That’s just one of the basic premises of our new book Start Over explores. The problem with getting the manuscript off to the publisher is that new research findings keep coming in. So, another chapter or two have to be re-written. Let me explain. In preparing my earlier book, Retention Fundraising: the art and science of keeping your donors for life, I kept the promise to myself that I’d avoid tribal wisdom and so-called ‘best practices’ in favor of recommendations based solely on empirical research. I did. And used 3 years of research conducted by DonorVoice on 250+ U.S. and UK charities.
