how do i sync email on all devices

Hi VAfromct,

Thanks for posting in Apple Support Communities.

In order to see all your email on your devices be sure to sign in with the correct login for the email account and it will sync to your device. If your have an IMAP account, these changes are saved on the mail server and synced to all devices where you are signed in.

How to set up your email account automatically

If you use an email provider like iCloud, Google, or Yahoo, Mail can automatically set up your email account with just your email address and password. Here's how:

1. Go to Settings > Mail, then tap Accounts.

2.

3. Tap Add Account, then select your email provider.

4. Enter your email address and password.

5. If you see Next, tap Next and wait for Mail to verify your account.

6. If you see Save, tap Save.

If you don't see your email provider, tap Other to add your account manually.

Find these and more details in Add an email account to your iPhone, iPad, or iPod touch - Apple Support.

Regards.
