Troubleshooting iPhone eMails:

A. Go here:

• If you can’t Send eMail on your iPhone, iPad, or iPod touch - Apple Support
• If you can't Receive eMail on your iPhone, iPad, or iPod touch - Apple Support

B. Add the eMail Account Back.

See if it all syncs when you add the eMail Account back. If it is on a Mail server the it should pop up. It may take some time, if you have thousands to download.

C. Use a New App Password:

Do you use an App Password? If so, try a new App Password. Sometimes, changes (i.e. updates) are made to the device, and then mail server syncing becomes an issue (which is what a new App Password it intended to fix). For example, you'd go here for gmail: Sign in with App Passwords - Google Account Help - Google

Troubleshooting eMail New Errors:

Are you using the gmail app? Or are you using the Mail app?

Use a New App Password for Each Device:

Do you use an App Password? If so, try a new App Password. Create a unique on for each device. Remove the current one, and then use the new one instead. Sometimes, changes (i.e. updates) are made to the device, and then mail server syncing becomes an issue (which is what a new App Password it intended to fix).:
