Twitter's Lead Generation ad product shares email addresses with advertisers. Wait, what?
Adam Rifkin stashed this in Twitter!
Twitter started testing a new "lead-generation" ad product today, and it looks a lot like a Groupon-style daily deal product.
The ad unit comes in one of Twitter's Cards, the expandable display unit that allows users to show a photo.
Advertisers can offer Twitter users discounts or deals in the unit, and anyone who wants to claim it can do so with the click of a button. The unit automatically forwards the user's Twitter ID and email to the advertiser, who then fulfills the deal.
"Marketers regularly talk to us about their goals, and for many it boils down to one major theme: generating leads, and ultimately driving purchases," said Mitali Pattnaik Twitter's product manager/revenue in a blog post.
