Constant Contact Announces Second Quarter 2008 Financial
Results

Quarterly revenue increases 82 percent year-over-year

Email marketing customer base exceeds 207,100

WALTHAM, MA — August 12, 2008 — Constant Contact^®, Inc (NasdaqGM: CTCT), a leading provider of email marketing and online surveys for small organizations, today announced its financial results for the second quarter ended June 30, 2008.

Constant Contact reported total revenue of $20.8 million for the quarter ended June 30, 2008, an increase of 82 percent compared to revenue of $11.4 million for the comparable period in 2007. Constant Contact ended the second quarter of 2008 with over 207,100 email marketing customers, an increase of over 67 percent compared to the end of the second quarter of 2007.

“Constant Contact continues to extend its market leadership position, as evidenced by the over 21,200 net new email marketing customers who added our service during the second quarter. Our passionate focus in helping our customers succeed is a key differentiator for the Company, and during the quarter we were pleased to win an industry award for outstanding customer support,” said Gail Goodman, CEO of Constant Contact. “The continued strong growth in our customer base, particularly in the current challanging economic environment, demonstrates the value that we provide by helping our customers easily and professionally communicate with their members and customers, at an incredibly affordable price. I am very pleased with our accomplishments year-to-date and continue to be excited about our prospects for the remainder of 2008 and beyond.”

Constant Contact reported an operating loss of $1.1 million for the quarter ended June 30, 2008, an improvement from an operating loss of $2.5 million for the comparable period in 2007. Constant Contact reported adjusted EBITDA of $894,000 in the second quarter of 2008, an improvement from an adjusted EBITDA loss of $1.7 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 net interest income. Adjusted EBITDA margin is equal to adjusted EBITDA divided by revenue. 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 a GAAP net loss of $389,000 for the second quarter of 2008, an improvement compared to a GAAP net loss of $2.8 million for the comparable period in 2007. Second quarter 2008 GAAP net loss per share was $0.01 as compared to a GAAP net loss attributable per common share of $0.81 for the comparable period in 2007. Second quarter 2008 non-GAAP net income per diluted common share was $0.01 as compared to a non-GAAP net loss attributable per common share of $0.78 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).

“The second quarter of 2008 was another successful quarter for Constant Contact as we outperformed relative to our expectations and each of our key customer metrics remained within historical ranges,” said Steven R. Wasserman, vice president and chief financial officer of Constant Contact. “Our customer retention rates remained steady during the second quarter and we continue to anticipate a typical seasonal pickup in customer additions as we move into the fourth quarter of the year.

GAAP net loss per share is based

Page 3

on weighted average shares outstanding (basic) of 28.1 million shares and includes stock-based compensation expense of $700,000. The Company expects third quarter non-GAAP net income per share to be $0.00 to $0.01 based on weighted average shares outstanding (diluted) of 29.4 million.

Full Year 2008: The Company expects full year 2008 revenue to be in the range of $85 million to $86 million, up from previous guidance of $82.5 to $84.5 million. The Company expects adjusted EBITDA to be in the range of $3.3 million to $3.6 million, consistent with the Company’s target of delivering an adjusted EBITDA margin of four percent for the year. The Company expects GAAP net loss to be in the range of $1.8 million to $2.1 million, and GAAP net loss per share to be in the range of $0.06 to $0.08. GAAP net loss per share is based on weighted average shares outstanding (basic) of 28.0 million shares and includes stock-based compensation expense of $2.8 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 four non-GAAP financial measures: adjusted EBITDA (loss), adjusted EBITDA margin, 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.
