I would really love this feature. I dislike being pinged for a newsletter or my daily news. I only keep my notifications on for important emails like job applications, security alerts and two-way conversations/replies. But then I also want to know which emails i haven't read when going onto my email, so the custom filters wouldn't help. Right now macrodroid (automated, custom scripts) or some notification manager is my only option, I would need to filter out client side. Also I don't have sender information in my notifications for security, so I would have to filter by subject and start of email body.
