WhatsApp is one of the most direct ways to reach customers in India, and Meta has been adding business tools, including AI support for small businesses, that make it more useful. It is also easy to misuse. Done badly, it annoys people and risks your number being restricted. Done well, it brings faster replies, repeat orders and trust. This guide covers the basics.
Check current rules: WhatsApp's policies and pricing change from time to time. Confirm the latest terms and rate card in Meta's documentation or with your provider.
Start with consent
- Only message people who opted in to hear from you on WhatsApp.
- Collect consent clearly: a checkbox on your website or form, a click-to-WhatsApp ad, a QR code in store, or a customer starting the conversation.
- Say what you will send and how often.
- Make opting out simple, and honour it right away.
- Keep records of consent. India's data protection law also expects clear consent and notice.
Know the two kinds of conversation
- Customer-initiated: a customer messages you, and you can reply freely for a limited service window.
- Business-initiated: you message first. This generally needs an approved message template, and sending is charged according to Meta's current pricing.
Using the WhatsApp Business Platform (the API) rather than the basic app is what lets you send templates at scale and connect chatbots, CRMs and ERPs.
Content that works
- Order and delivery updates, which customers actively want
- Appointment and payment reminders
- Abandoned cart nudges, sent sparingly
- Back-in-stock and restock alerts for people who asked
- Festive offers and new arrivals for opted-in customers
- Product catalogues and quick replies for common questions
- Feedback requests after a purchase
Click-to-WhatsApp ads
These ads on Facebook and Instagram open a WhatsApp chat instead of a website. They suit businesses where a conversation closes the sale, such as real estate, education, clinics, jewellery and services. Tips:
- Pre-fill a friendly first message.
- Reply within minutes during working hours.
- Qualify leads with two or three quick questions.
- Track which ads create conversations that become sales.
Do's and don'ts
Do
- Keep messages short, useful and personal
- Use the customer's name and relevant details
- Send at sensible hours
- Offer a human option
Don't
- Buy phone number lists
- Send the same promotion to everyone
- Message too often
- Hide your business name or purpose
Measure what matters
Track delivery and read rates, replies, opt-out rate, leads created, sales and revenue per message. A rising opt-out or block rate is a warning sign.
Connect it to your systems
Linking WhatsApp to your CRM or Odoo means a lead is never lost, follow-ups are automatic and your team sees the full history. Adding an AI assistant can handle common questions around the clock, with a smooth hand-off to a person.
