The zumbox website indicates that zumbox will not only send bills and statements, but also direct marketing mail, which the public commonly refers to as junk mail. Direct marketers like to use paper “junk mail” for it’s high visual impact and the resulting response rates. One reason for the high visual impact, is the low daily volume of received paper “junk mail”. Printing and postage costs are preventing, that the consumer is hammered with truly annoying amounts of paper “junk mail”.

So how will zumbox regulate the digital “junk mail” volumes? Trying to preserve the success of paper “junk mail” is an attractive choice, but revenue driven business needs may contradict this. It will be interesting to watch how zumbox will manage conflicting needs throughout the various stages of their business life cycle.

Overall, we feel that excessive amounts of (unsolicited) direct mail would make zumbox less attractive for consumers. Zumbox gives users at least the option to block specific senders. But that may turn into a whack-a-mole situation, if excessive “junk mail” is sent by quick growing numbers of new mailers.

Zumbox has created a handy suite of comfortable tools for potential mailers. If the price, for delivering “junk mail” through zumbox, is too low, then the “junk mail” volumes on zumbox could quickly reach levels, which are beyond consumer acceptance.

We conclude that zumbox will need mechanisms, which keep digital “junk mail” volumes well within consumer accepted levels, as is the case with paper based “junk mail” volumes.

We are looking forward to watch zumbox and like to invite your comments.
