Disable notifications of some emails I daily receive many emails. I need a better control of emails. I want to disable notifications of some emails. A notification means for me that my phone vibrates and my smart watch vibrates. To filter those messages out of my inbox is not a possibility because I want to review them later. I think smartly disabling notifications of some emails would be great. Sometimes, I receive 30 emails in a row from one sender, for instance, what I do not want i.e. 30 vibrations in your phone and/or smart watch. I would like to have a feature that: 


disables notification for 3 hours if more than 2 emails received in one hour from one sender; and
disable notifications for 3 hours if two emails received in 5 seconds from one sender. 


How can you disable notifications of some emails in Android 6.0?
I find the plugin Do Not Disturb and its Now mode more robust than eNotify because it is will disable all notifications of all applications by one button. However, it cannot do it for some applications only. I think eNotify could work for that but do not like its cost, its appearance, ... Its userbase is too small to get my trust.
