Hello Fynn - because Unbounce hosts your pages, you do not need a hosting service. You should be able to make the necessary changes to your DNS settings through your domain registrar. All you need to do is create a CNAME record for the subdomain you would like to use and point it to ‘unbouncepages.com’. We have an article that outlines the necessary steps at http://support.unbounce.com/entries/2…

You can also find CNAME set up instructions for many common hosting providers in our knowledge base at http://support.unbounce.com/forums/25…

Hope that helps!
