Since the demise of Faxes, the world has moved to faster more secure forms of electronic communication. The most reliable and overused form is Email but one of essential parts of your business. This is set up with an ISP (Internet service provider) or a domain host directed to an exchange platform. For business, we recommend that email is representative of your business.
I.E name@your company.co.nz what we see too often is company@ISP.co.nz
This is misleading and difficult to manage as the business grows.
