Hello Glen, You can find some new clickbank products on our clickbank mall DownloadsOnline.org in the page 'new downloads'. I do not have information about services that email you about new products.
affiliatealert emails me with product updates into the clickbank marketplace. Great tool for finding affiliate products
We get the information about new products from the Clickbank Marketplace feed. We parse the feed almost everyday and include some new products on the 'New Downloads' page in our clickbank mall.
One can easily know about the newly launched products through the Free Clickbank Mall. The interesting feature of the Free Clickbank Mall is: "It gives you access to the new products, top downloads and the popular downloads" that are seen in the CB Marketplace.
Give http://www.cbengine.com a try for new Clickbank products . . . and also a list of Clickbank products that have been re-listed. Seems many Clickbank products are withdrawn and then released again, for one reason or another. Another location you may like to visit is http://www.cbtrends which offers a similar service covering Clickbank products. CB ENGINE http://www.cbengine.com CB TRENDS http://www.cbtrends.com
