They claimed that everything you like about Inbox has been integrated into Gmail, but it just isn't the same. All of your email categories/bundles were on the landing page. It was super intuitive to click into them and dig down into the hierarchy, and to go back/up a level on any screen you just scrolled to the top or bottom of a screen and overscroll (like a pull-to-refresh type move). I didn't have to pull out drawers or actively jump between categories. It was perfect.
Now with Gmail I have to click into my email categories one-by-one to see what's in each of them. It doesn't do the automatic bundling. And GOD the ads! Which there are not only way too many of, but they're constantly asking me if I find them useful or not. Of course I don't find them useful, I'm trying to check my email.
Do you have any metrics to support that? I haven't met a single person who disliked Inbox.
Most of the good features are already baked into GMail and Outlook already. The extreme white space Material Design look is already way out of date.
The key feature of having AI monkey with the inbox is a non-starter if you might face consequences for the AI getting it wrong. Even something as basic as Focused Inbox in Outlook causes problems and it’s only got two categories. The base gmail experience is super bad at its own implementation of categorized mailbox.
It was too beautiful for this world.
Inbox wasn't killed for lack of users.
Hangouts, Inbox, and most of Google's prior messaging platforms were terminated due to lack of centralized data-gathering of the most important data sets.
This is old news though.
