Case Study: San Diego Humane Society & SPCA achieves 513% growth in monthly sustaining donors and a 12% increase in retention with Blackbaud solutions

San Diego Humane Society and SPCA - Customer Case Study

San Diego Humane Society provides lifesaving care to nearly 50,000 animals each year across 12 cities and needed to scale quickly while deepening donor relationships. The organization faced challenges in building a sustainable monthly-giving program, improving donor retention, simplifying payment management, and creating a donor-focused, mobile-responsive website to drive engagement.

By implementing Blackbaud solutions—including Luminate Online, Raiser’s Edge NXT, Blackbaud Merchant Services (Credit Card Updater), marketing and analytics—the Society launched its Constant Companions sustaining program, redesigned its site based on supporter feedback, and blended face-to-face and digital fundraising. The outcome: 513% growth in sustaining donors over eight years, a 12% increase in retention, up to $75,000/month in sustaining revenue, recovery of 1,221 expired cards (>$58,000) and an estimated 200 staff hours saved, enabling continued growth in animals helped and fundraising scale.
