view that message when interacting with the messages deemed important to the user. Thus, the disclosed framework provides mechanisms for message platforms, systems and applications to modify a user's inbox to strategically position messages from third party providers to capture the attention of the receiving user.
