How do I restore email from icloud

Hello debrafrommurfreesboro and welcome to Apple Support Communities.

It appears you have a concern about restoring email on an iOS device.

If the issue is restoring an account that was deleted, start here:

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

If you are trying to restore individual deleted emails, you'll find instructions here.

Delete and recover emails in Mail on iPhone - Apple Support

Note that if this is an iCloud account, deleted email messages are only available in the Trash folder for 30 days.

Cheers.
