Does anybody know of good resources or classes to learn email strategy and marketing? So far I have spent all my time doing the development and design. While I really love that side of email, my company is offering to pay for any courses or anything really that invloves the marketing and strategy side of email. Even if I continue more in development I think this would be a great thing to know and can only open the door to more career opportunities in the future.

Also I realize that Litmus and other blogs are a great resource however I'm specifically looking for courses you can take. At the very least any advice from those here who are very savvy in email marketing. Thanks!
