Uptime: Email Notification

I use Uptimon my website and the new version is great.
However, i receive a lot of Notifications it is quite Spammy. It could be great if we could set a minimum time of Downtown (eg. 1 or 5 min) before receiving an email alert.
It would be less stressfull not to receive an alert while serveur restars or plugins updates briefly.
Is it possible, if not you may think of it.
Thanks again for your great job guys
