A useful feature for a service like this is being able to set delegates both from the producer and consumer side. For example, if the person I sent the notification to doesn’t respond in <time window>, then send a request to this person (potentially their manager / emergency contact / etc...) . And, as someone receiving notifications, set another person as my delegate for a certain time window and for a specific application. This is what we have to deal with to handle OOO scenarios.
