Managing Director, Membership Acquisition Sierra Club
Facing the universal nonprofit challenge of measuring top-of-funnel digital impact, Sierra Club, America's largest and most influential grassroots environmental organization, wanted to test whether digital could truly complement direct mail without cannibalizing results. The answer was yes. It was a resounding success that delivered 230% growth in new online donors, 35% increase in sustainers, and 34% web revenue growth while direct mail performance remained strong. The secret was strategic audience modeling that identified three game-changing personas: Ready Donors (small but mighty revenue drivers), Persuadable (scalable growth engines), and Curious Clickers (future pipeline builders). Each segment required different creative and measurement approaches, and each delivered distinct, valuable outcomes.
This session will present real numbers and real frameworks that fundraisers can adapt immediately. The audience will learn how to build full-funnel segmentation using cooperative data and sustainer indicators, coordinate digital timing with mail for true incremental lift measurement, and structure pilots that evolve into annual programs. Whether you're digital-skeptical or ready to scale, you'll leave with proof points that convince leadership and tactical playbooks that drive results.
Learning Objectives:
Show how strategic digital segmentation drives measurable donor acquisition growth, including specific results from Sierra Club's three-persona model and frameworks for proving digital ROI to leadership.
Provide implementation roadmaps for testing and measuring digital impact without cannibalizing existing channels, including how to coordinate digital timing with direct mail for true incremental lift and structure pilots that can scale to annual programs.
Share methodologies for building and activating full-funnel audience segments using cooperative data and sustainer indicators, with appropriate creative strategies and success metrics for each funnel position from Curious Clickers to Ready Donors.
