WhatsApp Marketing for Small Businesses: What’s Allowed and What Gets You Banned?
Quick answer: WhatsApp marketing for small business works best when people have opted in, your messages are relevant and you follow WhatsApp’s business policies. Use the WhatsApp Business App for simple, personal messaging or the WhatsApp Business Platform for approved templates at scale. Spam, bulk messaging without consent and misleading content can get your number blocked.
In India, WhatsApp is where customers already talk. That makes it powerful for enquiries, follow-ups and repeat sales, and risky if used carelessly.
WhatsApp Business App vs Business Platform

|---|---|---|
| Best for | Small teams, simple chats | Larger volumes, automation, CRM integration |

| Cost | Free to use | Usually through a provider, with message-based charges |
| Broadcasts | Limited to contacts who saved your number | Template messages to opted-in users |
Pricing and rules change, so confirm current details with Meta or an official provider.
