delete emails

Hi giulio198,

Thanks for coming to Apple Support Communities for help today.

There's a page in the Mail User Guide with suggestions that may help: If emails appear to be missing in Mail on Mac

"If messages seem to be missing from mailboxes, try these suggestions.

• If you use more than one email account in Mail, make sure you’re looking at messages for the correct account.
• If you sorted messages, they may be in the list but not in the order you expect.
• If you use rules, they may have moved messages to other mailboxes. Try searching for the messages.
• Check the account’s Recovered Messages mailbox, if available in the Mail sidebar.
• Quit Mail, then reopen it.
• If the problem persists, you may need to rebuild a mailbox."

You may also want to check to see if the emails are available on your provider's webmail portal through a browser.

Have a fantastic day!
