This document discusses in-memory donations to charities. It notes that in-memory donations are growing faster than legacy donations. However, many charities are not adequately acknowledging or following up with in-memory donors. The document analyzes data on response times and volumes of communications from various charities in different countries to in-memory donors versus other donors. It finds that in-memory donors generally receive less and slower responses. The document advocates for charities to collect donor data appropriately, provide more personalized responses to in-memory donors that are sensitive to their grieving process, and give donors more control over the relationship.
