As a G suite administrator, you can give a user in your organization an alternate address for receiving email. Do this by adding an email alias to the user's account in your Google Admin console.
Why use an alias? If bill@solarmora.com wants a sales address for posting to the company website, give him the email alias sales@solarmora.com. Mail sent to either address then appears in Bill's Gmail inbox.
