This was a question brought up in the Kpop Survey so I wanted to show you how to switch up your settings :D
I'm on iPhone but it should be similar on Android^^
1. Go to your profile and hit the setting gear (where the squirrel butt is!)
2. Set the notifications you want you can turn off email for some, or have certain things be only to email etc!
The last one "Personalized content recommendations" is the notification Vingle sends that is often breaking news or cool content you missed :D
