Campaign on campaign comparison highlights a step-change in performance after switching providers & targeting solutions.
The Challenge: Improving Appeal Performance
A 2024 door drop cash appeal produced disappointing results for the NSPCC. The fundraising team sought an improved door drop approach to raise money for their 2025 Christmas Appeal.
The Solution: Smarter Audience Targeting
The solution from Whistl was a bespoke and efficient targeting model that blended 1st party donor data and modelled inputs. Thoroughly back-tested to prove discrimination, resulting in an optimal 2025 Cash Appeal.
The Results: Stronger Response & ROI
Improved efficiency and response rates suggest better optimisation, audience segmentation, and delivery strategy.
Overall, the uplift clearly reflects a more advanced and effective targeting solution, outperforming the competitor by recruiting donors at a cost of 75% less.
Working with Whistl brought valuable expertise to our 2025 Christmas Appeal. Their advanced targeting and delivery strategy complemented our creative approach, driving improvements in landing our message to our audiences with increased precision. As a result, we’ve seen year on year gains in efficiency and return, with the partnership providing us with a strong foundation to build on for future campaigns
