It is imperative that there be a separate/different subject line when a computer is unavailable, and also that it indicates how many computers are involved. This is basic for any RMM and is a huge flaw in your service. For those of us who have a lot of customers/machines, there are a lot of emails that come in daily and it is way too easy to miss ones as critical as unavailability. It cannot be that difficult to have those go out with a different subject line, or even allow for text notifications under those circumstances.
