Is it good thing? Gmail will completely control your users !! and your business in a way, how is it good thing? I would not want to show google how software works with user's emails, it is not Google's property, emails belong to users.
I'm not sure I understand what you're saying. Our users already use Gmail, we just built a service to help them clean their inboxes. We'll support other providers eventually :)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
