This is quite confusing coming from Google.
The Inbox is attractive and easy, so what I thought was going to happen was eventually they (google)
would at some point adopt it as their main e-mail platform.
That never happened so I was at a loss as to what the purpose was.
It could be that it was designed to be an attractive alternative to their bland UI ?
Purely cosmetic, but if so then why not phase it in after so long ?
Protonmail is my "go to" now but I too had many questions for google about this in the past.
