WhatsApp publishes exactly one number for broadcasts: 256 recipients per list. Everything else people call a "broadcast limit" is either a delivery rule most senders have never read, or a behavioural limit WhatsApp enforces without publishing a figure. That gap is why "broadcast not delivered" is searched thousands of times a month.
This guide separates the three: the hard list limit, the silent delivery rule that drops most of a list, and the behavioural limits that turn a heavy broadcaster into a banned number. The how-to for creating and sending a list lives in the broadcast guide. This page is about limits and delivery only.
The list limit: 256 recipients, as many lists as you like
A broadcast list holds up to 256 recipients, in both WhatsApp and the WhatsApp Business app. You can create multiple lists, and a contact can be on several. No setting, plan or verification raises 256; it is the same for a personal account, a Business app account and a Meta Verified one.
A list send delivers a separate private message to each recipient. Recipients do not see each other, and replies come back as ordinary one-to-one chats. That also means a list of 256 is 256 outgoing messages the moment you tap send, and WhatsApp’s systems see them that way.
Lists are created and managed on the phone, and only people saved in your phone’s contacts can be added to one. WhatsApp Web and linked desktop devices can carry on the conversations that replies open, but the list itself lives in the mobile app.
The delivery rule: only people who saved your number get it
This is the limit that actually breaks broadcasts, and WhatsApp states it plainly on its responsible-use page: "Messages sent using a broadcast list will only be received when users have added your phone number to their contact list."
The failure is silent on both sides. You see the message go out. The recipient who never saved you sees nothing, and you get no error and no list of who was skipped. A list built from order forms, event sign-ups or a spreadsheet export is usually mostly unsaved, which is how a 200-name broadcast reaches a few dozen people and the owner never finds out.
The fix is a habit, not a setting: ask people to save your number before you need to broadcast to them. A QR code on the counter or a wa.me link makes that one tap, and a customer who saved you and messaged you first is also the customer WhatsApp says you should be messaging. Its first rule for responsible use is to "give contacts your phone number so they can message you first."
The warning WhatsApp puts right next to the delivery rule
The same Help Center entry continues: "Please keep in mind, frequent use of broadcast messages may lead people to report your messages, and we ban accounts that are reported multiple times." It sits under the heading "Over-using broadcast lists", in a list of practices that "may cause your account to be banned".
Read that the way WhatsApp means it. Broadcast lists are allowed. Using them often, to people who did not ask for offers, is a named ban cause. WhatsApp does not say how often is too often and does not publish a report threshold; it says "multiple times". A daily promotion to the same 256 people is the pattern most likely to get there. People who manage large numbers of business WhatsApp numbers add a cheap fix: end each broadcast with a "write stop" line, because writing stop is easier for an annoyed recipient than tapping Report, and it is the reply that keeps the number.
The white paper behind the policy is blunter: "Our service is not a broadcast platform." WhatsApp says roughly 90% of its messages go from one person to another, and its detection is tuned to that shape of traffic. A broadcast list is a tolerated exception, not a marketing channel.
How broadcasts feed the spam score
WhatsApp bans on behaviour and feedback, not on content it cannot read. Its white paper names machine learning "features" such as "number of reports, rate of messaging, reputation of other users sharing the same computer network". A broadcast moves several of them at once.
- Velocity. Up to 256 individual messages leave the number in seconds. WhatsApp says normal users operate "relatively slowly", "tapping messages one at a time", and that the intensity of activity "can provide a signal that accounts are abusing WhatsApp". A list send is the opposite of one at a time.
- Identical content. Every recipient gets the same text, image or document. Repeated and forwarded content is what WhatsApp built forward labels and forward limits to discourage, and identical copies to many chats is how a script looks. Industry estimates from people who manage many business numbers put the flag point at about 15 near-identical messages an hour, a community-tested estimate rather than a WhatsApp rule, which makes it the real limit behind the 256 figure: a full list sent at once is 256 identical messages in one minute.
- Reports, weighted by relationship. A broadcast only reaches people who saved you, so the extra weight WhatsApp gives a report on "the first message they receive from an unknown number" does not apply. But a recipient who saved you for one delivery update and now gets weekly offers still has a report button, and WhatsApp bans accounts "reported multiple times".
- One-way traffic. If 256 messages go out and a handful of replies come back, the number looks like a broadcaster, not a conversation. Answering replies is part of keeping the account looking like what WhatsApp expects.
None of these is a published threshold. They are the features WhatsApp says its systems weigh, and it says over 75% of bans happen without any recent user report. A broadcasting habit that felt fine for months can end in a ban after one busy week, and nobody had to complain first.
List limit vs behavioural limits: there is no daily cap
People search for a daily message limit because they want a number to stay under. There is none. WhatsApp does not publish a per-day message cap for personal accounts or the Business app; the only published broadcast figure is 256 per list. What exists instead is a set of behavioural limits, velocity, unsaved recipients, identical content, blocks and reports, and network reputation, scored by systems WhatsApp says run "24 hours a day, 7 days a week".
That is worse news than a cap, because a cap can be worked around and a behaviour cannot. Ten lists of 256 sent back to back is 2,560 messages in minutes from one phone, WhatsApp’s "100 messages in 15 seconds" example scaled up, and it does not matter that each list was within its limit. The limit you were inside was never the one that counts.
Two industry observations sharpen this. People who manage large numbers of business WhatsApp numbers report that how many different people a number reaches in a short time matters more than how many messages it sends, and a 2026 guide from the same world adds that 500 messages into conversations you already have are judged very differently from 500 messages to people you have never messaged, because WhatsApp already knows who you talk to. Both are community-tested estimates, not WhatsApp rules, but they explain the pattern: a list of people who saved you but never chatted with you is, to WhatsApp, a burst of first contacts.
The escalation is worth knowing. A temporary ban shows a countdown and escalates on repeat. A permanent ban shows "This phone number can’t use WhatsApp" with a Request review button, and WhatsApp says most reviews complete within 24 hours; if the button is missing, the ban is final. There is no warning screen between fine and banned on the app.
What the WhatsApp Business app adds, and what it does not
The Business app has the same broadcast lists with the same 256 limit and the same save-me rule. On top it adds a business profile, labels to organise contacts (which makes building a list per segment easier), quick replies, and, if you pay for it, Meta Verified.
What it does not add is any broadcast allowance. It is judged by the same behavioural systems as a personal number, and a ban on the Business app looks identical to a ban on the personal app. WhatsApp adds that a banned account "automatically loses its Meta Verified subscription", with no refund if the ban was for spam or a policy violation. The checkmark does not raise a limit or soften a ban.
The Business Messaging Policy also sets the consent rule: a business may only contact someone who gave it their number and "agreed to be contacted by the business over WhatsApp", and "spamming, or surprising people with business communications" is a named violation. Saving your number is not that agreement, but it is the closest thing a broadcast list has, which is one more reason to broadcast only to people who chose to save you.

What to do when you outgrow lists
A business hits the edge of broadcast lists in one of three ways: the list is full, most of it is unsaved and undelivered, or the frequency needed to sell is the frequency WhatsApp warns about. Each has a different answer.
- Full list: more lists, segmented by what people actually want. A list per product line or per city gets fewer reports than one list for everyone, and each stays under the limit on its own. Do not send them all back to back; that recreates the velocity problem.
- Unsaved and undelivered: stop broadcasting to people who did not save you, and get them to message you first. A QR code, a link on the website, an offer that starts inside a chat. WhatsApp says that "receiving many messages at once will not result in an account ban", so inbound volume is the one kind of volume that is never a problem.
- Frequency: cut it, or move promotional traffic to something that paces it. The WhatsApp Business Platform, the API, is the high-volume lane: a separate number, pre-approved templates, per-message pricing and a quality tier that limits sending when it drops. Linked-device tools such as Spun stay on your existing number and send individual messages to lists you define, without the 256 cap or the save-me requirement, with a random gap between messages, a server cap on the pace, quiet hours, saved-contacts and recent-activity filters, and opt-out words in 11 languages applying a label every campaign respects.
Whatever you move to, the Help Center warning travels with you. A tool can slow the send and keep it to people who know you, which reduces the risk on the signals WhatsApp scores. It cannot make a weekly offer welcome to someone who only wanted a delivery update. No lane is immune.

The problems behind broadcast lists, and how Spun handles each one
- 1
Half the list had never saved your number
A broadcast list silently skips anyone who has not saved you, so the message reaches a fraction of the list and you never learn which. Spun campaigns send individual messages to lists you define, so the save-me rule does not apply, and the "Saved contacts only" and activity filters keep them to people who know you; strangers are still a signal WhatsApp scores, so the consent half is yours.
- 2
You hit 256 and started a second, third and fourth list
Several lists sent back to back is thousands of identical messages in minutes from one phone, the burst WhatsApp’s velocity scoring reads whatever the per-list cap. Spun builds audiences from labels and segments with no 256 cap and sends one message at a time on a pace preset with random gaps, under a server cap of 8 a minute by default and outside quiet hours; slower reduces the risk, it does not promise immunity.

You broadcast every week because it is the only way you stay in touch
Frequent broadcasts are the named ban cause, and a number that only broadcasts looks like a broadcaster, not a conversation. Keep In Touch in Spun lists the contacts you have not spoken with in 7, 30 or 90 days per label, with a quick-send box, so staying in touch becomes individual messages, and a warning fires before a campaign overlaps the last 7 days of sends.
