What Are Bulk Messages on WhatsApp?
Bulk messages (or bulk broadcast messages) on WhatsApp mean sending a single message to multiple contacts at once—be it hundreds or even thousands of customers.
Unlike a group chat, where everyone sees each other, a bulk broadcast ensures:
Each person receives the message privately
Contact details are never shared
You can scale campaigns to thousands of recipients instantly
👉 With Whatsboost, you can safely send WhatsApp bulk broadcasts without risking your number.
Why Should Businesses Send Bulk Broadcast Messages?
Bulk messaging on WhatsApp offers several advantages over traditional communication channels:
1. Efficiency
Instead of sending 1:1 messages, you can reach thousands with one click.
2. Wide Reach
WhatsApp has 3+ billion global users, making it the most used messaging app worldwide.
3. High Engagement
On average, people open WhatsApp 25+ times per day. Open rates exceed 95%, far higher than email.
4. Cost-Effective Marketing
Even though the WhatsApp API charges per message, the ROI is higher compared to ads or cold email.
5. Personalization
WhatsApp API allows custom tags like names, orders, or dates for a one-to-one feel at scale.
WhatsApp Business App vs WhatsApp API
Before you jump into sending bulk messages, it’s crucial to understand the difference:
WhatsApp Business App
Free mobile app
Best for small businesses
Limited broadcast list size (~256 contacts)
No automation or large-scale campaigns
WhatsApp Business API
Paid API from WhatsApp
Designed for scaling communication
Allows bulk broadcast messages
