You don't have to send the same one to each Web site, as a matter of fact it may work well if you offer a library of articles for them to choose from. You'll be offering a great service to those Web- masters who don't have the time to keep their content fresh, plus you'll constantly be in front of your prospects. Start a mailing list. Mailing lists, which come to your e-mail instead of you having to go to a separate location on the Internet to find your favorite special interest groups, have become an extremely popular medium on the Internet. There are currently over 30,000 mailing lists on a variety of topics, however don't let the number shock you into believing that all lists are active or that every topic has been taken.
Many mailing lists are for academic purposes and are mainly used by university folk.
I have subscribed to at least 10 lists since February 1996, however only 3 generate messages on a daily basis and only 1 generates a couple of messages every other week or so. Before starting your mailing list, pick a topic that somehow relates to your company. An image consultant might start a list called Dress for Success List which could be geared towards professionals who want to maintain a well-dressed position. If upon searching you discover that there's already a list in existence like the one you wish to start, subscribe to it and see how much traffic is being generated. If there's very little, start a similar one.
