285.2x Return on WhatsApp Spend with a Welcome Flow at Rain Couture

Challenge

Rain Couture from Amsterdam stands for stylish, weatherproof fashion. The brand targets urban customers who value both design and functionality, even on rainy days.

Like many fashion brands, Rain Couture faced a central challenge: How can we engage first-time buyers immediately and maximize basket value – without relying on expensive retargeting campaigns?

Email welcome flows delivered solid but uninspiring results. Open rates and conversion rates remained below industry expectations.

Solution

With Chatarmin, Rain Couture implemented an automated WhatsApp Welcome Flow – the most direct way to welcome new customers.

The flow followed a simple yet effective structure:

• . Instant greeting – new customers received a personal WhatsApp message right after their purchase.
• . Product value – styling tips, care instructions, and inspiration for using Rain Couture’s high-quality products.
• . Upsell and cross-sell – tailored recommendations for matching accessories and styles. Setup took only a short time – but the impact was long-lasting.

Results

The results were exceptional:

• WhatsApp revenue: €3,678.95
• WhatsApp costs: €12.90
• Return on WhatsApp Spend (ROWS): 285.2x
• Average Order Value (AOV): €459.87

Rain Couture not only achieved a record ROI but also significantly boosted its average order value. WhatsApp became the most effective performance channel in their marketing mix.

Conclusion

The Rain Couture case proves that properly set up welcome flows are revenue engines.

With minimal effort, the brand achieved a 285.2x return on spend while pushing the average order value to over €450.
