Most of us have used an autoresponder at one point or another in our Internet adventures. Train somebody on a certain topic that you are familiar with. Use an autoresponder to tell somebody that the decision to buy the product was a good one and that they shouldn't worry about wasting money. If you sell advertising on your web site, send a letter to an advertiser asking them what the results of their campaign were good. Ask them to send you testimonials or suggestions to make the advertising more worthwhile.
Most web hosting companies offer free autoresponders as well.
Contact your host and ask them. E-zines are more current than a web site could be, so people rely on a newsletter to keep them informed of the latest headlines. Publishing an e-zine might seem complicated and time consuming at first, but they really aren't that hard. For example, you wouldn't want to publish an e-zine about beetles if your passion is cars. Write about what you know and love.
