I don't know how many people here use Inbox by Gmail but I find it miles better than the standard Gmail website and app. It's better at organizing, makes it easier to bundle things, automatically makes a "trip" for you when you get a flight/hotel/car reservation, and adds any subsequent related email to it, has a much nicer and better UI than Gmail IMO. Unfortunately, it seems like Google is discontinuing in this coming March. Apparently, Google is planning on adding a lot of the functionality from Inbox to Gmail but we'll see when that actually happens. Gmail for me is just way too cluttered and displays way too many random emails that I don't need to see on my main primary tab, Ibox solved that and has been a joy to use. I'll miss it and I'm more than a little annoyed that it's going away, it's just so good at automating my inbox that I rarely have to move or even delete anything, I see what I need to see and don't see what is not important. Hopefully, Google does a good job continuing to update the old Gmail interface and a lot of the good parts of Inbox will make their way to Gmail. You can read more about it here
