WhatsApp has a 98% open rate. No other marketing channel in India comes close — not email (20% open rate), not SMS (45%), not social media. If you're a business in India and you're not actively using WhatsApp for marketing, you're leaving revenue on the table every single day.
Why WhatsApp Marketing Works So Well in India
India has 853 million WhatsApp users. It's the default messaging app for almost every age group and income bracket.
Key advantages:
- 98% open rate — almost everyone reads your message
- Native payments — collect payments directly in the chat
- Rich media — images, videos, PDFs, voice notes, location pins
- Conversational — customers reply, ask questions, and buy in the same thread
- No algorithm — your message reaches every opted-in contact, unlike social media
Getting Started: Official WhatsApp Business API
There are two types of WhatsApp for business:
WhatsApp Business App — for solo founders and small businesses. Free, but limited to one user, no campaigns, no API.
WhatsApp Business API (Cloud API) — for teams and marketing. Supports multiple agents, bulk campaigns, chatbots, and automation. Requires official approval from Meta.
For serious WhatsApp marketing, you need the Cloud API. You can get access through a BSP like WhatsGrow AI, which handles the setup for you.
WhatsApp Campaign Types That Convert in India
1. Promotional broadcasts: Send offers, discounts, and product launches to opted-in contacts. Best days: Tuesday-Thursday, 10am-12pm IST or 7-9pm IST.
2. Abandoned cart recovery: Trigger an automated message 1 hour after cart abandonment. Average recovery rate: 15-25%.
3. Lead nurture sequences: Send a WhatsApp sequence: introduction, case study, offer, follow-up. Outperforms email 3x.
4. Appointment reminders: Automated reminders cut no-show rates by 40-60%.
5. Post-sale follow-up: Ask for reviews, upsell products, collect referrals. WhatsApp NPS campaigns get 5x higher response rates than email.

WhatsApp Marketing Compliance in India
You must follow Meta's messaging policy or your number will be banned:
- Only send to users who have explicitly opted in
- Use only approved message templates for outbound campaigns
- Provide an easy opt-out option in every campaign
- Do not send bulk promotional messages to cold contacts
WhatsGrow AI handles template management and ensures your campaigns comply with Meta's policies automatically.

Track these metrics in your WhatsApp CRM:
- Delivery rate — should be 95%+
- Read rate — should be 70-90%
- Reply rate — how many contacts engaged
- Lead conversion — how many replies converted to pipeline deals
- Revenue per campaign — track Razorpay payment links back to campaigns
