This document summarizes a presentation about using online advocacy to acquire new donors for nonprofit organizations in a fast, cheap, and controlled manner. It discusses how Care2, an online community of engaged supporters, works with nonprofits to design advocacy actions and acquire multi-channel leads. When timely events occur, targeted emails to acquired supporters can successfully prompt donations. Examples are provided where calls to action around disasters raised thousands of dollars in donations at low costs. Optimization of post-action forms, welcome emails, and cross-promotion are also discussed to improve acquisition and fundraising results from online advocacy campaigns.
