From the Apple support site, a good place to check for help on your iPad
Before you can use your email account on iPad - you need to add your account to Mail.
Tap Mail
Select your account type. Tap Other if your account is not listed.
Enter your account information and tap Save. Mail configures most email accounts automatically. Otherwise, you will be prompted for any additional settings.
Once your account information is saved - you can start sending and receiving email.
You can configure additional accounts by tapping Settings > Mail, Contacts, Calendars > Add Account
And here is my quick version:
Settings
Mail (5th one down)
Add account
Other
Add account
Fill in info
And below is the Apple support site for your iPad...
