When it comes to one-to-one communication email is highly effective and it would be hard to image any new medium replacing it. However with email newsletters and email marketing campaigns experiencing higher and higher block rates due to spam filters and the subscribers themselves being inundated, RSS does seem like a very viable alternative. We believe RSS offers unique content delivery opportunities especially for “push” marketing such as Newsletters and email campaigns. The fact that RSS is a less obtrusive “pull” channel and is 100% opt-in (should avoid most issues related to the CAN-SPAM Act) creates the opportunity to overcome some of the new email obstacles.
