Just a day after rolling out an updated app with several new features and enhancements, the team behind popular Gmail management app Mailbox has announced that it has removed the reservation system that had previously left some interested users waiting up to several weeks to gain access to the service.Good news! Mailbox is now available without having to wait in line. After 10 weeks of around-the-clock hard work, our engineering team has scaled the Mailbox service to deliver over 100 million messages per day (and growing). We believe we can now confidently handle new users as they sign up, so we’ve pulled down the reservation system.
