Hide Mail from the Lock Screen in iOS 5
The notifications revamp of iOS 5 makes it easier than ever to see new messages and mail, but if you receive sensitive or private emails on your iPhone or iPad, you may not want them showing up on the lock screen.
Those little email previews are easy to hide, here’s how:
- Open “Settings” and then tap on “Notifications”
- Tap on “Mail” and scroll to the bottom to “View in Lock Screen” and slide the adjuster to OFF
This will stop the email sender and subject info from being shown on the locked screen anytime a new email arrives. If you want to disable the notifications from appearing at the top of the screen as well, you’ll need to select the “None” option in the three side-by-side options at the top of that same settings screen.
For those who had this disabled to begin with, you can obviously reverse this process to turn the lockscreen email previews on, but be aware that anyone who picks up the iOS device can then see the basic sender and subjects of the newest email messages, even without entering a pass code.

Awesome tip. Works on my iPad too, but you already pointed that out. Thanks!
Almost a better tip in that screen cap is disabling the mail badge icons, which you can also do with other apps too. Great if you have enterprise email hooked up and are annoyed with all the ding-a-lingy red buttons!
I wish you could chose which email accounts showed up on the notifications, as I don’t want my junk mail account buzzing my phone all the time.
Good tip, but another option is to leave “View in Lock Screen” on, but turn off “Show Preview”. That way you’ll only see the sender of the message =)
