Studying consumers' past behavior is the best way to predict future behavior. And companies are always looking for new sources for acquisition lists. Now they can do both with ResponderInfo, a new search engine from e-marketing agency ConsumerBase that pulls data directly from the firm's 76 million-record consumer database.

The downloadable information is based on clickstream data collected when consumers respond to e-mail offers sent by the firm's Web sites, including Offerz.com and eShopFirst.com.

Marketers build prospecting lists by selecting from more than 40 clickstream categories and then narrowing them down by attributes such as e-mail or postal address. Companies can also overlay education levels, marital status, and approximate household income.
