Cause marketing has emerged as a powerful strategy for brands looking to drive product sales while supporting meaningful societal issues. In this case study, we examine a successful cause marketing campaign tied to a product purchase, demonstrating how strategic partnerships can benefit both business and community. Read on to discover insights you can apply to your own brand’s purpose-driven campaigns.
The Power of Cause-Related Marketing: Driving Impact Through Collaboration
Cause-related marketing leverages a collaboration between a for-profit business and a nonprofit organization, linking the sale of a brand’s product to support for a charitable cause. The adoption of these campaigns has risen sharply as consumers actively seek brands with a social conscience. According to a 2025 Sprout Social report, 72% of consumers say they are more likely to purchase from brands committed to social responsibility.
Effective cause marketing combines authenticity, transparency, and measurable impact. Brands that successfully align with causes their customers genuinely care about not only increase sales but also earn long-term loyalty. A recent Edelman Trust Barometer survey in 2025 revealed that 74% of Gen Z and Millennials expect brands to take a stand on social issues. Thus, the right campaign can become a driving force for both business growth and positive societal change.
Case Study Overview: The “Clean Water for All” Campaign
Let’s examine a real-world example — the “Clean Water for All” campaign launched by AquaPure, a leading bottled water company. In early 2025, AquaPure partnered with WaterAid to deliver clean water to underserved communities worldwide. For every bottle sold, AquaPure pledged to donate the equivalent of one day’s clean drinking water for a person in need.
This initiative was not only tied directly to product purchase, but also featured transparent donation tracking, shareable impact stories, and clear in-store and online messaging. The campaign ran from January through June 2025 across over 8,000 retail locations and major e-commerce platforms.
Strategic Planning: Aligning Product, Purpose, and Audience
AquaPure’s choice of cause was informed by consumer insights and brand values. Clean water aligned naturally with their product, reinforcing authenticity. The company conducted pre-campaign surveys and found that 68% of their target customers identified safe water access as a top global concern.
Key strategic elements included:
- Thorough nonprofit vetting: WaterAid was selected for its proven impact and transparent reporting.
- Clear communication: All marketing materials explained how each purchase directly supported water donations.
- Scalable donation model: Pledging donations per unit sold allowed for easy tracking and ensured tangible results for every customer.
By aligning their product with a relevant cause, AquaPure created an authentic narrative that resonated with conscious consumers, opening new customer acquisition channels.
Execution: Promotion, Engagement, and Reporting Transparency
The campaign’s success was built on robust execution and credible communication. AquaPure utilized a blend of digital and in-store marketing, including:
- Social media storytelling featuring real beneficiary communities
- QR codes on bottles leading to live impact dashboards
- Email updates informing customers of the campaign’s progress
- Strategic influencer partnerships amplifying the cause
- In-store signage and staff training to effectively communicate the campaign
Transparency was a top priority. Weekly progress reports detailing water delivered, communities reached, and donor spotlights appeared on AquaPure’s and WaterAid’s websites, as well as across social channels. Customers could trace their individual impact, promoting a sense of collective achievement.
Results: Sales, Impact, and Brand Perception Growth
The “Clean Water for All” campaign delivered measurable results:
- Sales impact: During the six-month campaign window, AquaPure saw a 27% increase in product sales compared to the same period in 2024.
- Community benefit: Over 1.3 million people gained access to clean drinking water for at least one day thanks to consumer purchases.
- Customer engagement: The campaign generated over 540,000 hashtag uses and tens of thousands of unique QR code scans.
- Brand perception: Independent post-campaign surveys showed a 34% improvement in positive brand sentiment among shoppers aware of the campaign.
These outcomes demonstrate how a well-planned, transparent cause marketing strategy can drive both tangible business growth and significant societal good. Stakeholder trust was bolstered through transparent donation tracking and third-party verification of results.
