WhatsApp broadcast: how it works, the difference from groups, and the real limits

Want to send the same message to fifty customers without creating yet another group? The feature you’re looking for is the broadcast list: it has been part of WhatsApp for years and it’s free. It does come with rules and limits that aren’t very intuitive — the most famous being that the message only reaches people who have saved your number in their contacts. Let’s look at how it works, when to use it, and when you need something more.

What a WhatsApp broadcast list is

A broadcast list is a list of contacts you send the same message to all at once. The key difference from a group: each recipient receives the message in a normal private chat with you, as if you had written to them personally. They don’t see the other recipients, they don’t know they’re on a list, and if they reply, the reply comes only to you.

For the recipient, then, the experience is identical to an individual message. For the sender, it’s a huge time-saver — as long as you stay within the app’s limits, which we’ll cover shortly.

Broadcast vs groups: the differences that matter

Broadcasts and groups look similar, but they serve opposite purposes. The table sums up the practical differences:

The practical rule: if the recipients shouldn’t be talking to each other, the group is the wrong tool. Putting customers in a group exposes their numbers to strangers (a privacy problem, too), turns every reply into noise for everyone, and makes the communication feel like collective spam.

How to create a broadcast list in 4 steps

• 1. Open WhatsApp and go to “New broadcast”: on Android from the three-dot menu, on iPhone from the “Broadcast Lists” entry above the chat list.
• 2. Select the contacts to include (up to 256) and confirm: the list appears among your chats, like a special conversation.
• 3. Write the message and send it: it will go out as an individual message to every contact on the list — text, photo, or document.
• 4. Reuse the list for future sends: the recipients stay saved, and you can add or remove them from the list’s info.

The limits of the free app (that you only discover later)

• Delivery only to people who have you in their contacts: if the customer never saved your number, the broadcast simply doesn’t reach them — and you don’t even notice.
• Maximum 256 contacts per list: beyond that, you have to create and maintain several parallel lists by hand.
• No statistics: no counts of deliveries, reads, or replies; to know how it went you’d have to open the chats one by one.
• No scheduling: sending is manual, here and now. No campaigns prepared in advance.
• No segmentation: no filters by interest, city, or purchase history; the list is static and must be curated by hand.
• One phone, one operator: the number lives on the device and the team can’t work on the conversations in parallel.
• Risk of being blocked at high volumes: massive, repeated sends to contacts who don’t engage can trigger WhatsApp’s anti-spam protections.

When a broadcast isn’t enough: the alternatives

WhatsApp Business (free app)

The WhatsApp Business app adds a business profile, labels, quick replies, and automated greeting and away messages. Broadcast lists, however, work exactly as in the regular app, with the same limits on contacts, volume, and statistics.

Professional platforms

When contacts grow into the hundreds, the leap is to a platform: you send to segmented lists without the contacts-saved constraint (with Meta-approved templates on the official API), scheduling, delivery and read statistics, multiple operators on the same number, and automations like chatbots and reminders.

SendApp covers both paths: Cloud connects the WhatsApp number you already use via QR, while Official works on Meta’s official API with templates and verification. In both cases you get segmented campaigns with statistics and zero markups on messages, from €19 a month with a free trial.

When to use what: three scenarios

• A shop with a few dozen loyal customers who are already in each other’s contacts: the app’s broadcast list is more than enough for the monthly update.
• A community that needs to interact (a course, a team, a building’s residents): you need the group, because the whole point is the conversation between members.
• A business with hundreds of contacts, regular campaigns, and several people answering: you need a platform, because manual contact lists and hand-sent messages stop holding up.

Best practices for multiple sends

• Ask for consent before adding someone to a list: besides being required for promotional messages, it reduces blocks and reports.
• Get yourself saved to their contacts at the first interaction: a simple “save our number to receive our offers” unlocks delivery of future broadcasts.
• Write as if it were a personal message: the advantage of a broadcast is precisely that it feels one-to-one; flyer-style copy wastes it.
• Segment by hand, too: three small, relevant lists beat one generic catch-all list.
• Keep the frequency in check: one well-crafted message a month is worth more than a weekly one that gets ignored.
