Currently, the reservation list for Mailbox, a third-party iOS e-mail client for Gmail, is about 570,000+ people long. But if you have the patience for it, this user-friendly and polished app is worth the wait.
Swipe gestures are heavily employed with Mailbox. To organize your e-mail, the app uses five "zones" of categorization. Swipe an e-mail quickly to the right to move it to the archive zone (left). Swipe a message swiftly to the left and you'll move it to the "snoozing" zone. To "snooze" your entire inbox and deal with these messages later en masse, scroll to the bottom and swipe to the left (right).
Another feature in Mailbox that makes mobile e-mailing smoother is the ability to quickly attach a photo when composing a message. When you want to write a new message, an e-mail draft with a small camera icon on the bottom right pops up. Tap on it and you can choose whether to attach a photo from your gallery or snap a photo from your camera.
You can do away with e-mails a revisit them later by sending them into the "snooze" zone. Choose when to deal with them with eight different options (left). These terms can be tweaked by you, so you can set exactly what Mailbox means when you want to deal with an e-mail "this evening" or "someday."
