Postlets.com is a new online classified service with a twist. Postlets allows anyone to build and post a classified ad, and they will not only display it but automatically submit the listing to several classifieds search engines—maximizing your reach across the Internet. For those sites that except HTML, Postlets will generate the code so all you need to do is cut and paste.
So remember, add the sites to your listing plan. The more eyes you can attract the better.
