Systems and methods for presenting an in-application message to a user of a software application make use of trigger events that occur on remote servers. When a remote server notes a trigger event, the remote server sends information about the trigger event to a customer engagement service. The customer engagement service causes a push notification to be sent to a user's computing device that is running a software application. The receipt of the push notification causes a campaign within the software application to log a trigger event, and that logged trigger event causes the campaign to present the user with an in-application message.
