What is it?

I don't know why all these autoresponder/mailer services assume it is so easy that no explanation is necessary. These things are a college course of information and they would be worth the money. Let's have some basic training. Let's have a couple of pages answering the questions: What is it? What is it for? What does it do? Millions of people are told they need one, but when you go to pick one, you get a couple of miniature screenshots. What's a campaign? How do I know if it's working? What did it send? Why didn't it send?

These Autoresponder Outfits want a lot of money. Personally I want them to do a much better job of answering these questions and a lot more of them.
