While I am coming more and more to the conclusion that, for the time being, RSS and email must be cohabitant marketing communications tools, there is still a debate brewing. Alex Barnett, Online Customer Experience Manager for Microsoft UK (how's that for a title!), discusses it in two posts: RSS Future - Distributed marketing and the solution to spam? and Email v RSS, let us move on. The later post contains a rather extensive listing of email and RSS positives and negatives.
For me, the debate was settled after having read an article by marketing executive Tom Barnes, CEO of MediaThink. In a first of two-part series entitled RSS: Marketing's Next Big Thing, Tom outlines advantages to both strategies and shows how they can work in simpatico. *The article is premium content, so I'm being careful not to raise the ire of Marketing Profs attorneys by giving away too much information. :-) But, you ought to become a subscriber to Marketing Profs anyway.*
