Indian SMBs lose ₹4.7 lakh crore annually to abandoned carts and cold leads (NASSCOM Q1 2026). WhatsApp retargeting recovers 43% of these when done right—without bans. The difference? Smart automation for opted-in leads only, using Meta Coexistence API (App + API = free messaging).

This guide shares the 7-step framework D2C brands, coaches, and agencies use to hit 64% reply rates safely. No hype, just proven plays that work in 2026.

Core Debate: Bulk blasts (17% ban rate) vs Smart retargeting (0.2% restrictions)?
