WhatsApp Broadcast Limits Explained

How many messages you can send — and how to avoid getting your number blocked.

“How many WhatsApp messages can I actually send?” is one of the first questions businesses ask before running a campaign — usually because they are worried about getting blocked. The honest answer is: it depends on whether you use the free app or the API, and on how well you treat your recipients. Here is how the limits really work.

Limits on the free Business App

The WhatsApp Business App caps broadcast lists at 256 recipients. There is a bigger catch: a broadcast only reaches people who have saved your number in their contacts. Everyone else simply never sees it. That makes the app unsuitable for any real marketing campaign — it is meant for messaging a small set of existing, known customers.

Limits on the WhatsApp Business API

The API is built for scale, but it does not hand you unlimited sending on day one. It uses messaging tiers that grow as you prove you are a legitimate sender. A typical path:

Tier 1: 1,000 business-initiated conversations per 24 hours.
Tier 2: 10,000 per 24 hours.
Tier 3: 100,000 per 24 hours.
Tier 4: Unlimited.

You move up automatically as you send more volume while keeping a good quality rating. Note that limits are counted in conversations (24-hour windows with a contact), not individual messages — replies and follow-ups inside that window do not each count separately.

The thing that really controls your limit: quality rating

Meta assigns every API number a quality rating — Green (high), Yellow (medium), or Red(low). It is based on how recipients react over the last seven days. Lots of blocks and “report” taps drag it down. A low rating shrinks your sending limit and, if it stays low, can get the number flagged or restricted.

In other words, your real limit is not just the tier number — it is how much people want your messages. Send relevant messages to people who opted in, and you climb tiers. Spam, and you get throttled.

How to broadcast without getting blocked

1. Only message people who opted in. Buying or scraping contact lists is the fastest way to a Red rating and a ban.

2. Use approved templates correctly. Business-initiated messages must use pre-approved templates. If your templates keep getting rejected, see why WhatsApp templates get rejected.

3. Make it easy to opt out. Giving people a simple way to stop reduces blocks and reports — which protects your rating far more than squeezing out a few extra sends.

4. Segment instead of blasting everyone. Sending the right message to the right group gets better engagement and keeps your quality green.
