If you're on desktop: Hover over your username in the top right corner --> Click Preferences --> Unclick "and receive email notifications of replies" under Options
To the left of inbox is an invisible link to your profile. It’s there when I’m on my laptop but invisible on my iPhone. But click on the black part and it works.
so I tried this because I noticed some in my promotions folder...and now I'm still getting them AND getting notification pop ups for them on my phone
