Wow. Marketing email software provider ExactTarget has secured another $70 million in funding, according to an SEC filing, bringing the startup's total funding this year alone to $145 million. The company raised $70 million earlier this year from Battery Ventures, Scale Venture Partners and Montagu Newhall. Not too shabby considering the state of the economy.
