YouSendIt grows subscriber base by 300 percent each year and establishes exclusive industry partnerships

Mountain View, CA – August 1, 2007 –YouSendIt, the trusted global leader in digital content delivery,
today announced that it has significantly grown its business through the acquisition of key customers,
establishing strategic business partnerships and earning key industry awards. YouSendIt continues on its
mission to make digital delivery convenient and secure while saving resources by eliminating the need to
burn files to a CD, package them and send via courier.

As major corporations adopt more advanced and efficient methods of delivering digital files—from huge
video and audio files to complex graphics—they are gravitating to YouSendIt, which continues to expand
its adoption across the globe.

“Our volume of business customers and partners is a testament to YouSendIt becoming a standard
platform for day-to-day business operations,” said YouSendIt CEO Ivan Koon. “We’ve eliminated the
burden of delivery costs and created an entirely new type of workflow, one where the delivery of digital
content is expedited and becomes a natural extension of everyday workplace communication functions.”
Recent additions to YouSendIt’s worldwide roster are the City of Los Angeles, and Parsons the New
School for Design, one of the most prestigious colleges of art and design in the nation. Both have
eliminated the need for using FTP servers or transferring large files to disc and shipping them via
expensive overnight couriers. Instead, they can use the YouSendIt service to securely send files directly
from their computers to multiple recipients, on demand.

These organizations, along with millions of other YouSendIt users, send more than eight million files
every day through the service. YouSendIt transfers over 120 terabytes per month and its subscriber base
is growing more than 300 percent every year.

A number of global technology companies have formed partnerships with YouSendIt, including WinZip,
which provides WinZip users with an easy and secure way to send large files via a co-branded WinZip
Courier service; WindStream, which developed Windstream EZ Send, a fast and easy way for customers
to share large files; 8X8, which joined with YouSendIt to create a new digital courier service for its VoIP
subscribers; and Nuance Communications, which helps YouSendIt distribute a YouSendIt PaperPort ®
Link to provide a seamless way to scan documents and send them directly through the Web.
YouSendIt’s ISP Partnership Program extends to Internet service providers (ISPs) like Windstream and
8X8 the integration of YouSendIt into ISP offerings to offer a co-branded large file delivery service that
generates new revenue and addresses customer pain points. YouSendIt’s Affiliate Program allows ISPs,
ASPs and other service providers to offer YouSendIt’s proven, assured large file delivery service to their
subscribers.

YouSendIt’s impact on global business has been recognized frequently by industry sources, most
recently as a winner of the AlwaysOn 100 Top Private Company Innovators, which was announced at the
2007 Stanford Summit. YouSendIt is also a winner of the WebWare 100 Award, which was selected by
Webware.com users as a favorite Web application.
