What is the question? If you are looking for a way to reply to the sender in case of failure, instead of timeout, you need to catch the exception in the EmailServiceWorker and reply from the actor.
An alternative would be to reply from the supervisionStrategy in the parent actor, but that requires that you keep track of the original sender there.
