Hi, and no such thing as a dumb question. Where to send your survey link depends on where your marketing focus is. But the easiest is with your already made email list. How to get that email list? Well there are lots of ways and there are a bunch of articles on Kindlepreneur that show you each like through Facebook, Quora, forums, driving people from previous books of your to sign up, contacting other authors and asking them to send an email (although highly recommend becoming friends before asking a favor), etc…I hope that helps.
