Constant Contact Announces First Quarter 2008 Financial
Results

Quarterly revenue increases 87 percent year over year

Email marketing customer base exceeds 185,000

WALTHAM, MA – May 8, 2008 – Constant Contact^®, Inc (NasdaqGM: CTCT), a leading provider of on-demand email marketing and online surveys for small organizations, today announced its financial results for the first quarter ended March 31, 2008.

Constant Contact reported total revenue of $18.2 million for the quarter ended March 31, 2008, an increase of 87 percent compared with $9.7 million for the comparable period in 2007. Constant Contact ended the first quarter of 2008 with 185,948 email marketing customers, a 78 percent increase over the number of customers at the end of the first quarter of 2007.

“The first quarter of 2008 was another strong quarter for Constant Contact,” said Gail Goodman, CEO of Constant Contact. “We continued to see small businesses and organizations adopting our email marketing and online surveys at a rapid rate, which we believe provides further evidence of the value and effectiveness of our services. In addition, our key operating metrics, including customer retention rates, remained steady year-to-date through April. We believe that 2008 will continue to be a strong year for Constant Contact.”

Constant Contact reported an operating loss of $638,000 for the quarter ended March 31, 2008, an improvement from an operating loss of $2.4 million for the comparable period in 2007. Constant Contact reported an adjusted EBITDA profit of $804,000 in the first quarter of 2008, an improvement from an adjusted EBITDA loss of $1.8 million for the comparable period in 2007. Adjusted EBITDA is a non-GAAP financial measure that is calculated by taking GAAP net income (loss), adding other expense, depreciation and amortization, and stock-based compensation, and then subtracting interest income, net. A reconciliation of the most comparable GAAP financial measure to the non-GAAP measure used above is included at the end of this release.

Constant Contact reported GAAP net income of $338,000 for the first quarter of 2008, as compared with a GAAP net loss of $2.7 million for the comparable period in 2007. First quarter 2008 GAAP net income per diluted common share was $0.01 as compared with a GAAP net loss attributable per common share of $0.79 for the comparable period in 2007. First quarter 2008 non-GAAP net income per diluted common share was $0.03 as compared with a non-GAAP net loss attributable per common share of $0.76 for the same period in 2007. Non-GAAP net income (loss) per share is a non-GAAP financial measure that is calculated by adding back stock-based compensation expense to net income (loss) and dividing this total by the weighted average shares outstanding. A reconciliation of the most comparable GAAP financial measure to the non-GAAP measure used above is included at the end of this release.

“Our financial performance in the first quarter of 2008 exceeded our guidance and was highlighted by higher revenue and adjusted EBITDA. Due to the recurring nature of our revenue, we expect the strong performance in the first quarter to drive revenue levels through the remainder of the year,” said Steven R. Wasserman, vice president and chief financial officer of Constant Contact. “The email marketing and survey markets for small organizations are still in the early stages of their development, and we will continue to invest in expanding our leadership position and growing our customer base.”

Other Business and Operational Highlights

• Added 21,279 net new email marketing customers.

• Constant Contact’s email marketing service was chosen as one of the tools featured in the Intuit^® Marketing Tools Center.

Of the 5,221,000 shares, Constant Contact offered 314,465 shares and selling stockholders offered 4,906,535 shares. The proceeds to Constant Contact from the sale of shares were approximately $4.1 million after deducting the underwriting discount and estimated offering expenses.

Business Outlook

Based on information available as of May 8, 2008, Constant Contact is issuing guidance for the second quarter of 2008 and full year 2008 as follows:

Second Quarter 2008: The Company expects second quarter revenue to be in the range of $20.2 to $20.4 million, adjusted EBITDA to be in the range of $400,000 to $600,000, GAAP net loss to be in the range of $700,000 to $900,000, and GAAP net loss per share to be $0.02. Net loss per share is based on weighted average shares outstanding of 28.0 million shares and includes stock-based compensation expense of $700,000. The Company expects second quarter non-GAAP earnings per share to be $0.00.

Full Year 2008: The Company expects full year 2008 revenue to be in the range of $82.5 to $84.5 million, an increase from our prior guidance of $81.0 to $83.5 million. The Company expects adjusted EBITDA to be in the range of $3.2 to $3.6 million, GAAP net loss to be in the range of $1.8 to $2.2 million, and GAAP net loss per share to be in the range of $0.06 to $0.08, an increase from prior guidance of a loss of $0.09 to $0.11 per share. Net loss per share is based on weighted average shares outstanding (basic) of 28.0 million shares and includes stock-based compensation expense of $3.0 million. The Company expects full year 2008 non-GAAP net income per share to be $0.03 to $0.04 based on weighted average shares outstanding (diluted) of 29.4 million shares.

Non-GAAP Financial Measures

This press release contains three non-GAAP financial measures: adjusted EBITDA, non-GAAP net income (loss) and non-GAAP net income (loss) per share. Constant Contact believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Constant Contact’s financial condition and results of operations. The Company’s management uses these non-GAAP measures to compare the Company’s performance to that of prior periods for trend analyses, for purposes of determining executive incentive compensation, and for budgeting and planning purposes. These measures are used in monthly financial reports prepared for management and in quarterly financial reports presented to the Company’s board of directors. The Company 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 the Company’s financial measures with other software-as-a-service companies, many of which present similar non-GAAP financial measures to investors.

Management of the Company does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded from these non-GAAP financial measures.

In order to compensate for these limitations, management of the Company presents its non-GAAP financial measures in connection with its GAAP results. Constant Contact urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which it includes in press releases announcing earnings information, including this press release, and not to rely on any single financial measure to evaluate the Company’s business.

Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP measures used in this press release are included at the end of this release.
