Tested a paid group tier for my non-buying audience

I ran a test with my list: a small paid group cohort at KES 2,500 a month, capped at 12 people, pitched in the same email that gets opened and ignored. Got 4 signups in the first week, which is not nothing but also not the 20 I quietly hoped for. I think the problem is not price, it's that my free stuff answers the question, so nobody has a reason to pay for the next step.
