If you're a little scared of Facebook Ads, then I suggest you start with the people who are already familiar with you.  Those are the people who are on your email list.  It takes less than 5 minutes of time to complete for you to have an audience that is a great way to test what ads will resonate with your golfers.

Put this on your calendar to upload at least once a month.  Your email list doesn't automatically upload into Facebook without you going through this procedure.
