Thanks for these really helpful suggestions, Peter!We are planning to test some of things you suggest. We kept our post-donation survey short because we wanted to focus on our main research question and not try to do too many things at once. But if we end up having a lot of donors, we might send them a survey via email to find out more about their demographics, beliefs and preferences. We’re not planning to do A/B testing at this point. But if we’re starting to get lots of donors, we’d definitely consider doing A/B testing to optimize the user experience and get more people to donate.At this point, our primary goal is to test if the technique works in the real world and if we can get enough donors. Yes, we want to do media releases to get more traffic. And we are trying to partner with organizations and services to spread the word. I like your idea of reaching out to workplace giving services. If you have concrete ones in mind or have ideas how I could find these, please shoot me a DM!
