Do the leads get a follow up?

Ok,

So when I send traffic to the Clickbank sales page, the user is asked to enter an email.

Do I get access to the email list, or does a follow-up email gets sent out automatically?

This is where I am sending traffic - https://buildasuccess.info/

And you see if you follow the funnel you get led to an opt-in form where the user needs to enter email.

Where do these email addresses get stored?
