Learn how to set the total number of messages that is going to be display on the iPad.
If the email app on the iPad is showing up to many email messages at one time it could make it difficult for you to read, you could change it so that it display the most recent 25, 50, 75, 100 or 200 messages at the time. Conversely if you like to display alot of the messages at once so you don't have to keep reloading the page then you could increase the list size. Here's how to modify the default setting:
1. Return to the Home screen by pressing the Home button.
2. Tap on Settings.
3. Next tap on Mail, Contacts, Calendars.
4. Select Show.
5. Now you can select to show only your most recent 25, 50, 75, 100 or 200 messages.
More messages will appear as you scroll down the screen.
