Account e-mail deleted accidentally

an email account was accidentally deleted

is there any option to recover that data (messages)?

and when I go to tab “create new email address” will appear to have as a suggestion to create the same email that was deleted

If you’re lucky, Support can restore it for you. Submit a ticket ASAP.

In the future, either use IMAP so mail gets saved locally on your computer, or also add a forwarder to your Fully Hosted Email to a Gmail account.
