WhatsApp broadcast: the complete guide to bulk messaging
How broadcasts differ from groups, how to send one properly, and the practices that keep engagement high.
Written by the Blutec team
What is a WhatsApp broadcast?
A WhatsApp broadcast sends a single message to multiple contacts at once. Unlike a WhatsApp group, recipients receive the message as a private chat and cannot see the other recipients, which makes it suited to marketing campaigns, announcements and notifications.
With Ping by Blutec you can send broadcasts to 10,000+ contacts per campaign using the official WhatsApp Business API — legally, and with full analytics.
Broadcast vs group messages
| Feature | Broadcast (via API) | Group message |
|---|---|---|
| Recipient limit | 10,000+ per campaign | 1,024 members |
| Privacy | Recipients can't see each other | All members visible |
| Personalisation | Dynamic variables per recipient | Same message for all |
| Analytics | Delivery, read, click tracking | None |
| Scheduling | Schedule for future delivery | Manual only |
| Compliance | Official API, fully compliant | Risk of bans |
Group member limits are set by WhatsApp and change over time; check Meta's current documentation before planning around a specific number.
