How to get rid of mail number on e-mail icon?

Normally the number that appears in the red circle on your Mail app refers to the number of unread emails you have. Sometimes though the Mail app gets confused and doesn't work properly. If you are seeing that big number and are sure that you have no unread emails, then I suggest quitting the Mail app like I describe and then reset your device. Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app. Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Open your mail app and open the email.

What if you delete your mail account and re-add it?
