Why it works
The story leads with a number going up (632% ROI, $34K donation lift) which locks it as Breakthrough over Efficiency, despite the operational consolidation subplot. The competitive switch from Constant Contact is named explicitly and tied directly to the capability gap that drove the decision. The nonprofit context adds a mission layer that makes the results feel meaningful beyond raw revenue.
Steal this
Anchor the ROI claim to a specific campaign window (Fall 2025 drive) rather than an annual average, which makes the number feel auditable and hard to dismiss.
