I accidentally deleted all my emails. How do I restore them?

No email is backed up to iCloud. No iCloud backup nor iTunes or Finder backup includes emails. Emails live on the servers of the company that provides your email service. So Gmail email lives on Google’s servers, not Apples. Apple iCloud email already lives in iCloud so is not part of any iCloud backup either.

The only thing iCloud backs up is the email account settings, so that when you restore a backup you don’t have to manually set up each email account again. But the emails in that email account sync back from the providers servers, not from Apple’s.

If you emptied the trash on a gmail account, those emails are gone. That’s the whole point of providing a trash folder for deleted emails. The trash provides the place to recover emails if you decide you don’t want to delete them. Once you empty the trash, they are gone and cannot be recovered.

That has nothing to do with Apple nor iCloud nor iCloud backups. Whatever options Google offers to gmail users is up to Google, and a gmail user should be asking Google for support for Google accounts or services, not Apple users on an Apple user forum.

Not only that, but the link you provided indicates someone other than you had access to your gmail account and deleted those emails, not you. If your gmail account is hacked or compromised, that has nothing to do with Apple nor iCloud.

From your link: “Recover your emails that might have been deleted due to someone accessing your account without permission.”

If you had simply been explicit and specific about your situation and issue with your initial post, you may have gotten a much more focused and useful response.

Look in the trash in your email account. You can restore from there.

Restore from an Export:

Did you ever export these from the Mail app? If so, important these. If not, then take this as a learning experience, knowing to always create a backup of your Mail app, that way, you'll have something to restore your Mail form, should anything be deleted.

Go Here: Import or Export Mailboxes in Mail on Mac - Apple Support

FWIW, that link did not work to recover any of my permanently deleted items.
