BlueHornet Networks Adds Two Features to its SureSend E-Mail Deliverability Enhancement Platform

Enables online marketers to optimize HTML e-mail appearance and usability

MINNEAPOLIS, May 4, 2007 — BlueHornet Networks, Inc., a leading provider of e-mail marketing solutions and subsidiary of Digital River, Inc. (NASDAQ: DRIV), today introduced two new components of its SureSend™ e-mail deliverability enhancement platform – the HTML Design Consultant and Message Rendering Report. These e-mail design tests help online marketers and graphic designers identify and correct HTML coding issues that could affect how e-mail images display and function in widely used e-mail programs.

The SureSend HTML Design Consultant checks HTML e-mail templates for potential coding problems and best practice compliance. Test results then provide information on “how-to-fix” identified issues.

The SureSend Message Rendering Report shows online marketers how their HTML appears in 15 leading desktop- and Web-based e-mail programs, such as Microsoft Office Outlook® 2007, Microsoft Hotmail® and Google’s Gmail™ webmail services. It shows how an e-mail displays when images are turned off as well as its placement in the viewing area of the screen. Marketers can use this information to ensure that key components of their e-mail message appear in optimal viewing space for recipients.

“HTML rendering standards change frequently and vary depending on the e-mail program that recipients use, which can pose challenges for many online marketers,” said Chuck Davis, vice president of Digital River’s BlueHornet business unit. “By using our two new SureSend features as an integrated part of our BlueHornet eMarketing Suite, users now can easily optimize their e-mail HTML, which can help reduce costs, save time and ultimately increase the revenue generated from e-mail campaigns. These new tools also help reduce the time needed for accurate message creation and testing by more than half.”

BlueHornet’s SureSend platform is designed to help online marketers improve e-mail inbox deliverability rates and achieve improved results from e-mail campaigns. SureSend combines integrated tools with expert consultation to keep marketers informed about the rapidly changing criteria ISPs and other industry providers use to determine which messages get delivered, filtered or blocked.
