Mailbox
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
Mailbox was an iOS email client developed by Orchestra, the startup founded by Gentry Underwood. Launched publicly in February 2013 after a famous waitlist beta that drew over 1.5 million signups, it reimagined Gmail with swipe gestures to archive, delete and snooze emails. One month after launch, Dropbox acquired Mailbox for a reported $100 million, making Underwood its head of design.
02 / Mailbox FAILURE REASONS
Failure reasons
Inside Dropbox, Mailbox stalled: development all but stopped, rivals like Google's Inbox copied its signature swipe gestures, and Underwood quietly left his role as head of design. Dropbox decided to refocus on its core collaboration product and, on December 7, 2015, announced it would shut down Mailbox (and the Carousel photo app), acknowledging there was only so much an email app could do to fundamentally fix email. The app went dark on February 26, 2016.
