Many were surprised to see that Gmail was not on the massive list of products Google updated during their recent I/O developer conference. It looks like Gmail was up for a refresh after all, but Google chose to give it a stage of its own.Google’s popular email client is a difficult thing to change all at once. Email is one of those things that people think they really would prefer stay exactly the same… until they see something better. As a result, most of Google’s changes to Gmail offer the ability to revert back to previous designs for a period of time.This latest update is across the entire platform, affecting the web version of the apps as well as the mobile versions for iOS and Android simultaneously. Reverting back from this update isn’t a likely option for long, though it is hard to see these new changes as anything but positive.If you can rely on Gmail for anything, it’s correctly filtering your messages. Spam emails in particular, but also personalized message filters work with incredible accuracy on Gmail. Google wants to add a layer of context to Gmail, and break your inbox up into relevant tabs. You can view your entire inbox if you choose, but you can also sort by categories now.If you’re a heavy social networker who hasn’t already disabled every kind of email notification from your network of choice, you can now sort all of those messages in one place. Promotions from places like LivingSocial or Google Offers, where you know you get them every day but don’t really need to see them every day, get sorted into a different category. There are several options to choose from, and you can align them as tabs across the top of your Gmail to use as you see fit.Google makes sure that you can revert back to any other inbox style you wish, but lets the rest of us know that soon you’ll see a gear menu in your Gmail that will allow you to configure your Gmail tabs as you see fit. That configuration will sync with your iOS and Android Gmail clients, and allow for new organization across your entire email experience.
