cannot get my e-mail to work on my iPhone 6 plus

Good Afternoon dterryjr,

Thanks for the question. I'm assuming this is your first iPhone and you are not trying to restore from another iPhone? If so, I'll include some information below to help you set up your email account(s) in the Mail app on your iPhone:

Add an email account on your iPhone, iPad, or iPod touch - Apple Support

Add an email account on your iOS device

1. Tap Settings.
   
2. Scroll down and tap Mail, Contacts, Calendars.
   
3. Tap Add Account.
   
4. Select your email provider. If you don't see your email provider listed, tap Other > Add Mail Account.
   
5. Provide the required information to finish adding your account.

If you use a common email provider, your device will load your email settings automatically. If your device doesn't load these settings and you don't know them, contact your email provider and ask for this information:

Set up other mail, contacts, and calendar accounts

iPhone works with Microsoft Exchange, and many of the most popular Internet-based mail, contacts, and calendar services.

Set up an account. Go to Settings > Mail, Contacts, Calendars > Add Account.

You can add contacts using an LDAP or CardDAV account, if your company or organization supports it. See Add contacts.

You can add calendars using a CalDAV calendar account, and you can subscribe to iCalendar (.ics) calendars or import them from Mail. See Use multiple calendars.

For information about setting up a Microsoft Exchange account in a corporate environment, see Mail, Contacts, and Calendar.

The iPhone User Guide above and the Tips and Tricks app are both on your iPhone. These two resources should help with your initial questions.
If you need clarification or a question isn't answered, that's why we are here!
