Short answer: do not use unofficial bulk-sender software or WhatsApp Web tools. They get numbers banned. Use the official WhatsApp Business API through a Meta-approved provider, send only to customers who have opted in, use Meta-approved message templates, and keep messages useful and relevant. You pay a small per-message fee to Meta, and your number stays safe.

WhatsApp is the most-read channel in India, which makes it the best place to reach customers with offers, reminders and updates. But WhatsApp is strict about spam, and getting it wrong can cost you the number your customers know.

Why numbers get banned

  • Using unofficial "bulk WhatsApp" software, browser extensions or modified apps
  • Messaging people who never gave you their number or did not agree to receive messages
  • Sending the same message to hundreds of people from the normal WhatsApp Business app
  • Many recipients blocking or reporting you
  • Sharing purchased or scraped number lists

Once a number is banned, the chats are gone and getting it back is not guaranteed.

WhatsApp Business App vs WhatsApp Business API

  • WhatsApp Business App (free): fine for one-to-one chats and small broadcast lists, where only people who saved your number receive broadcasts
  • WhatsApp Business API (official, paid per message): built for sending to thousands of customers, automation, chatbots, CRM integration and team inboxes

For bulk messaging, the API is the only safe option. Read our detailed comparison: WhatsApp Business API vs App.

Step-by-step: send bulk messages the safe way

  1. Get the WhatsApp Business API through a Meta Business Partner. You need a Meta Business account and a phone number not already active on WhatsApp (or migrate your existing one).
  2. Verify your business in Meta Business Manager for higher limits and a trusted profile.
  3. Collect opt-ins: website form checkbox, click-to-WhatsApp ads, QR codes in store, or customers messaging you first. Keep a record.
  4. Create message templates (marketing, utility or authentication) and submit them for approval. Use variables like the customer's name and order number.
  5. Segment your list: past buyers, new leads, city, interests. Relevant messages get fewer blocks.
  6. Send the campaign from the provider's dashboard and track delivered, read and clicked.
  7. Handle replies in a shared team inbox or with a chatbot.

Costs

The API platform or provider may charge a monthly fee, and Meta charges per message, with different rates for marketing, utility and authentication messages. In India, marketing messages typically cost under ₹1 each. Check Meta's current rate card, as prices change. Utility messages, such as order updates, are cheaper.

Best practices that keep your quality rating high

  • Send 2–4 marketing messages a month, not every day
  • Make every message useful: a real offer, a reminder, new arrivals
  • Add buttons (Shop now, Call, Book) rather than long text
  • Include an easy opt-out ("Reply STOP to unsubscribe") and honour it
  • Watch your quality rating in Business Manager. If it drops, slow down and improve targeting

Meta also limits how many marketing messages one person receives from all businesses, so some messages may not be delivered to very active users. That is normal.

Frequently asked questions

Can I send bulk messages from the normal WhatsApp app?

Only through broadcast lists to people who have saved your number, with a limit per list. Mass sending from the app risks a ban.

Sending promotional messages to people who opted in, through the official API, is allowed. Messaging bought lists breaks WhatsApp's rules and can breach Indian privacy and telecom rules.

Can I use my current business number?

Yes. The number can be moved to the API. Once moved, it is managed through the API platform instead of the regular app.

Do you set this up?

Yes. We handle WhatsApp Business API setup, templates and opt-in flows, and run monthly campaigns with our WhatsApp & email marketing service.
