newsletter

I need a newsletter that can be different by argoments…so if someone is interested in animals can put the check to animals and he will received only the newsletters about animals, but if he puts the check on animals and planets, he will receive the newsletter about animals and the newsletter about planets. Sorry for my english, I’ve tried to explain me. Can you tell me if I can do it with the basic version of Mailchimp or I have to by the add-ons? Thanks! And If someone is downloading something is possibile to put with Mailchimp the possibility to download the pdf only if you previously subscribe to the newsletter? Thanks!
