What is the WhatsApp broadcast message limit?

On the app a broadcast list holds 256 contacts and reaches only people who saved your number; on the API the limit is business-initiated conversations per 24 hours — 250 before verification, then 1,000, 10,000, 100,000 and unlimited.

The short answer

On the app a broadcast list holds 256 contacts and reaches only people who saved your number; on the API the limit is business-initiated conversations per 24 hours — 250 before verification, then 1,000, 10,000, 100,000 and unlimited.

On the WhatsApp Business app a broadcast list holds up to 256 contacts, and a broadcast is delivered only to people who have saved your number; there is no published daily total, but bursts to strangers get the number banned. On the WhatsApp Business API the limit is explicit: 250 business-initiated conversations in a rolling 24 hours before business verification, then 1,000, 10,000, 100,000 and unlimited as the number sends at volume with a healthy quality rating.

Replies to customers who wrote to you are not limited on either. A campaign tool on the API holds the remainder of an audience when the limit is hit and sends when it lifts.

Messaging limit is the term; broadcast without getting blocked is the practice.
