WhatsApp Marketing for Businesses: Broadcasts, Catalogues and Automation Done Right
How Indian businesses use WhatsApp Business and the WhatsApp Business Platform for enquiries, catalogues, broadcasts and automation, without spamming customers.
Quick answer
WhatsApp works for marketing when customers choose to hear from you. Use the WhatsApp Business app for small teams with quick replies, labels and a catalogue; move to the WhatsApp Business Platform (API) for verified templates, automation, multiple agents and CRM integration. Collect clear opt-ins, send useful, personalised messages rather than blasts, use click-to-WhatsApp ads and website buttons to start conversations, and track replies, orders and opt-outs.
For many Indian customers, WhatsApp is the most natural way to talk to a business. They would rather send a message than fill a form or wait on a call. Used well, WhatsApp shortens the path from interest to order. Used badly, it becomes spam that gets you blocked. Here is how to use it properly.
App or platform: which do you need?
| WhatsApp Business app | WhatsApp Business Platform (API) | |
|---|---|---|
| Best for | Small teams, a few devices | Growing teams, high volumes |
| Catalogue | Yes | Yes |
| Quick replies and labels | Yes | Yes, plus automation |
| Approved broadcast templates | Limited | Yes |
| Multiple agents and CRM | No | Yes, through a provider |
| Chatbots and flows | Basic auto-replies | Full automation |
How do you start conversations?
Make it easy to message you from everywhere.
- A WhatsApp button on your website and contact page
- Click-to-WhatsApp ads on Instagram and Facebook
- QR codes on packaging, menus, bills and shopfronts
- Links in your Instagram bio and Google Business Profile
How should you collect opt-ins?
Ask clearly and record it. "Get offers and updates on WhatsApp?" with a checkbox or a reply keyword is enough. Only message people who agreed, and make opting out easy. Respecting consent protects your number and your reputation.
What should you send?
Messages customers would be sorry to miss.
- Order and booking updates: confirmations, reminders, delivery status
- Back-in-stock and new arrivals for products they viewed or bought
- Personal offers based on past purchases, not blasts to everyone
- Useful content: care tips, how-to videos, seasonal advice
- Follow-ups after an enquiry, with a clear next step
How do catalogues and automation help?
They let customers browse and buy inside the chat. Add products with photos, prices and descriptions to the catalogue. On the platform, automated flows can answer common questions, qualify enquiries and hand over to a person when needed. Keep a human available; customers notice when no one is there.
What mistakes should you avoid?
- Messaging people who did not opt in
- Sending daily broadcasts with the same offer
- Long messages without a clear action
- Slow replies to incoming enquiries
- No record of who asked what
How do you measure WhatsApp marketing?
Track replies, orders and opt-outs. Watch how many chats start from each source, how many become orders or bookings, response times, and how many people mute or block you after broadcasts.
How does WhatsApp fit with your other channels?
It is where conversations close. Social media and ads start interest, your website informs, and WhatsApp turns questions into orders. See Meta lead generation with Instagram ads and our marketing budget framework.

Frequently asked questions
What is the difference between the WhatsApp Business app and the API?
The app is free and suits small teams on one or a few phones. The WhatsApp Business Platform (API) supports approved message templates, automation, many agents and integration with CRMs and websites.
Can I send bulk WhatsApp messages to customers?
Only to people who have opted in, and through approved channels. Unsolicited bulk messages lead to blocks, reports and possible account bans.
How do click-to-WhatsApp ads work?
They are Meta ads on Facebook or Instagram that open a WhatsApp chat with your business instead of a website, which suits businesses that sell through conversation.
Is WhatsApp marketing effective in India?
Very, because most customers already use WhatsApp daily. It works best for enquiries, order updates, reminders and offers that customers asked for.
