"If you've got to support a business structure with a skinnier stream of revenue, the only way to gain competitive strength is to deal with more people," says Bentley. "The easiest and most important stuff to automate is client communications." That trend accounts for the high number of "template" shops, purveyors of newsletters, e-lists, serial Web content and other "drip marketing" devices that can be customized to the adviser's own needs and clientele.

In Cycle 1, sales-ready leads are forwarded to the appropriate sales person. Prospects who have shown some level of interest but are not sales-ready, are retained for incubation through Cycles 2 and 3. The balance of sales leads with no current value (up to 50 percent or more of the total) are temporarily disqualified and put into automatic drip marketing channels, which support a steady flow of attention and information to prospects.

The phrase drip marketing may sound as though it's based on the practice of water torture, but it actually comes from the phrase drip irrigation. This is an agriculture/gardening technique in which small amounts of water are fed to plants over long periods of time.

Unfortunately for anyone who is the target of a drip marketing campaign, many marketers believe in something called the "Law of 29," which states that on average a "prospect" won't turn into a "client" until they've seen your marketing message at least 29 times (insert groan of dismay here).
