Updated Gmail Will Sort Your Email
Google isn’t doing away with the main Gmail inbox – that’s still there, in the form of the Primary tab. You can direct any mail you want here, but unless you choose otherwise, social network-related updates will drop into the Social tab, while the endless deluge of grey mail (offers from companies that you OK’d for email at one point or another and from which you keep meaning to unsubscribe) goes straight to the Promotions tab. Helpfully, all receipts and such go in your Updates tab. As always, Google is promising plenty of customization options.
