Noonan's last day with AIM was Friday. DMA spokesman Louis Mastria said the association is actively looking to fill the position.
"Kevin's tenure at AIM was spent developing and driving industry standards for online marketing," said Matt Blumberg, CEO of Return Path. "We are delighted that he will now use his considerable knowledge and experience to help optimize the e-mail performance of future Return Path clients."
Noonan was previously VP-Internet media and research at the Yankee Group, and before that senior VP and partner at @plan.
