I have an email course (autoresponder) -> course sales funnel setup for Double Your Freelancing Rate which nets about $1-1.5k a day in sales, mostly on autopilot. This is by far the most successful funnel I've created for any of my products, and is performing really stinkin' well. Product: http://doubleyourfreelancing.com/rate/ Email course: http://doubleyourfreelancing.com/free-pricing-course/
So if anyone else is thinking of setting up this kind of autoresponder email course, make it valuable. I've been through a bunch of these kind of deals and there is a lot of crap out there.
