Technologies are provided for generation of composite messages using qualifying events corresponding to respective ticketed performances and qualifying actions of a subscriber of a service platform. By analyzing qualifying events and qualifying actions jointly, the disclosed technologies supply a number of contextually-relevant individual messages collected in a composite message that is delivered to the subscriber periodically. The individual messages describe ticketed performances that are relevant to the subscriber. The composite message also provides reasons for the inclusion of the individual messages in the composite message. The individual messages can be arranged within the composite message according to a layout based on a ranking of priority scores. Each priority score conveys a level of relevancy of a ticketed performance with respect to a subscriber. The provided technologies, therefore, supply a composite message that can match the subscriber to personalized ticketed performances while reducing the number of messages received by the subscriber.
