AppleInsider was able to take an advanced look at Mailbox last month and found it to be a solid addition to any email workflow.
The app's unique interface allows users to turn a Gmail inbox into a type of "to-do" list, where each message can be "snoozed" for later perusal.
For example, if an email isn't urgent, but will require action the next day, a user can select the "tomorrow" snooze, which will move the message out of the active inbox and return it the next day. Snooze time settings are fully customizable.
The iPhone-only app features swipe gestures reminiscent of to-do app Clear, with users being able to swipe left or right to activate snooze timers and send message strings to the archive folder or a customizable lists folder. Emails can also be deleted with a longer swipe.
Anyone can download the app for free from the App Store, and those users who pre-registered can enter their reservation numbers for first-come, first-served account activation. Those who have yet to sign up can do so in-app, while all users can watch the reservation line in real-time.
