Mailbox, now a part of Dropbox, is a mobile-first inbox that makes processing messages on your phone fast and delightful. It’s how email on the phone should work: Mailbox checks your mail from the cloud and delivers it to your phone with lightning-fast speed. A colorful swipe-based UI makes processing easy, and the “snooze” feature lets you put off messages until later. Currently available for iPhone and Gmail.
Mailbox makes getting to inbox zero - and staying there - a breeze.
