Mailbox focused on emptying the user's inbox and favored using folders instead of leaving emails in the inbox. For instance, it incentivized the user with visual cues and gestures to organize emails based on priority and due date to empty to inbox.
Mailbox was limited to Gmail and iCloud accounts. It also supported Yahoo! Mail for three days.14 Setting up Mailbox required granting the company's servers access to the user's email account, either through APIs (Gmail) or direct access (iCloud). Mailbox's servers repeatedly queried the user's email account to provide push notifications and allowed the application to refresh its content without having to run in the background for prolonged periods.
