01.The Indian WhatsApp Advantage

While traditional email open rates in India average 18%–24%, official WhatsApp Business API broadcasts consistently maintain open rates above 88% and click-through rates higher than 25%.

However, treating WhatsApp like an aggressive SMS spam channel will quickly lead to account flaggings and brand reputation damage. The secret lies in behavioral conversational triggers.

02.3 Essential Automated Retention Flows

1. Interactive Abandoned Cart Recovery with 1-Click UPI Payment link.

2. VIP Restock & Post-Delivery Usage Guidance flow that drives repeat purchases before the customer runs out.

3. Milestone Gamification & Festival Loyalty rewards tailored to past spending tiers.
