Try to force close the mail app. You can also reset your device and see if that clears things up
Reset
Hold down the sleep and home keys for about 20 seconds. When you see the silver apple, let go and let it reboot. No data will be lost.
Force close an app
Double tap the home button. When you see the app previews on the screen scroll sideways if needed to get the preview in question on the screen. Flick that preview up and off the screen to close the app. Single tap the home button or home screen preview to exit the mode.
