This week on The Philanthropy Podcast, I highlight fundraising resources available to you that are research based and which cite their methods and sources. This episode came as a result of searching for annual appeal techniques that are backed by evidence and struggling to find them. We look at four main resources, The Science of Philanthropy Initiative, the Lilly School of Philanthropy, the Social Innovation Review, and NextAfter to examine what each offers, how they might be useful to you in your practice, and how we can all contribute to a more evidence based approach in our field.
