If I want to know about a new email, group message or some other random thing I'll open the app or site and take a look.
Otherwise leave me the ** alone.
I for one stopped using email push ony smartphone when my hosting provider started sending out invoices at 1am. Who thinks that this is a good idea?
In the early days of Android there was an app which was able to set my phone to silent based on nearly unlimited inputs, like location, time, app notification, weather, etc. The relevant API was patched out with Android 5 or so, one of the most stupid decisions ever.
It's more challenging to disable notifications we don't care about anymore with tactics like these.
