Constant Contact (NASDAQ: CTCT) launched its IPO back in early October, and the stock is since up about 35%. The company provides on-demand email marketing solutions primarily to small businesses.
Now, investors will have another email play -- ExactTarget has filed for an IPO.
However, ExactTarget's services are focused more on medium- and large-sized businesses. Some of the customers include Expedia.com, Florida Power and Light, USA TODAY, Liberty Mutual Group, Papa John's and Wellpoint (NYSE: WLP).
