                         INFOUSA ACQUIRES YESMAIL, INC.


(Omaha, Neb.) March 3. 2003 --infoUSA Inc. (Nasdaq: IUSA) a leading provider of
proprietary business and consumer databases and sales and marketing solutions,
and Yesmail, Inc., a leading provider of email acquisition and retention
services and a majority-owned operating company of CMGI, Inc. (Nasdaq: CMGI),
today announced that infoUSA acquired Yesmail for cash pursuant to the terms of
a definitive merger agreement on February 28, 2003.

The Yesmail business is comprised of two parts; an email deployment and
automation technology business, located in San Francisco, and an email brokerage
and management business, based in Chicago. Ed Henrich, who has been a senior
executive with Yesmail), will serve as President of the San Francisco
operations. Ed Mallin, President of Walter Karl, infoUSA's List Management and
Brokerage Division, will run the Chicago division of Yesmail.

Vin Gupta, Chairman and CEO of infoUSA, stated, "We are excited about acquiring
Yesmail's automation technology, email brokerage service business and blue chip
client base, all of which perfectly complement and broaden our existing email
management and automation solutions. We intend to quickly integrate Yesmail with
our growing email marketing operations."

George A . McMillan, president and chief executive officer, CMGI, Inc., said, "
CMGI is focusing on fewer businesses where it can sustain market leadership. It
became apparent that Yesmail, as our sole business in email brokerage and
management, would benefit from an alliance with a larger direct marketing
company."

As a result of this transaction, the financial results of Yesmail, including its
net revenues, pro forma operating losses, and cash and cash equivalents
balances, will no longer be included in CMGI's consolidated financial
statements.
