An apparatus comprises a processing device configured to select a given notification to be delivered from a first computing device to a second computing device and to determine (i) first notification metrics associated with one or more previous notifications delivered to a set of one or more computing devices including the second computing device and (ii) second notification metrics associated with a current status of the second computing device. The processing device is also configured to provide the first and second notification metrics to one or more machine learning models, to identify recommendations for modifying delivery of the given notification from the first computing device to the second computing device based on output of the one or more machine learning models, and to modify the delivery of the given notification from the first computing device to the second computing device based on the identified recommendations.
