I'm not a fan of my email being categorized for me
I pretty much like all things Google, but Inbox just isn't for me. I much prefer good old fashioned Gmail on my iPhone. The way Inbox sorts my emails doesn't always make sense to me, and I suppose I'd rather sort it myself. There are definitely better email apps out there. I know because I've tried a bunch of them.
Awesome desktop and mobile usability and design. It helps you increase productivity with some really handy features that saves and organize.Cons:
There is not friendly way to attach and image and assign a link to it (there is a way but you need to dig and research on how to do it.
It took me just 4 days to get used to it coming from traditional gmail desktop tool.
But once I could manage the initial learn curve, it really improved my productivity specially with reminders, smart suggested answers and how it groups different kinds of emails automatically.Agustin Esperon has used this product for one year.
