Hello,
Thanks for submitting a question about lost emails. First, you will need to check the settings you used to set up the email account. For example, did you use POP or IMAP. Each of these protocols handles mail very differently.
When you say you "lost emails on your hosting site" what exactly do you mean? Do you mean webmail? If so, it's possible the messages were downloaded from your server (which is what happens if you use POP instead of IMAP). If you're unfamiliar with these options, you can always contact our Live Support team, who can troubleshoot email issues with you personally.
Best,
Christopher M.
