We get it - your inbox if full of a lot of stuff. That's why we divide the types of emails we send into easy categories, which you can control from your Settings page.
To select which types of emails you'd like to receive - and which you wouldn't - just click your profile icon at the top of the screen, then Settings.
On that page, head to your "Name, email and notifications" tab.
There, you'll see a section called Notifications where you can choose the types of emails you want in your inbox.
