What is the ROI of SMS marketing for a small boutique?

The economics of SMS marketing for boutiques are remarkably favorable. Klaviyo SMS for a small list costs about $15 per month, and texting 200 people costs roughly $4 per send, bringing your total monthly investment to around $19. Against that, a conservative flash sale scenario produces roughly $600 in revenue — over 3,000 percent ROI.

Even cutting every benchmark in half for a pessimistic scenario, you're still looking at about $300 on a $19 investment, which is nearly 1,500 percent ROI. Compare that to email, where click-through rates hover around two to four percent versus SMS at fifteen percent. The gap is enormous.

What makes these numbers even more compelling for small boutiques is that intimate customer relationships actually improve performance. Larger brands struggle to personalize at scale, but when you know your 200 VIP customers by name and buying preferences, your texts feel like personal notes rather than marketing blasts. That's a genuine competitive advantage that makes small-list performance often exceed industry averages.
