Inbox by Gmail launched in 2014 with the intention of fast-tracking some unique features to adventurous, mobile-first users like attachment content previews in the list view, auto-generated Smart Replies or priority tags for certain senders.

Unfortunately, Google looks to be shutting down the test lab as it mainlines more features to Gmail. Inbox will be deprecated at the end of March next year. Fortunately, because Inbox requires a Gmail account to use, all the messages in their Inbox account are also still on Gmail. Same email address, same password.
