The average Indian D2C brand spends ₹800–₹2,400 to acquire each customer through paid ads. Then they send that customer a generic order confirmation email — and never contact them again. Repeat purchase rates sit at 14–18% when they should be 35–45% for a healthy D2C business.

Klaviyo changes that. Every customer who buys from your Shopify store enters an automated journey — a post-purchase series that educates and builds trust, a replenishment reminder timed to when they'll run out, a win-back sequence if they go quiet. Revenue that runs while you sleep, on customers you already paid to acquire.

For most D2C brands, Klaviyo generates 25–35% of total revenue within 90 days of a proper setup — at a fraction of the CAC of paid acquisition. It's the highest-ROI channel available to a D2C brand that already has customers.
