This document discusses strategies for nonprofit donor retention. It begins by providing statistics showing declining retention rates over time. Reasons donors stop giving include no longer being able to afford it and poor communication. Factors that increase retention are timely thank you's, informing donors how gifts are used, and soliciting feedback. The document recommends segmenting communications based on giving amount and frequency. Personalizing acknowledgements, especially for first-time donors, and surveying donors are also emphasized. The key is focusing on stewardship before soliciting additional gifts.
