Your Customer's Needs Mailing lists are kinda sorta like forums, except that you receive postings via email instead of reading them via a web site. There are thousands of mailing lists, all tailored to specific interests, hobbies, business needs and more.
Mailing lists promote a sense of community.
This is very valuable when you are learning about your customer base or marketing your product. Producing your own mailing list is rather easy. Some of the more popular, free software include Lyris and Majordomo . If you'd prefer not to set up actual software, you can take advantage of the many list-creation services like Egroups or Onelist . You can also search for mailing lists at these sites, too.
