Broadcast List vs Group vs Campaign

Ask five Indian business owners how they message their customer base on WhatsApp and you will get three mechanisms described with one word. They behave completely differently, and picking the wrong one is not a preference error — it changes who can see your customer list, who can talk to whom, and whether your message arrives at all.

A broadcast list is a feature of the WhatsApp Business app, the free application you install on a phone. You add contacts to a saved list and send to it. Each recipient receives the message in their ordinary one-to-one chat with you. They do not know a list exists, do not see who else received it, and cannot see each other's replies. Any reply comes back to you privately.

A group is a shared room. Every participant sees the participant list, sees every message posted, and sees every reply. A group is a place, not a send mechanism.

A campaign on the WhatsApp Business Platform — the API — is a different product altogether. There are no broadcast lists on the Platform. You send an approved message template from a registered business phone number to a set of recipients, each of whom receives it as a private chat, with per-message delivery status returned to your system.

This is the table worth screenshotting, because the visibility differences are where the real business risk sits.

Two rows deserve expanding.

Groups expose your customer list to your customers. In a group of buyers, every member can read every other member's display name and number, start a private chat with them, and post to the whole room. For a distributor, that means your dealers can see each other. For a clinic or a school, it can mean disclosing who your patients or parents are to one another. There is no setting that undoes that; it is what a group is.

Broadcast lists hide replies but not delivery problems. A broadcast message is only delivered to a recipient who has your number saved in their contacts. Nothing warns you when that fails, so a list of 200 can quietly reach a fraction of that.

Scale is not only about how many recipients a mechanism accepts. It is about what breaks first as the number grows.

A group breaks socially. One unhappy customer complains in front of the others. One dealer posts a price. One person adds a number that should not be there. Moderation cost rises faster than membership, and none of it is recoverable — the messages are already read.

A broadcast list breaks silently. Adding more lists is easy, so people assume the mechanism scales. What does not scale is delivery you cannot see. You have no per-recipient status, so you cannot tell a bad list from a bad message. The ceiling on a single list is a fixed contact count, and there are separate, unrelated ceilings on the Platform — we treat both properly on our page about how many people you can actually reach on WhatsApp.

A campaign scales, with conditions. The Platform gives you delivery status per recipient and does not depend on the customer having saved your number. In exchange, business-initiated messages outside an open customer service window must use a pre-approved template, and the category Meta applies to that template at the time of use determines what you pay. Marketing templates are always charged. Utility and authentication templates are free inside an open customer service window and charged outside it.

Use a group when the members are meant to meet. A group is right when the value is the room: a cohort of students, an internal team, a set of channel partners you intend to introduce to each other. If members meeting each other would be a problem, a group is the wrong instrument regardless of convenience.

Use a broadcast list only for a small, familiar audience. If you have a few dozen regulars who have your number saved and you are sending occasionally from a phone, a broadcast list is fine and free. Beyond that, you are sending into a reporting vacuum.

Move to a campaign when you need proof of delivery. The trigger is not volume alone. It is the first time someone asks "did they get it?" and you cannot answer. Delivery reporting, multiple agents on one number and template-based sending all live on the Platform.

All three mechanisms are one-way pushes. What separates a campaign from an announcement is what happens to the replies, and to the silence.

Replies to a campaign land in a shared inbox rather than one person's phone, which is the point of using a business number at all. But the more common outcome is no reply. When a customer does not respond, the 24-hour customer service window either never opens or closes, and from that point every message you send them is a template send. WhatsApp tools automate inside WhatsApp, so this is where a WhatsApp-only tool stops having anything to do.

Decide the mechanism by the question you will be asked afterwards. If it is "who else is in here", you want a group. If it is "did it reach them", you want a campaign, and a group or broadcast list will not answer it.
