Sending different welcome emails based on sign up form?

I'm currently working on a side-hustle and I'm running into a view technical challenges with mail chimp.
1. Is it possible to send a different welcome email with the same list? Or do I have to create a new list for that? The reason behind that question is I have different opt-in forms with free tools and ebook as an exchange for their email.
2. If an email is already subscribed to my list and they do sign up for a free ebook or a different kind of offer. They will see this message "This email address is already subscribed, thank you!" Is there a way to redirect already subscribed emails to another Page, like a bonus area or a certain page?
