Many of you probably use Gmail as its quite popular account which people use to open their email accounts. Just recently they have changed the look of the inbox, and emails have been put into categories Primary, Social and Promotions. I think this is quite good, because sometimes you get so many promotion emails that you spend most of the time deleting them and not actually getting enough time to read your other emails. And if you want to search for any social media emails then you easily find them. You can also add two more tabs into inbox, which are updates and forums.
