A broadcast on the WhatsApp Business Platform uses an approved message template and is sent to a list of contacts. Each recipient receives a normal one-to-one message, not a visible group.
Broadcasts power promotions, product launches, restock alerts, and seasonal campaigns. Because they are business-initiated, they require opt-in and usually fall under the marketing category for pricing.
Effective broadcasting depends on list quality and segmentation. Sending relevant messages to engaged, opted-in contacts keeps the quality rating high and avoids the blocks that come from over-messaging.
