The United States Postal Service is looking to get in on the big-data-for-profit game played by tech giants like Facebook and Google, and begin mining and selling private data gathered from personal mail sent from and received by Americans everywhere.

USPS chief marketing and sales officer Nagisa Manabe recently told the forward-looking PostalVision 2020 conference that the post office is “actively looking for ways to build new business lines around what not long ago might have been considered science fiction,” eCommerce Bytes reports.

While some of those ideas included new delivery services from partnerships like grocery chains, others seek to increase revenues from advertising by mining, storing and analyzing customer data. By mapping those datasets and determining consumer behavior, advertisers and retailers could target more effectively through traditional mail, much the same way Facebook and Google target ads based on search, profile, email and other data.

Manabe described an example scenario in which a woman test drives two different types of cars and two different dealerships while trying to decide which to buy.
