RE:     RETENTION PROGRAM

Dear Bill:

        Our board of directors has determined that it would be in the best
interests of Digital Impact, Inc. (the "COMPANY") and its stockholders to offer
you a cash-based retention package on the terms set forth below.

        Subject to your continued status as an employee, director or consultant
of the Company ("SERVICE"), the Company will pay you $100,000, less any
applicable withholding and employment taxes, on each of January 1, 2003, 2004
and 2005 (each, a "RETENTION DATE").

        If at any time during the term of this agreement (i) the Company
terminates your Service without Cause (as defined on Schedule A), (ii) you
resign your Service for Good Reason (as defined on Schedule A) or (iii) you die
or become disabled, the Company shall pay you the retention payment due on the
next following Retention Date and shall thereafter have no further obligation to
you hereunder. If you resign your Service other than for Good Reason or the
Company terminates your Service for Cause, the Company shall have no further
obligation to you hereunder.

        This agreement may only be amended, modified or terminated by an
agreement in writing signed by you and the Company. This agreement shall be
binding upon the Company and its successors and assigns. This agreement shall be
governed by the internal laws of the State of California without regard to
principles of conflict of laws.

Very truly yours,

DIGITAL IMPACT, INC.

        "CAUSE" shall mean the willful engaging by you in criminal or fraudulent
acts or gross misconduct that is demonstrably and materially injurious to the
Company, monetarily or otherwise. No act or failure to act on your part shall be
deemed "willful" unless done or omitted to be done by you not in good faith and
without reasonable belief that your action or omission was in the best interest
of the Company. Notwithstanding the foregoing, you shall not be deemed to have
been terminated for Cause unless and until there shall have been delivered to
you a copy of a resolution duly adopted by the affirmative vote of not less than
three quarters (3/4) of the non-employee members of the Board at a meeting of
the Board called and held for such purpose (after reasonable notice to you and
an opportunity for you, together with your counsel, to be heard before the
Board), finding that in the good faith opinion of the Board, you were guilty of
conduct set forth above in the first sentence of this definition and specifying
the particulars thereof in detail.

        "GOOD REASON" shall mean, without your express written consent, (i) a
material and detrimental alteration of your responsibilities from those in
effect on the date hereof or (ii) the relocation of the office of the Company
where you are employed on the date hereof to a location which is more than 35
miles away from such office or the Company's requiring you to be based more than
35 miles away from such office (except for required travel on the Company's
business to an extent substantially consistent with your customary business
travel obligations in the ordinary course of business prior to the date hereof).<PAGE>

365-day year and the actual number of days elapsed. Interest will be compounded
annually on February 1 of each year during the term of this Promissory Note.

        3. Prepayment. This Promissory Note may be prepaid in whole or in part
at any time, without premium or penalty. If at any time prior to the repayment
of all unpaid principal and interest hereunder, Borrower sells any shares of
Lender stock, Borrower shall apply fifty percent (50%) of the after-tax proceeds
of any such sale to the repayment of unpaid principal and interest hereunder. In
addition, if Borrower becomes entitled to any cash bonuses or severance payments
from Lender at any time prior to the repayment of all unpaid principal and
interest hereunder, Lender, in its discretion, may apply any portion or all of
such bonus or other payment to the repayment of unpaid principal and interest
hereunder.

        4. Termination of Employment. If Lender terminates Borrower's service
for Cause (as defined on Schedule A) or Borrower resigns other than for Good
Reason (as defined on Schedule A), all unpaid principal and interest hereunder
shall become immediately due and payable.

        5. Waiver. Borrower hereby waives presentment, demand, notice of
dishonor, protest, notice of protest and all other demands, protests and notices
in connection with the execution, delivery, performance, collection and
enforcement of this Promissory Note. Borrower shall pay all costs of collection
when incurred, including reasonable attorneys' fees, costs and expenses.

        6. Miscellaneous. This Promissory Note may only be amended, modified or
terminated by an agreement in writing signed by the party to be charged. This
Promissory Note shall be binding upon the heirs, executors, administrators,
successors and assigns of Borrower and inure to the benefit of Lender and its
permitted successors, endorsees and assigns. This Promissory Note shall not be
transferred without the express written consent of Lender, provided that if
Lender consents to any such transfer or if notwithstanding the foregoing such a
transfer occurs, then the provisions of this Promissory Note shall be binding
upon any successor to Borrower and shall inure to the benefit of and be extended
to any holder thereof. This Promissory Note is being delivered in, is intended
to be

performed in, shall be construed and interpreted in accordance with, and be
governed by the internal laws of, the State of California, without regard to
principles of conflict of laws.

        BORROWER UNDERSTANDS THAT THIS IS A FULL RECOURSE PROMISSORY NOTE AND
THAT LENDER MAY, AT ITS OPTION, PROCEED AGAINST ANY OF THE ASSETS OF BORROWER IN
THE EVENT OF A DEFAULT.
