Can I restore a email account I deleted by accident?

Hello, Kriswet1.

If you want to bring an email account back to the Mail app on your iPhone, you can definitely add it back. Just follow these steps: Add an email account to your iPhone, iPad, or iPod touch - Apple Support.

"How to set up your email account automatically

1. Go to Settings > Mail, then tap Accounts.
2. Tap Add Account, tap Other, then tap Add Mail Account.
3. Enter your name, email address, password, and a description for your account.
4. Tap Next. Mail will try to find the email settings and finish your account setup. If Mail finds your email settings, tap Done to complete your account setup.

Enter account settings manually 

If Mail can't find your email settings, then you need to enter them manually. Tap Next, then follow these steps:

1. Choose IMAP or POP for your new account. If you aren’t sure which one to choose, contact your email provider.
2. Enter the information for Incoming Mail Server and Outgoing Mail Server. Then tap Next. If you don't have this information, try to look it up.
3. If your email settings are correct, tap Save to finish. If the email settings are incorrect, you'll be asked to edit them. If you still can't set up your email account or save your email settings, contact your email provider."
