Are you missing emails because your iPhone's Email app isn't updating?

The steps below are listed from easy and least invasive to most disruptive.

Open the app's inbox, drag your finger down the screen until you see a spinning wheel, then release it. This prompts the app to (re)connect to the email servers.
