E-mail is now the most popular form of direct response marketing
, per a new
survey of large U.S. corporations conducted by Direct Partners, New York.

E-mail is used primarily by 35% of companies compared to 25% which use
traditional direct mail and 21% who use package, statement stuffers or free
standing inserts

This research ties-in to research conducted last fall from
MarketingSherpa, where participants reported that "house e-mail marketing"
delivered the best return-on-investment in terms of direct response.
