Request to Permanently Delete Email User (info@mehbobgulf.com ) from Old Organization

Please permanently delete the user email
info@mehbobgulf.com

It is still associated with my old Zoho organization.
I cannot delete it because it shows ‘You cannot delete email. Zoho host’.
I need to use this email in a new Zoho account.”
