This guide outlines strategies for a small animal shelter aiming to improve its donor retention rates (DRR). The shelter operates on a budget of $200,000 and primarily relies on local donors, many of whom contribute small, one-time gifts during annual pet adoption events. The current DRR is 30%, which is below the industry average. The document presents a challenge of high attrition among first-time donors, who often do not return after emotional adoption events. To address this, the shelter aims to increase its overall DRR to 35% and first-time donor DRR to 20% by the end of 2025. Strategies include implementing a welcome series for new donors, sending personalized thank-you notes, sharing impact updates through newsletters, and encouraging recurring donations. The document also details tracking methods using a CRM system and Google Sheets to monitor progress and assess the effectiveness of these strategies. By mid-2025, the shelter has seen improvements in donor retention, achieving its targets by the end of the year.
