The vendor says its service will allow for comprehensive analysis by taking into account click-stream data, customer interaction data, surveys, and demographics. Following a real-time predictive analysis model, the software indicates to Web sites and call-center representatives which offers a customer is likely to accept. RightPoint.net will be available in August, starting at $7,500.

No one has measured the size of the still-young marketing automation space, but analysts say it's growing fast. Such software lets companies "track customer interactions over the Web," says Steve Bonadio, a research analyst with the Hurwitz Group, "then mine that data to up-sell and cross-sell."

No wonder, then, that Annuncio Software Inc. last week signed three marquee customers. E-Stamp, Lucent Technologies, and Xerox are implementing the Annuncio Live marketing automation application to automate their Internet marketing campaigns and acquire and retain customers over the Web.

E-Stamp, an Internet postage company, is using Annuncio to measure the effectiveness of its online advertising campaigns and analyze customer response. "Annuncio helps us manage the cost of acquiring and retaining customers," says Ellen Perelman, director of business development at E-Stamp.
