Email Notification for all Incidences (Service Down)

If any service going down need to get an email notification on who all enabled it, whether the impact is less or high. I have contacted RingCentral for the solution, they said if the impact is less (less than 1 hr) they will not send a notification, logically it is not the correct approach, We cannot predict the impact and how far it will affect our environment, So whenever the service going down should get the email notification. Please let me know is there any possibilities.
