Ways you can communicate with your customers for help desk issues
In the days of yore, before the Internet, there were pretty much only two ways for a business to communicate with their customers -- postal service mail or by telephone. With the advent of the Internet and the World Wide Web, this is no longer the case. Besides the obvious postal service mail and telephone contact methods, there are now numerous other ways you can communicate with your customers for help desk issues.
One way would be via email. Just about everyone has an email address, and with all of the free email providers out there (Google GMail, Microsoft Hotmail, Yahoo Mail, etc.) most people are able to have an email address they can use. Most decent help desk Software packages will provide you with a means of communicating with your customers requiring help desk assistance via email. Email is easy to use, easy to access, and provides a way to quickly send messages.
