email

Hello par1892,

Welcome to Apple Support Communities. First, make sure that the email account is on your iPhone. You can find those accounts from Settings > Mail > Accounts as mentioned in Add an email account to your iPhone, iPad, or iPod touch.

If needed, add it using the following guidance from the same article.

"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. Tap Add Account, then select your email provider.
3. Enter your email address and password.
4. If you see Next, tap Next and wait for Mail to verify your account.
5. If you see Save, tap Save."

If the account is already there, tap the account name and make sure that Mail is enabled.

Take care.
