Ask What’s the best strategy for pre-launching a membership site?

[SuperAffiliateX]

I want to launch a membership site, but I'm not sure how to build interest before it goes live. I've heard that a pre-launch strategy can help attract members early. Should I create a waitlist or offer early sign-up bonuses? Do I need to run ads, or is social media enough? I don't want to spend too much, but I also want people ready to join on day one. What steps should I take to make the pre-launch successful?
