What is 'Focused Inbox'? Emails that are considered personal and not part of commercial or soclal campaigns. In the Google world, the items that would appear in your 'Primary' tab. Or, officially:
Focused Inbox works across all your email accounts, personal and professional. To create an inbox that "feels right" to you, the system takes into account emails and contacts with whom you interact, and filters out noisy sources like automatically generated or bulk email.
