If you are using the Email/Mail application (not Gmail), you can try to clear the data for the application. You will have to re-add all your email accounts again and set them up. That's one way I know to clear out odd email counts.

Hi emailoverdose. I can see where you got your username. It certainly can seem like a lot of work finding a pesky little email. So let's find an easy solution for you. What kind of email (Gmail, Yahoo, AOL, etc) is it that's hiding on you? What application are you using on your phone to check that email account? Have you checked to make sure there's no unread email in a subfolder or possibly even in drafts?
