Exhibit 99.1

Think Partnership Preferred Shareholders are now Committed to
Conversion

Conversion is expected to eliminate $5.9 million in annual preferred dividend payments
and accretion charges and to increase annual net income applicable to common
shareholders by approximately $.11 per share

CLEARWATER, Fla.—December 29, 2006 —Think Partnership Inc. (AMEX:THK - News), an international leader in interactive performance-based marketing and related Internet technologies, announced today that the American Stock Exchange has approved the listing of shares underlying new warrants that will be issued in connection with the company’s previously announced conversion of $25 million in preferred stock into common stock. As a result, the conversion is now binding on all holders of preferred stock.

Think Partnership and its institutional holders had previously agreed, pursuant to separate legal agreements, to convert an aggregate of $25 million of Series A Convertible Preferred Shares into 12.5 million shares of common stock. The $2.00 per share conversion rate was established at the time the preferred stock was purchased by such investors in March 2006.

The approval by the American Stock Exchange to list the shares underlying the new warrants results in immediate conversion of approximately 25% of the preferred stock, while the remainder will convert over approximately the next 60 days. Preferred dividends have already stopped accruing for all of the preferred shares.

“The conversions will eliminate the entire $19.1 million of preferred stock from our balance sheet,” Think Partnership’s president and CEO, Scott P. Mitchell stated earlier this month upon receiving agreements from each investor. “More importantly, they will also eliminate an estimated $5.9 million in annual preferred dividend payments and accretion in the coming year. We expect the conversions to increase annual net income applicable to common shareholders by approximately $0.11 per share.”

Today Mitchell added, “American Stock Exchange approval and the resulting preferred stock conversion are great news for Think Partnership, especially as we wrap up a tremendous year of integration and growth, and prepare for another that we believe is even more promising.”
