I also use Aweber
to send out automated followup emails. I think this company has one of the best value for money services available for online email marketing.
Here's the deal, you can try Aweber on a 30 day full money back guarantee and they also give you access to a two-part video of Jonathan Mizel's sequential autoresponse seminar in London, England, plus lots of other resources for getting the most out of email marketing.
If you are wondering who Jonathan is, he has worked with industry giants like Disney, Microsoft, Intel, and American Express who have used his expertise for targeted opt-in e-mail.
* Totally unique ways to use AWeber autoresponders
* Two case studies of doubled, even tripled profits
* Secrets of super-marketers like Marlon Sanders

This video puts thousands of dollars worth of intellectual material at your fingertips.
