To grow an email list with Facebook Ads, the first step is to create a clear offer that gives people a reason to sign up. This could be a free guide, a checklist, or a helpful tool related to the affiliate product you're promoting. Then, you create a landing page where people can enter their email to get the offer. On Facebook, you can target people by age, location, interest, and more, so your ad reaches the right audience. Keep the ad simple with a clear headline, a short description, and a strong image. Always test different versions to see what works best. Once people sign up, you can start sending them helpful emails and introduce the affiliate product later. This way, you build trust first before promoting anything. Have you tried using Facebook Ads before to build a list for affiliate marketing?
