Monetization Strategy for My Directory

Hey, I just enabled monetization for my directory, https://www.findsurfcampbali.com/ .

I’m wondering about the best approach before reaching out to surf camps via cold email. Should I: 1. Remove all current listings before contacting them, so they need to pay the $59 fee to get listed? 2. Keep all listings live and mention in the email that they will be removed unless they purchase a paid listing?

Which approach do you think would be more effective? Would love to hear your thoughts!

Best, Andri
