Abstract: A three-tiered content notification system that trifurcates the content notification system into a message consumption component, a message filtering component, and a message delivery component. The message queue comprises content published to an event application programming interface (“API”) for the content notification system. By generating this queue of available content, the message filtering component may apply a batch filter on the available content as opposed to conventional per item filtering. During batch filtering, filtering criteria may be applied to all content currently in the queue. The system may rank this content such that only the highest priority and/or relevance ranking may remain in the batch. Content that is not filtered out by the system may then be sent to the message delivery component. At the message delivery component, the system may select delivery channels for the remaining content.
