EX-99.1

WALTHAM, Mass. – April 30, 2009 – Unica Corporation (Nasdaq: UNCA), a leading global provider of enterprise marketing management (EMM) solutions, today announced financial results for its second quarter fiscal 2009 ended March 31, 2009.

For the second quarter fiscal 2009, the company reported total revenue of $23.3 million, consistent with the company’s preliminary results. This represents a decrease of 24% compared with the second quarter of fiscal 2008. Subscription revenue was $4.4 million, an increase of 45%, perpetual license revenue was $4.2 million, a decrease of 64%, maintenance revenue on perpetual licenses was $10.8 million, an increase of 1%, and services revenue was $3.8 million, a decrease of 29%, each compared to the second quarter fiscal 2008.

“While our business related to perpetual software licenses continues to face strong economic- related headwinds, our subscription-based offerings are experiencing solid demand levels and growth. During the second quarter, we also closed several sizeable transactions on a subscription basis even though our solutions are being deployed on-premise,” stated Yuchun Lee, chief executive officer of Unica Corporation. “We believe the EMM market will experience healthy demand for both subscription and perpetual license solutions from a long-term perspective. This supports our strategy to provide customers with flexibility in their purchase and deployment options, which enables Unica to maximize its addressable market opportunity and adapt to customer’s changing preferences over time.”

Lee added, “We continue to believe that EMM represents a large, under-penetrated market opportunity. In addition, we are highly confident in Unica’s ability to weather this economic cycle based on our market and technology leadership position, large customer base and strong balance sheet. ”

For the quarter ended March 31, 2009, Unica reported loss from operations, in accordance with generally accepted accounting principles (GAAP), of $17.3 million, compared to loss from operations of $777,000 for the quarter ended March 31, 2008. GAAP loss from operations for the quarter ended March 31, 2009 includes $1.3 million of non-cash share-based compensation expense, $678,000 of amortization of acquired intangible assets and a $15.3 million goodwill impairment charge. GAAP net loss for the quarter ended March 31, 2009 was $16.1 million, compared to GAAP net loss of $277,000 for the quarter ended March 31, 2008. GAAP net loss per share for the quarter ended March 31, 2009 was $0.77, compared to GAAP net loss per share of $0.01 in the corresponding quarter of the prior year.

During the closing process for the quarter ended March 31, 2009, the company performed an interim impairment assessment of its goodwill and other intangible assets due primarily to the decline in the company’s market capitalization and operating results caused by the difficult economic environment. As a result of this assessment, the company recorded a $15.3 million expense relating to the impairment of goodwill. A related adjustment was also made to the company’s balance sheet.

For the quarter ended March 31, 2009, non-GAAP income from operations, which excludes the above mentioned non-cash share-based compensation expense, amortization of acquired intangible assets, and the goodwill impairment charge, was approximately break-even, compared to non-GAAP income from operations of $1.5 million for the quarter ended March 31, 2008. Non-GAAP net loss was $338,000 for the quarter ended March 31, 2009. This compares to non-GAAP net income of $1.2 million for the quarter ended March 31, 2008. Non-GAAP net loss per diluted share was $0.01 for the quarter ended March 31, 2009, compared to net income per diluted share of $0.05 for the corresponding quarter of the prior year.

A reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures.”

As of March 31, 2009, Unica had cash, cash equivalents and investments of $47.7 million, an increase compared to $46.5 million at December 31, 2008, due primarily to $2.5 million of cash provided by operations.

At March 31, 2009, deferred revenue was $37.3 million, a decrease compared to $37.9 million at December 31, 2008.

Kevin Shone, chief financial officer of Unica, said, “Unica’s commitment to improving its operational efficiency is reflected by the third consecutive quarter in which non-GAAP operating expenses have been reduced, leading to an 18% reduction compared to the prior-year quarter. In light of the continued challenging macro environment, we will continue to focus on cost controls. We will continue to invest in our growth initiatives with the goal of delivering positive non-GAAP operating profitability for the full year fiscal 2009.”

The preceding forward-looking information with respect to non-GAAP operating income for the full year fiscal 2009 excludes share-based compensation expense, amortization of acquired intangible assets related to previous acquisitions and the impairment of goodwill, but includes restructuring charges incurred during the first quarter.

A replay of this conference call will be available from 8:00 p.m. ET on Thursday, April 30, 2009 through 11:59 p.m. ET on Thursday, May 14, 2009 at 888-203-1112 (domestic) or 719-457-0820 (international).

Unica has provided in this press release selected financial information that has not been prepared in accordance with GAAP. This information includes historical non-GAAP operating income, net income, and earnings per share.

Unica uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating Unica’s ongoing operational performance. Unica believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends, and in comparing its financial results with other companies in Unica’s industry, many of which present similar non-GAAP financial measures to investors. Specifically, on both an historic and a forward-looking basis, these non-GAAP measures exclude:

•

Expense associated with the amortization of intangible assets related to acquisitions and the impairment of goodwill, as exclusion of these expenses allows comparisons of operating results that are consistent over time for both the company’s newly acquired and long-held businesses and with both acquisitive and non-acquisitive peer companies.

•

Expense associated with share-based compensation related to options to purchase common stock, the employee stock purchase plan and restricted stock units because, while share-based compensation is a significant ongoing expense affecting the company’s results of operations, the company’s management excludes share-based compensation from the company’s

forecasting and planning process used to allocate resources. In addition, because of varying available valuation methodologies, subjective assumptions and the variety of award types, the company believes that excluding share-based compensation may enable useful comparisons of the company’s operating results to its competitors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure as detailed above. As previously mentioned, a reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release.
