Hi Tim,
Thanks for your interest! When a person choose a topic they will be put into a track that will send them a few emails on the topic they selected. When they are through with that track they will be placed into an evaluation program that looks to see if they selected another topic. If they did, they will enter another track for the new topic. Make sense?
We are pretty excited about it! Hoping we can get dynamic content to work for the initial confirmation email.
