Challenge
VETAIN, the sustainable lifestyle brand, had already used WhatsApp successfully for restock announcements. For the 2023 summer restock, the goal was to once again prove that WhatsApp is unmatched when it comes to efficiency, reach, and conversion.
The challenge: channel high demand and quickly turn it into measurable sales.
Solution
With Chatarmin, VETAIN launched a WhatsApp Restock Campaign that directly informed its community.
Key success factors:
- Direct channel – restock announcements landed straight in recipients’ WhatsApp inboxes.
- Exclusivity – messaging created urgency and scarcity (“Only while supplies last”).
- Clear purchase impulse – direct shop links enabled fast conversions.
What makes this case especially impressive: all results came from a single campaign sent to a five-figure audience.
Results
The campaign delivered outstanding results:
- WhatsApp revenue: €18,026.05
- WhatsApp costs: €313.91
- Return on WhatsApp Spend (ROWS): 57.4x
- Average Order Value (AOV): €92.92
- Revenue per recipient (RPR): €5.81
- Conversion rate: 6.3%
- Campaign setup: 1 campaign sent to a five-figure audience
Conclusion
The VETAIN case demonstrates that WhatsApp restock campaigns are a highly profitable tool for e-commerce brands.
With just one campaign, the brand generated over €18,000 in revenue, achieved a 57.4x ROI, and reached a 6.3% conversion rate – clear proof of WhatsApp’s effectiveness as a performance marketing channel.
