The document discusses strategies for appending demographic and marketing data to fundraising lists to enhance fundraising efforts. It provides examples of how appending data on interests like fishing licenses or dog ownership increased response rates. Appending data on age, wealth, home value and contact information like phone, email and social media allows for more targeted fundraising, improved communications, and identification of prospective planned giving donors. Examples are given of non-profits that increased fundraising after implementing a data appending strategy to segment campaigns and engage donors through their preferred channels.
