BlueHornet Networks’ Management to Speak at Jupitermedia’s INBOX 2007 Event

MINNEAPOLIS, May 24, 2007 — BlueHornet Networks, Inc., a leading provider of e-mail marketing solutions and subsidiary of Digital River, Inc. (NASDAQ: DRIV), today announced that the company has accepted an invitation to present at INBOX: The Messaging Industry Event. The event will be held May 31-June 1, 2007, at the San Jose Marriott in San Jose, CA. Registration is open to the public.

BlueHornet’s management will participate in a panel discussion entitled “Sanitation, Segmentation, Reputation and Other Delivery Solutions.” The panel will address issues relating to e-mail authentication and double opt-in best practices.

“I’m pleased that BlueHornet has been selected to share its knowledge about how online merchants can authenticate their e-mails and best protect their reputations as e-mail senders,” said Chuck Davis, vice president of Digital River’s BlueHornet business unit. “These two particular areas of e-mail delivery optimization can present special challenges, since they must be approached from two historically disparate divisions within a sender’s organization - the IT department and the marketing team. This INBOX panel discussion will unite both sides to find effective business solutions.”

INBOX: The Messaging Industry Event brings together business, IT, vendors and industry pioneers to address technology trends, business dynamics and new models of electronic messaging and communication. To learn more, visit http://www.inboxevent.com.
