We are continuing to add to our collection of manuals for creating free open source storefronts for printing and graphic design businesses, with or withing web-to-print and dynamic imaging.
The most recent addition is an article on creating and sending out newsletters from within Magento. It is a relatively simple process anyone familiar with a rich text editor can master within an hour or two. You can always get a professional to do it for you, but having the knowledge and understanding of the process helps anyway. Enjoy.
