4th Office moves unimportant emails from your main inbox into the Muted section. But don’t worry – you can still see all your muted emails.
To stay ultra-focused on the important stuff, you can also mute contacts who you don't want distracting you. They'll hang around in your Muted section and you won't receive notifications about them.
When you want to un-mute a contact, find them in Muted and, with a swipe or a click, they're back!
