Swamped in email? Take charge of your inbox with these email apps for iOS

Since I'm a heavy Gmail user, my app of choice is Inbox for Gmail, and it's worked well at keeping my inbox manageable.

• HIGHLIGHTS - Get the most important information without even opening the message. Check-in for flights, see shipping information for purchases, and view photos from friends right up front.
• BUNDLES - Similar messages are bundled together so you can deal with them all at once. And get rid of them with one swipe.
• REMINDERS - More than mail, you can add Reminders so your inbox contains all the things you need to get back to.
• SNOOZE - Snooze emails and Reminders to come back when you are ready to deal with them: next week, when you get home, or whenever you choose.
• SEARCH - Inbox helps you find exactly what you're looking for-- from your upcoming flight to a friend's address-- without having to dig through messages.
• WORKS WITH GMAIL - Inbox is built by the Gmail team, so all your messages from Gmail are here, along with the reliability and spam protection of Gmail. All of your messages are still in Gmail and always will be.

iPGMail is an app that implements the OpenPGP standard (RFC 4880, RFC 6637) and allows the user to create and manage both public and private (RSA, DSA, ECDSA) PGP keys and send and receive PGP encrypted messages.

iPGMail supports PGP key generation (RSA) directly in the app and stores them securely using the iOS keychain for the application. Using your own private PGP keys, you can encrypt and/or digitally sign any messages. Optionally, your public key can be attached to any message you send from the app so that the recipient can then import it into their own keychain, either on the phone or on any computer with PGP support.
