WhatsApp Broadcast Limit Explained

Almost every page on this topic answers "what is the WhatsApp broadcast limit" with a single number, and that is why so many businesses plan a campaign that fails. The number depends entirely on which product you are sending from, and the two products count completely different things.

The WhatsApp Business app — the free app you install on a phone — has a feature called a broadcast list. It is a saved set of recipients that receives the same message as individual chats. Its limit is a list size: 256 contacts per list.

The WhatsApp Business Platform (the API) has no broadcast lists at all. Instead it has a messaging limit, which Meta defines as the maximum number of unique WhatsApp user phone numbers your business can deliver messages to, outside of a customer service window, within a moving 24-hour period. That is not a message count and not a list size. It is a count of distinct people reached in a rolling day.

Because these are different systems, the answers to "per day" and "per month" also differ. The app's 256 is a per-list cap with no stated monthly ceiling. The Platform's tier is a rolling 24-hour recipient ceiling with no monthly ceiling either — the month only matters because it is how you happen to plan campaigns.

Source for the Platform figures throughout this page: Meta's messaging limits documentation on developers.facebook.com, checked 19 August 2026. Meta revises these pages, so re-check before you commit budget.

The broadcast list cap is 256 contacts per list, and it has a second condition that causes far more damage than the number itself: a broadcast message is only delivered to a recipient who has your number saved in their contacts.

This is why broadcast lists silently under-deliver. Nothing fails visibly. The app does not warn you. You add 256 numbers, you press send, and the message reaches only the subset of those 256 people who have previously saved your business number on their phone. For a retailer whose customers gave a number at billing but never saved it back, that subset can be a small fraction of the list — and you have no report telling you so.

Two practical consequences follow.

First, list size is rarely your real constraint. If you have 3,000 customers, you can create twelve lists and send twelve times. It is tedious, but it is not blocked. The constraint that actually costs you reach is the saved-contact rule, and adding more lists does not fix it.

Second, "get customers to save your number" becomes a real acquisition task if you intend to keep using the app. Printed QR codes at the counter, a save-our-number line in your order confirmation, a first message that gives people a reason to add you. None of this is needed on the Platform, where delivery does not depend on the recipient's address book.

If you send through the API, your ceiling is a messaging tier, and it moves.

• New business portfolios start at TIER_250 — 250 unique recipients per rolling 24 hours, outside a customer service window.
• The next step is TIER_2,000. You reach it by completing Meta's scaling requirements and then passing message-quality analysis. On approval, Meta raises the limit immediately.
• Above 2,000, scaling is automatic. Two conditions must both hold: you are sending high-quality messages across all your business phone numbers and templates, and in the last seven days you have used at least half of your current messaging limit. When both hold, your limit rises one level within six hours.

Three things about this design catch people out.

It counts recipients, not messages. Sending one customer six template messages consumes one unit of your limit for that 24 hours, not six. Sending six customers one message each consumes six.

It only counts messages sent outside a customer service window. Replies to a customer who has messaged you first do not eat into the tier. A business doing high-volume support inside open windows can operate comfortably at a low tier.

It is a moving window, not a calendar day. There is no midnight reset to plan around. Volume you sent at 3pm yesterday is still counted at 2pm today.

You will also see it claimed that the API starts at 1,000 recipients per 24 hours. Meta's current documentation says 250. Treat the 1,000 figure as stale wherever you find it.

Note the incentive built into automatic scaling: because you must use at least half your current limit in the past seven days to move up, a business that sends in occasional large bursts and then goes quiet can sit at the same tier for months while a business sending steadily every day climbs. If you plan to scale, send consistently rather than in monthly spikes.

The short version: if you are on the app, your problem is delivery, not capacity. If you are on the Platform, your problem is capacity in the first weeks and quality thereafter.

If the 256 list cap is your ceiling and delivery is unreliable, the fix is not more lists. It is moving to the WhatsApp Business Platform, where delivery does not require the recipient to have saved your number, and where you get delivery and read status per message rather than guessing.

If your messaging tier is your ceiling, work the two conditions Meta actually measures. Keep template quality high — that means relevant messages to people who expect them, because quality signals are driven by how recipients react. And send steadily enough to use at least half your limit across a seven-day period, since that is an explicit precondition for automatic scaling.

If you are not sure which system you are on: if you send by opening an app on a phone and tapping a list, you are on the Business app. If a tool sends on your behalf against an approved template and a business phone number registered with Meta, you are on the Platform.

Understanding your limit is the easy part; what happens after the send is the harder one. WhatsApp tools automate inside WhatsApp. HelloGrowthCRM continues the conversation off it — the same contact reachable on SMS, email and dialer, with tasks and stages on a sales pipeline, so a broadcast that gets a reply becomes a tracked opportunity rather than an unread chat. WhatsApp Campaigns are available on our tier 2 plans and above, and a free plan is available. See the plans, or read our guide to sending a broadcast step by step.
