Here's a link for purchase of a Dedicated IP from GoDaddy. It's a good thing to have, especially on shared hosting.
I would recommend steering away from Mailchimp personally. I'm not sure if you're paying for it but I use GoDaddy Email Marketing and it doesn't slow down my site because there's nothing to install and it's much easier to use and integrate.
