Challenge
Duschbrocken, the sustainable brand for solid shower and care products, wanted to boost revenue with a targeted campaign while at the same time streamlining the customer journey.
The goal was to achieve maximum revenue, high conversion rates, and clear measurability with a single campaign – without relying primarily on discounts.
Solution
With Chatarmin, Duschbrocken launched a WhatsApp sales campaign aimed directly at its existing community.

Key success factors:
- Relevant targeting – existing contacts were reached with clear, personalized messages.
- Direct purchase incentive – simple checkout links led to seamless conversions without friction.
- High reach – WhatsApp enabled the brand to reliably activate almost the entire recipient list.
Results
The campaign significantly exceeded expectations:

- WhatsApp revenue: €63,304.20
- WhatsApp costs: €3,893.35
- Return on WhatsApp Spend (ROWS): 16.3x
- Recipients: 17,869
- Orders: 1,293
- Revenue per recipient (RPR): €3.54
- Conversion rate: 7.2%
Conclusion
This second Duschbrocken case once again highlights the power of WhatsApp campaigns in e-commerce.
With just one campaign, the company generated over €63,000 in revenue, achieved a 16.3x ROI, and recorded nearly 1,300 orders – clear proof that WhatsApp is a key performance channel for brands like Duschbrocken.
