WhatsApp has 500 million active users in India. It's the default communication app for the country. Yet most D2C brands treat it as a customer service tool, not a revenue channel.
That's the opportunity.
- Email open rate: 18-22% on a good list - WhatsApp message open rate: 90-98% - WhatsApp click-through rate: 45-60% - Email CTR: 2-5%
If you have 10,000 customers and you're running a sale: would you rather reach 1,800 of them via email or 9,500 via WhatsApp?
1. Abandoned cart recovery A customer added your product and didn't buy. Send them a WhatsApp message with a photo, the product name, and a direct link. Not 24 hours later, within 15 minutes. Conversion rates on these messages can hit 20-35% for warm audiences.
2. Post-purchase sequence Day 1: "Your order is confirmed. Here's what to expect." Day 3: "Your [product] is on its way! Here's your tracking link." Day 7: "Your [product] should have arrived. How is it?" Day 21: "Loved it? Here's 15% off your next order."
This sequence costs almost nothing to set up and dramatically increases repeat purchase rates.
3. Restock and launch alerts Build an opt-in list of customers who want early access to new drops or restocks. When you launch, message them first. These buyers convert at 3-4x the rate of cold audiences.
4. Win-back campaign Customers who haven't bought in 90+ days. A single WhatsApp message with a personal note and a time-limited offer can recover 8-15% of lapsed customers.
