Without a doubt, the most effective use of e-mail as a marketing tool is the often-overlooked category of response e-mails. These are e-mails sent to people in response to requests for information, to orders being placed, to visits to a company’s website based on specific pages being visited, to actions taken in other e-mails and even to calls made to the call center. And these are the highest-responding e-mails a company will ever send out. http://ping.fm/oBkFA
