Compared to direct 'print-based' marketing, there are no print, fulfilment or postage costs, yet you have far greater flexibility in terms of content and targeting and a much easier and more immediate response mechanism.
Email supersedes direct marketing.
By 2004 the average household will receive nine pieces of marketing email every day. It provides an easy way to interact with groups of your customers with news and press releases and it can also create subscription lists or discussion forums. Once a list is set up, virtually all operations can be performed remotely saving you time and money. Anybody with an email account can subscribe to a mailing list. Majordomo creates a special e-mail address with each mailing list for people to send subscription requests to.
