I understood that you are looking to create a business email for your business, and you are facing some issues to create it successfully.
I have extensive knowledge in Cpanel and creating business emails, and I created all the business emails for the company I work for and managing all the email.
I also had excellent experience in creating and managing emails with google suite.
So I strongly believe that I can solve your issue by creating your business email for you.
Please help me with the error you are getting.
