Tessa Wegert has written an article on the RSS replacing e-mail newsletter debate.

"What does RSS mean to the content-rich e-newsletter industry? About three months ago, Ken Schafer, president of the Toronto-based Internet consultancy Schafer Group and a founder of The Association for Internet Marketing and Sales (AIMS), simultaneously launched an e-newsletter and added an RSS feed to his company's blog. Though it's difficult to determine exactly how many RSS users subscribe to a feed -- marketers cite this as one of the few limitations of the system -- he estimates that there are about 10 times as many people viewing his feed as the e-newsletter."
