How Did You Promote Your Affiliate Marketing Partnership?

We just started ourAffiliate Marketing Partnership, but we haven't dived in on what should we do to encourage people to join. The criteria is to create an affiliate link, and earn $20 for every logo sale they made. Do you guys think it's enough, or we should add more benefits? And what should we do to encourage users to join? So far, we only did a internal and guest blog, and post on slack communities about the partnership as well. Within the week, we're planning to promote them on our social media accounts as well. Any further suggestions is much appreciated.
