The festival offer, the new-batch announcement, the restock alert: for an Indian business, the broadcast is how one message reaches the whole customer base while arriving as a personal chat. Recipients never see each other, replies come back one-to-one, and nothing marks the message as bulk.
Broadcasts also fail silently more often than any other WhatsApp feature, and misused ones get business numbers restricted, with block-and-report habits strong among Indian users. This guide covers the mechanics, the delivery rule that empties most lists, and how to send at Diwali-season volume without tripping the spam systems.
Broadcast lists: the mechanics
A broadcast list is a saved set of recipients. Sending to the list delivers a separate private message to each person, like BCC in email: no shared thread, no visible recipient list. A group is the opposite, one room where everyone sees everyone, numbers included.
Replies land in your normal one-to-one chat with that customer. Nobody can tell a broadcast from a personally typed message, which is exactly why a well-written broadcast performs like a personal note.
Creating and sending one
- 1
Open broadcast lists
Android: three-dot menu, New broadcast. iPhone: Broadcast lists above Chats, then New list. Identical in the WhatsApp Business app.
- 2
Select up to 256 contacts
Only numbers saved in the phone contacts can be added. Segment customers across several lists: regulars, this month’s enquiries, wholesale buyers.
- 3
Send like a normal chat
The list sits in Chats. Text, images, catalogue items, PDFs of price lists, voice notes: everything goes out as individual private messages.
- 4
Edit any time
Open the list, tap its name, add or remove people. Lists are reusable.
Lists are created and managed on the phone. From WhatsApp Web you can continue the conversations that replies open, but list creation and list sends stay in the mobile app.
The save-my-number rule: why broadcasts vanish
A broadcast is delivered ONLY to recipients who have saved your number in their contacts. Everyone else silently gets nothing: no error for you, no notice for them. This is WhatsApp’s built-in spam brake, and it is the answer to almost every "customers did not get my message" complaint.
The practical consequence: the ask-them-to-save-you habit is worth more than any list-building trick. A QR code at the billing counter, a wa.me link in the Instagram bio, a line on the invoice: each one turns saving your number into a one-tap action, and each saved contact is a customer your broadcasts can actually reach.

Scaling up: Business app, API, or linked-device tools
The free WhatsApp Business app gives the same 256-contact lists plus labels and quick replies. A boutique announcing a sale to a few hundred regulars can run this by hand.
The WhatsApp Business API is the official high-volume lane most large Indian brands use for notifications: pre-approved templates, per-message pricing, a separate dedicated number, and no save-my-number requirement. It suits transactional traffic at scale, at per-conversation cost and with an approval process.
Between the two sit linked-device tools such as Spun, which connect to your existing number the way WhatsApp Web does and add campaigns on top: audience lists you define, no save-my-number requirement, deliberately paced sending that stays inside safe limits, and flat monthly pricing instead of per-message fees. Replies land in a shared team inbox with full history.
Festival-season sending without getting banned
- Consent first: message people who expect to hear from you. Bought databases and cold blasts are what the report button exists for, and Indian users use it.
- Frequency discipline: one useful update a week survives; daily offers train customers to block, and blocks plus reports are what restrict business numbers.
- Write personally: broadcasts arrive as private messages, so a "Namaste Sharma ji" tone beats a poster dump.
- Honour opt-outs instantly: "Reply STOP to unsubscribe", and actually remove them.
- Pace the volume: hundreds of messages in seconds is bot behaviour. This is why pacing exists in serious tools; no tool on any lane can promise immunity for spam.
