Why SMS & WhatsApp Work So Well in India
Indian shoppers:
-
Check WhatsApp multiple times daily
-
Trust conversational messaging
-
Prefer quick updates
-
Respond faster to short messages
For repeat purchases, speed + familiarity = higher conversion.
Part 1: Smart Segmentation Before Sending Campaigns
Sending the same message to everyone reduces results and increases opt-outs.
Instead, segment customers into groups.
1. First-Time Buyers
Goal: Convert into repeat buyers
Send: Thank you + reorder incentive
2. Repeat Buyers
Goal: Increase loyalty & frequency
Send: Early access, VIP offers
3. Inactive Customers (30β60 Days No Purchase)
Goal: Reactivation
Send: Win-back discount or new arrival update
4. High-Value Customers
Goal: Relationship building
Send: Exclusive launches, premium support
5. COD Customers
Goal: Push prepaid adoption
Send: Small prepaid incentive
Segmentation increases conversions and reduces spam complaints.

In India:

Use approved message templates

Provide opt-out option
Example:
Reply STOP to unsubscribe.
3. Donβt Over-Send
Best frequency:

Avoid daily promotions
Trust is more valuable than short-term sales.
