WhatsApp broadcast messages that reach the right people

A sale, a launch, an event reminder. A WhatsApp broadcast gets read almost straight away, but only if it arrives. Here is how broadcasts work in the app, how they work at business scale, and how AssistantLabs sends each audience its own message and answers everyone who replies.

WhatsApp broadcast lists: what they do and where they stop

The WhatsApp Business app has broadcast lists. You pick contacts, write one message, and each person receives it as a private chat from you without seeing who else got it. Anyone who replies, replies only to you. For a small business with a few dozen regulars, that is a good, simple tool.

It has limits, though. A broadcast only reaches people who have saved your number in their contacts, so part of the list never sees it and you cannot tell who. Each list has a cap on how many people it can hold, you build lists by hand on one phone, and there is no way to segment by what you know about your customers.

Businesses that send at scale move to Meta’s official WhatsApp Business API. There you send template messages that Meta has approved in advance, only to people who agreed to hear from you, and Meta bills each message that is delivered. You reach the whole audience, including people who never saved your number, and you see what happened to every message.

What AssistantLabs adds to WhatsApp broadcasts

Audiences from your CRM

Send to your VIPs, to everyone who found you on Instagram, or to people who have not bought in two months. A dynamic audience updates itself as customer details change.

Personal, not bulk

The customer’s name and details from their record go into the message. Each person gets a message written to them, not another bulk blast.

Every reply answered

A reply to your broadcast lands in that customer’s existing conversation, and your personal assistant takes it from there: answers questions, sends a link, books the appointment.

Opt-outs respected automatically

Anyone who asked to stop receiving marketing is never in an audience. You do not have to clean lists by hand.

Now or scheduled

Write it once and send now, or schedule it for the hour your customers actually read.

Results for every send

How many people it went to, how many were sent, how many failed and when. The replies are waiting in the conversations, with the assistant’s answers.

An expert connects WhatsApp with you in one session. After that, each send takes a few minutes.

  2. 2

    Write the message

    Choose an approved template, or write a new one and submit it to Meta. Add the customer’s name, an image and a button with a link.

  3. 3

    Send, and let the assistant answer

    Send now or schedule it. Replies land in the conversations, the assistant answers, and you see the results of the send.

WhatsApp bulk messages for business, in practice

Online stores

An end-of-season sale to everyone who bought in the last year, with an image and a link. Anyone asking about a size gets an answer from the assistant in the chat.

Clinics and service providers

A note to clients who have not visited in six months. Anyone who replies picks a free slot from your calendar in the same conversation.

Events and workshops

An invitation to last event’s attendees, and a reminder the day before to everyone who signed up.

Restaurants and local businesses

A holiday menu or a special night for your regulars, with a table booked straight from the reply.

Broadcast list in the app vs sending through the API

Both are "WhatsApp broadcasts", but they are built for very different scales.

FAQ

WhatsApp broadcast FAQ

A sale, a launch, an event reminder. A WhatsApp broadcast gets read almost straight away, but only if it arrives. Here is how broadcasts work in the app, how they work at business scale, and how AssistantLabs sends each audience its own message and answers everyone who replies.

Talk to us on WhatsApp
How do I send a WhatsApp broadcast message?
In the WhatsApp Business app, create a broadcast list, pick contacts and send; it only reaches people who saved your number. At business scale you send through the official WhatsApp Business API: pick an audience, write the message on a template Meta has approved, and send now or schedule it.
How many contacts can a WhatsApp broadcast list have?
In the app, each broadcast list is capped and meant for small lists, and the message only reaches people who saved your number. Through the API there is no such list: you send to audiences from your CRM, made up of people who agreed to hear from you.
Is there a WhatsApp broadcast limit per day?
Yes. On the API, Meta sets a daily limit on how many different people one number can contact with template messages, and raises it over time for numbers whose messages people do not block or report. Sending only to people who opted in, with content that matters to them, is what grows that limit.
WhatsApp broadcast vs group: what is the difference?
In a group everyone sees everyone: the numbers, the messages and the replies. In a broadcast each person gets the message in a private chat, and replies come only to you. For updates to customers, a broadcast is almost always the right choice.
Why did my broadcast not reach some people?
Almost always because they have not saved your business number in their contacts; that is how broadcast lists in the app work. Template messages sent through the API reach people who never saved your number, as long as they agreed to hear from you.
How much do WhatsApp bulk messages cost?
Meta bills each delivered message. The rate depends on the recipient’s country and the message category, and marketing messages are the more expensive category. Messages your customers send are never billed, and since 1 October 2026 your replies inside the 24-hour window are billed too. The full breakdown is on our WhatsApp API pricing page.
Do customers need to opt in to WhatsApp broadcasts?
Yes. Meta requires that you only message people who agreed to receive WhatsApp messages from you, and the messages must be built on a template Meta approved in advance. Anyone who asks to stop receiving marketing is kept out of your audiences.
