How VETAIN Achieved a 33.9x ROI with a WhatsApp Restock Campaign

Challenge

VETAIN, an innovative brand in the sustainable lifestyle space, faced a common challenge: How can restock announcements be communicated in a way that maximizes attention and drives purchases?

Traditional email announcements and social media posts reached parts of the community but often got lost in the noise. The goal was to achieve clear messaging, high reach, and direct conversions in a short time.

Solution

With Chatarmin, VETAIN launched a WhatsApp Restock Campaign for its summer collection.

Key success factors:

• . Direct channel – customers received the restock announcement instantly via WhatsApp.
• . Concise, clear messaging – communication focused on exclusivity and scarcity (“Now back in stock”).
• . Fast checkout – direct purchase links led straight to the shop without detours.

This setup conveyed both urgency and exclusivity, motivating the community to act immediately.

Results

The campaign delivered impressive results:

• WhatsApp revenue: €44,469.48
• WhatsApp costs: €131.51
• Return on WhatsApp Spend (ROWS): 33.9x
• Conversion rate: 4.7%
• Average Order Value (AOV): €74.49

Conclusion

The VETAIN case demonstrates how restock campaigns via WhatsApp can be scaled effectively.

With a single action, the brand generated over €44,000 in revenue, achieved a 33.9x ROI, and once again proved that WhatsApp is the fastest and most direct channel for e-commerce performance.
