Anyone know how we can mange to tune the notification rules, to not send request updates when a request is closed?

Scenario:

I respond to a request, then closes it.

Since we have notification on both request update, and when a request is closed, this will generate 3 emails:

Mail 1) the one I sent

Mail 2) Request is closed

Mail 3) the request has been updates.

This is just messy, and confuses the users since they get 3 emails, where the third email is just spam/junk.

Is there any way to fix this, go around the problem etc? We need to have both the notifications turned on, but we don't want to send out request updates after a request is closed.

Looking forward to your answers.

Kindly Regards
