• receiving data indicating a level of user engagement with a messaging application for a given user;
• determining that the level of user engagement is below a specified threshold;
• prioritizing a plurality of events, associated with the messaging application, for transmission to a client device of the given user in response to determining that the level of user engagement is below the specified threshold;
