On the Internet, it is very possible to make money without selling any
product. One way of doing so is through starting your own eZine, also
known as an electronic newsletter.
In a nutshell, you send out your eZine issues on a periodical basis to
your subscribers. The good part is that you have a flexible choice in
automating the process of sending out your eZine issues for you or
manually sending them on a periodical basis.
