WhatsApp broadcasts that don’t get you blocked
In short
- Only send a WhatsApp broadcast to people who agreed to receive messages from your business on WhatsApp.
- Broadcast lists in the Business app reach only contacts who saved your number, so they suit small audiences.
- Campaigns on the WhatsApp Business Platform use marketing templates approved by Meta and need a recorded opt in.
- Blocks and reports lower your number's quality rating and can restrict how much you can send.
- Segment your list, keep frequency sensible and give every message one clear reason to exist.
A WhatsApp broadcast is one message sent to many customers at once, with each person receiving it in their own private chat. To avoid getting blocked, send only to people who opted in to hear from you on WhatsApp, use the official tools rather than workarounds, and make every message worth opening. Most businesses that get blocked didn’t do anything clever. They sent too much, to the wrong people, in the wrong way.
What is a WhatsApp broadcast and how does it work?
There are two legitimate ways to send one, and they behave very differently.
Broadcast lists in the WhatsApp Business app
In the Business app you can create a broadcast list and message everyone on it. Each recipient gets a private message and can’t see who else received it. The catch: it is only delivered to people who have saved your number in their contacts. That makes broadcast lists handy for a small, warm audience, like a yoga studio’s regulars, and not much more. WhatsApp also limits how lists can be used, and those limits change from time to time.
Campaigns on the WhatsApp Business Platform
On the official platform, often called the API, you send a marketing template: a pre-written message that can include an image, the customer’s name and buttons, reviewed and approved by Meta before use. Recipients don’t need to have saved your number, but they must have opted in. Messages go out from software, so you can segment using CRM data and track deliveries, reads and button taps. Our Business app vs Business API comparison covers the wider differences.
Why do businesses get blocked on WhatsApp?
Because recipients block and report them, and Meta pays attention. Every block or report signals that a message wasn’t wanted.
The usual causes:
- Sending to bought lists, numbers copied from groups or contacts who never agreed
- Using unofficial bulk tools that automate an ordinary account, against WhatsApp’s terms
- Sending too often, without a real reason
- Generic messages that have nothing to do with the person receiving them
- No clear way to opt out, so blocking is the only option left
What happens next? On the Business Platform, every number has a quality rating. When it falls, Meta can limit how many people you can reach, pause the template that caused the problem and, in serious cases, restrict the number. In the regular apps, behaviour that looks like mass messaging can get an account banned. Losing the number your customers know is a much bigger problem than one bad campaign.
How do you collect opt in for a WhatsApp broadcast?
Ask for it explicitly, at a moment when the customer is already engaged, and tell them exactly what they’ll get. WhatsApp’s policy requires the opt in to make clear that the person is agreeing to receive messages from your business, by name, on WhatsApp.
Good places to ask:
- An unticked checkbox on your website form or at checkout
- The end of a helpful chat: “Would you like a WhatsApp message when new stock arrives?”
- A QR code in store that opens a chat with a word like “Join”
- When someone books an appointment or completes a purchase
Sample wording for a form: “Yes, send me offers and updates from [business name] on WhatsApp. I can stop at any time.”
Record the date, the source and the wording each person saw in your CRM. Beyond WhatsApp’s own rules, many countries have privacy and marketing laws that expect prior consent for promotional messages, so clean records protect you twice.
How do you write a broadcast people don’t block?
Before writing, answer one question: why would this particular person care? If you can’t answer it, don’t send.
- Short. A few lines, one idea.
- Personal. Their name, and a reference to what they bought or asked about.
- Clearly useful. A genuine offer, a product back in stock, a freed up slot, a tip they can use.
- One action. A single button such as “Order now” or “Book a slot”.
- An easy exit. A “Stop promotions” button or a simple instruction. Leaving should be easier than blocking.
An example from a bakery:
“Hi Sam, the rye sourdough you ordered last month is back on Saturdays. Shall we set one aside for you?”
With two buttons underneath: “Yes please” and “Stop promotions”.
What should you do when someone opts out?
Honour it immediately, everywhere. A customer who tapped “Stop promotions” and then receives another promotion will block you, and fairly so.
In practice, the opt out should update your CRM automatically, so the person leaves every future campaign, not just the current list. Remember that opting out of marketing isn’t opting out of everything: a customer with an open order or a booked appointment can still receive confirmations and updates about it, as long as they contain no promotional content.
How often should you send, and when?
There’s no magic number. The right frequency is the one at which each message still feels like a service. A shop with genuine weekly deals can send more often than a business with nothing new to say.
Send at reasonable local hours, respect the weekends and holidays your audience observes, and check opt outs after every campaign. A rise means slow down. Bear in mind that WhatsApp may limit how many marketing messages a person receives from businesses overall, so even a well run campaign won’t always reach everyone.
How do you segment a WhatsApp list?
Group people by what you know about them, and write a different message for each group. One list for everyone is the fastest route to blocks.
Simple segments that work: recent buyers versus customers who haven’t been back for a while, product or service interest, location, and leads who haven’t bought yet versus existing customers. Our guide to customer segmentation shows how to build these from your CRM.
7 steps to a safe WhatsApp broadcast campaign
- Check consent. Only contacts with a recorded opt in go into the campaign.
- Pick one segment. A group with something clearly in common.
- Write the template. Short, personal, with one action button and an opt out button. Our guide to WhatsApp message templates explains what tends to get approved.
- Submit it in the right category. A promotional message submitted as a utility update may be recategorised.
- Prepare for replies. People will answer. A bot should handle common questions about the offer and pass everything else to a person.
- Send in stages. Start with a small slice of the list, watch the reaction, then widen.
- Measure. Reads, taps and sales, and above all opt outs and blocks.
Example: a gym filling quiet classes
A neighbourhood gym collects opt in when members join. On Monday it sees spare places in Wednesday’s early spin class. Rather than messaging everyone, it sends a template only to members who have booked early classes before: “There’s space in Wednesday’s early spin class. Want a spot?”, with a button to book.
Members who tap are confirmed by the bot straight into the booking system. Anyone who taps “Stop promotions” is removed from future campaigns automatically.
Pre-send checklist
- Every recipient has a recorded opt in
- The message targets one segment, not everyone
- It offers clear value and one action
- There’s an easy way to opt out
- The timing suits the recipient’s time zone
- Someone, or a bot, is ready to handle replies
The bottom line
A WhatsApp broadcast is powerful precisely because it’s personal, and that’s also what makes it sensitive: an unwanted message feels like an intrusion into a private space. With consent, segmentation and a message worth reading, it works. At Kaede Digital we run campaigns on the official platform as part of our WhatsApp bot for business service: opt in collection, CRM segments, templates and a bot that handles the replies that follow.
FAQ
Can I broadcast to everyone in my phone contacts?
It’s a bad idea. Having someone’s number doesn’t mean they agreed to receive marketing from you on WhatsApp. Sending anyway leads to blocks and reports and puts your account at risk.
What’s the difference between a broadcast list, a group and a channel?
On a broadcast list, each person receives a private message and can reply only to you. In a group, members can see each other, including phone numbers, which rarely suits marketing. A WhatsApp Channel is a one way feed people choose to follow, with no private conversation.
What should I do if my quality rating drops?
Pause marketing sends, find the message that triggered the blocks and fix it: narrow the audience, improve the content and add an easy opt out. Quality can recover as later messages get a better response.
Do I need the Business Platform to send a WhatsApp broadcast?
Not necessarily. For a small audience that knows you and has saved your number, broadcast lists in the Business app can be enough. Once your list grows, or you want CRM segments, measurement and a bot to handle replies, the Business Platform is the right tool.
