​​It's often situation when You need to temporarily disable alerts on Your on-premise SharePoint portal, but there is no standard ability to do it in simple and handy way.

So I created this Alert Manager, that allows You to list/temporary turn off all alerts from current web in one click. Same to turn them back on.  

 ListUser nameFrequencyStatus
Or another webpart, which allows You to manipulate multiple alerts at once( this example will not subscribe if You are not logged in, because domain-controller is not configured to allow anonymous queries):
  1. Select user form picker
  2. Subscribe or unsubscribe user
  3. Check subscriptions status pressing "Display" below
