WhatsApp Broadcast List vs Group vs Community vs API Campaign: Which Should You Use?

Ask five shop owners how they send an offer to customers on WhatsApp and you will get five answers: a broadcast list, a group, a community, a forwarded message, or a campaign tool. They all look similar from the outside, but they behave very differently. Pick the wrong one and your message reaches half your customers, exposes everyone's phone numbers, or puts your number at risk.

This guide compares the four main options side by side, shows what each is good for, and gives you a simple way to choose.

The Four Options at a Glance

Broadcast list: a one-to-many message from the WhatsApp or WhatsApp Business app. Each person receives it as a private message.

Group: a shared chat where every member can see and reply to everyone else.

Community: a collection of related groups under one umbrella, with announcements from admins.

API campaign: a template message sent from the WhatsApp Business API through a platform such as VedLink AI, with delivery tracking.

Broadcast Lists: Simple but Limited

A broadcast list lets you write one message and send it to many contacts. Replies come back to you privately, so customers cannot see each other. That makes it feel like a personal message, which is why small shops like it.

The catches are important:

Only saved contacts receive it. At the time of writing, a person gets your broadcast only if they have saved your business number in their phone. Customers who never saved you will not see it, and you will not be told.

There is a size cap. A list can hold a limited number of recipients (WhatsApp has set this at 256 contacts per list). Check the current limit in WhatsApp's help centre.

Little feedback. You do not get proper delivery, read or click reporting, and there is no personalisation beyond what you type.

Manual work. You build and update each list by hand.

Broadcast lists suit a small business with a few hundred regular customers and an occasional message. They become awkward once you have thousands of contacts or need to know what worked.

Groups: Good for Conversation, Poor for Promotion

A group is built for discussion. Everyone sees everyone's messages and phone numbers. WhatsApp sets a limit on group size, which you should check in its help pages.

Groups work well for a coaching class sharing a timetable with parents, or a small team coordinating. They work badly for promotions to customers:

Privacy: members can see each other's numbers, which many customers dislike.

Noise: one chatty member can bury your offer, and people mute or leave.

Consent: adding customers to a group without asking invites complaints and blocks.

If you want a space for announcements without the chatter, look at communities, covered in our guide to creating a WhatsApp community.

Communities: Announcements Across Related Groups

A community links several groups, such as different batches in a coaching class or different branches of a store, and lets admins send an announcement to all of them. It gives structure, but it is still a group-style product. Members join voluntarily, you see little data about reach, and it is not meant for one-to-one sales follow-up.

API Campaigns: Built for Scale and Tracking

A campaign on the WhatsApp Business API sends a pre-approved template to opted-in customers, from your business number, each one as a separate private message. Because it runs through software, you get things the other options cannot offer:

Personalisation: insert the customer's name, order or appointment details into the message.

Segments: send only to the right audience, using tags and lists. See contact segmentation.

Reporting: see sent, delivered, read and failed counts for each campaign.

Scale: reach people beyond the small caps of the app, subject to your account's messaging limit.

Replies in a team inbox: responses land in a shared inbox where staff can answer, not on one person's phone.

The trade-offs are that you need API access, templates need Meta's approval, and marketing messages carry a per-message charge set by Meta. We do not quote rates here because they change; see WhatsApp Business API pricing in 2026 or use our cost calculator. Our bulk campaigns feature explains how sending works inside VedLink AI.

Rules That Apply to Every Option

Whichever route you choose, a few things do not change.

Get permission first. Message people who have agreed to hear from you. Our guide on opt-in and data privacy explains how to collect and record it.

Make opting out easy. Tell people how to stop receiving offers. Ignoring this leads to blocks and reports.

Watch your quality. On the API, blocks and reports lower your quality rating, which can reduce your messaging limit. Read quality rating and messaging limits.

Do not use unofficial bulk tools. Software that automates the regular app against WhatsApp's terms can get your number banned. See how to send bulk WhatsApp without getting banned.

Which One Should You Use?

You have under a couple of hundred regular customers and send an occasional note: a broadcast list is enough. Ask customers to save your number first.

You need to coordinate a fixed set of people who should talk to each other: use a group, such as a class batch or a staff team.

You run several groups and want one announcement channel: consider a community.

You send offers, reminders or order updates regularly, or want to know what worked: use API campaigns.

Example: A Neighbourhood Grocery Store

A grocery store starts by sending a weekly fresh-stock message to a broadcast list of about 150 regular customers. It works until the list is full and customers who never saved the number complain that they missed offers. The owner then moves to API campaigns: customers opt in at the billing counter through a QR code, the owner tags them by locality, and each locality gets a message about its own delivery slot. Replies arrive in one inbox. The details here are an illustration, not a promised outcome.

Frequently Asked Questions

Can I send a broadcast without customers saving my number? On a broadcast list, no. With API template messages, yes, provided the customer has opted in and your template is approved.

Is a group better than a broadcast for offers? Usually not. Group members see each other's numbers and can reply publicly, which many customers dislike.

Do I need the API for just 200 customers? Not necessarily. But if you want tracking, personalisation or a team to handle replies, the API is the better tool even at that size.

How do customers join my list in the first place? A link or QR code is the simplest route. Our click-to-chat link and QR guide shows how to create one.

Final Thoughts

The right choice depends on how many people you reach, how much you need to measure, and how much privacy your customers expect. Start with the smallest tool that does the job, and move to API campaigns as soon as manual lists start costing you reach or time.
