This document provides guidance on how to identify and engage major donors. It defines major donors as those who give $10,000 or more, as they contribute 64% of total fundraising dollars. It recommends investigating potential major donors based on 5 markers of philanthropy: giving to your organization before, giving to other organizations, being a trustee of a grant-giving foundation, owning high-valued real estate, and making political gifts. Donor-advised funds are another source of major donations, with over $15 billion granted from these funds to charities in the last year. When engaging major donors, communications should answer how much a project needs, what the donation will fund, and what the expected end result will be.
