Experian CheetahMail and Omniture Partnership Helps U.S. Auto Parts Network,
Inc. Increase E-mail Revenue and Boost Campaign Performance
Leading online automotive parts retailer leverages real-time online analytics
data to create customer-centric e-mail marketing campaigns

SCHAUMBURG, Ill., OREM, Utah, and CARSON, Calif., Aug. 17 /PRNewswire/ --
Experian(R) CheetahMail(R), a global leading provider of e-mail marketing and
customer intelligence technologies, and Omniture(R), (Nasdaq: OMTR), a leading
provider of online business optimization software, today announced that U.S.
Auto Parts Network, Inc. (USAP) has boosted revenue per e-mail and transaction
rates 50 times higher than its standard, promotional e-mail campaigns. USAP,
an established and innovative retailer of automotive equipment and supplies
online, accomplished this through the integrated use of Experian CheetahMail's
e-mail marketing technology and Omniture's SiteCatalyst(TM) through Omniture
Genesis(TM).

Using the Internet as its main channel for selling superior-quality automotive
parts and accessories nationwide, USAP aims to engage every visitor who
browses its e-commerce site, http://www.autopartswarehouse.com. During this
initiative, Experian CheetahMail and Omniture have leveraged their established
partnership and combined their best-in-breed technologies to implement a
high-performing remarketing program for USAP.

USAP's remarketing program employs Omniture SiteCatalyst for online analytics
and Experian CheetahMail's e-mail marketing technology to send relevant,
automatically triggered messages that remind customers about products that
remain in their online shopping carts. This combination of behavioral data and
targeted messaging has brought significant lifts to the transaction rates,
click-throughs and revenue per e-mail of USAP's remarketing e-mails.
Additionally, USAP has experienced a significant decrease in remarketing
e-mail bounce rates and an increase in reach directly attributable to this
program.

"U.S. Auto Parts is committed to being the consumer advocate for vehicle
owners looking to service their automobiles in a cost-effective manner; and we
understand that every customer touch-point is critical to increasing lifetime
value," said Houman Akhavan, vice president of marketing for USAP. "By working
with Experian CheetahMail and Omniture to seamlessly measure and combine our
online behavioral data with our e-mail data, we are able to send meaningful
messages that our customers respond to. This type of communication strategy
not only increases return on investment and conversions directly attributable
to our remarketing program, it also allows us to continually refine our
strategy and make the channel more meaningful with every customer experience."

In addition to measuring USAP's abandoned cart program, Omniture SiteCatalyst
integrates Experian CheetahMail's e-mail data with information from USAP's
other online marketing initiatives. This provides USAP with a single view of
the performance of its e-mail marketing campaigns alongside all other online
marketing initiatives, such as paid search and affiliate marketing. The
integration with Omniture SiteCatalyst and CheetahMail happens through
Omniture Genesis, a marketing platform and a component of the Omniture Online
Marketing Suite that integrates complementary third-party applications with
Omniture products.

"Our partnership with Omniture enables clients like USAP to leverage rich
behavioral Web site data to send more relevant and timely e-mail
communications to their customers," said Matthew Seeley, platforms division
president for Experian Marketing Services. "The technology is seamlessly
integrated, reliable and efficient, allowing our clients to focus more on
strategy, revenue growth and competitive differentiation."

"The Omniture Genesis integration with Experian CheetahMail demonstrates our
ongoing commitment to deliver meaningful integrations with our accredited
Genesis partners that address the needs of mutual customers," said John
Mellor, executive vice president of business development and corporate
strategy at Omniture. "This integration allows retailers to gain important
insight into the products, services and experiences their customers want by
viewing data from e-mail marketing alongside all other online marketing
initiatives. This helps retailers better optimize every customer engagement
with highly relevant messages."
