Not in the way most people mean it: WhatsApp says its products aren't built for bulk or automated messaging, and both have always broken its Terms of Service. What it does allow is the WhatsApp Business app and the WhatsApp Business Platform, broadcast lists that reach up to 256 people who've saved your number, and marketing messages for customers who haven't.
What WhatsApp's own notice says
WhatsApp's help article on unauthorised bulk messaging starts by calling itself a private messaging platform, originally built for people to message friends and loved ones. Because people value talking to businesses, it built two tools to help companies manage customer conversations: the WhatsApp Business app and the WhatsApp Business Platform. Then it draws the line. Bulk and automated messaging aren't what its products are for, and WhatsApp says both have always violated its terms.
Worth knowing: that notice dates from 2019. It said that from 7 December 2019 WhatsApp would take legal action against people it decided were engaged in, or helping others with, automated or bulk messaging or non-personal use, even when that decision rested on information from outside the platform, such as a company's public claims about how it can use WhatsApp. The page is still up as of Nov 2026.
It also says it uses machine learning and the information available on the platform to find and ban accounts, and that it's stopped millions of abusive accounts that way. It admits some companies try to dodge those systems, which is why it adds legal action on top. If the ban side is what worries you, I've rounded up the triggers in why WhatsApp Business accounts get banned.
The routes WhatsApp does allow
Here's how the options line up, as of Nov 2026, from WhatsApp's own help pages:
| Route | Who receives it | Limit or catch |
|---|---|---|
| Broadcast list on personal WhatsApp | Contacts who've saved your number | Up to 256 contacts on each list; not supported on Windows, Mac or Web |
| Broadcast list on the WhatsApp Business app | Contacts who've added your business number to their phone | Same saved-number rule; it's one-to-many, so replies come back as separate chats |
| Marketing message, called a business broadcast in some countries | Customers who haven't saved your number as well | Only in some countries, and may not be available to you yet |
| Group chat | Everyone in the group, who can all see each other | It's a conversation, not a broadcast |
| A bulk tool or bot sending to a list of numbers | Whoever's on the list | WhatsApp says bulk and automated messaging break its terms |
The Business app and the Business Platform are the two tools WhatsApp names for businesses. Which of the two suits you is a bigger question than this page, and I've set them side by side in WhatsApp Business Platform vs the app.
Broadcast lists, and the saved-number catch
A broadcast list lets you message several contacts at once. Each person gets it as an individual message from you, and replies come back to you as separate chats, never to the rest of the list. WhatsApp says you can have up to 256 contacts on a list and as many lists as you like.
Here's the catch that surprises people. WhatsApp says everyone on the list must have saved your number in their address book, or they don't receive the message. So a broadcast list only works for people who already know you and chose to keep your number. That's exactly why it isn't a bulk tool, and why loading a bought list into one gets you nowhere.
WhatsApp also says people in some countries might see a monthly broadcast limit, rolling out gradually. How that works is covered in the WhatsApp Business broadcast limit, so I won't repeat it here.
Setting up a broadcast on the Business app
These are WhatsApp's steps as of Nov 2026. Menu names can shift between versions.
- Open the WhatsApp Business app and go to Chats, then the menu, then Business Broadcast. You can also get there from Tools, then Business Broadcast.
- Or start from a label: Chats, then the menu, then Lists, pick a label, then the menu again, then Send business broadcast. Handy if you've already tagged your customers.
- Pick your contacts and send. Only the ones who've added your number to their phone will receive it.
- For the people who haven't saved your number, open your most recent broadcast group and tap marketing message on the banner at the top.
- Tap Edit to change the draft and, if you'd like, add an actionable button customers can tap. Then tap Next to review it.
- Tap Send now, or Schedule to send it later.
WhatsApp says the marketing message audience is set automatically to the customers who didn't receive the broadcast, so you're not doubling up on the people who did. If what you want is a back-and-forth with everyone, WhatsApp's advice is to make a group instead, because a broadcast is one-to-many.
Reaching people who haven't saved your number
This is the sanctioned answer to the question behind most bulk searches. You don't build a bigger list; you use a marketing message. WhatsApp says marketing messages, now called business broadcasts in some countries, can reach customers who don't have your number saved. It's clear that business broadcasts are limited to some countries and might not be available to you yet.
Where you do have them, you manage them from Tools, then Business broadcasts. WhatsApp says the insights show replies and an average read rate, plus delivered, read and replied for each broadcast. Two catches it lists: editing a sent broadcast doesn't change it for people who already got it, and deleting one doesn't remove it from their phones. Some metrics are estimates and don't reflect people who've turned read receipts off. Some businesses get extra business broadcasts through a Meta Verified subscription, which WhatsApp describes as a trial that may not be available to you.

How WhatsApp spots abuse
Because messages are end-to-end encrypted, WhatsApp says it relies on information from users, from your business account and registration, and other signals to spot businesses breaking its business terms and policies. The user part is the one I'd keep front of mind. When someone blocks or reports a business or a message, WhatsApp says it receives the last five messages that business sent them, the reported user or group ID, when those messages were sent and what type they were. It may also review accounts when profile information is submitted or updated.
In plain terms, every unwanted message you send is one tap away from becoming evidence. Five messages to a stranger who reports you is exactly the record WhatsApp gets to look at.
One reassurance from the bulk notice itself: if you boost content and lots of people message you at once, WhatsApp says receiving many messages won't result in your account being banned. Ads that drive people into chats are fine. It's the sending side that's policed.
My verdict on bulk messaging
If by bulk messages you mean blasting a list of numbers, I wouldn't. WhatsApp says it breaks its terms, it sees your last five messages whenever someone reports you, and it's said since 2019 that it takes legal action over it. I'd start with a Business app broadcast list for customers who've saved your number, then add marketing messages for the ones who haven't, if they're available where you are. Skip any tool or service that promises to get around the saved-number rule, because that's the exact behaviour WhatsApp's notice is aimed at.
If you're planning WhatsApp outreach for a business, getting the permitted setup and the workflow right is the kind of messaging automation work I help teams with. I run AI training and workshops for teams, and help businesses with AI enablement and workflow automation, so the busywork runs itself and people get time back. Most of that work is with SaaS marketing teams and small businesses. Here's how we can work together.
