WhatsApp offers several ways to send messages in bulk.
Here’s the quick summary:
WhatsApp Business App Broadcasts let you send free messages to up to 256 contacts—only if they’ve saved your number.
WhatsApp Web works similarly but makes typing and formatting easier.
WhatsApp Business API is built for high-volume messaging, automation, scheduling, and analytics.
Message limits depend on your quality rating—new accounts start with 1,000 daily messages and automatically scale up with good engagement.
Always follow compliance standards: clear opt-ins, easy opt-outs, and no spam.
Free methods work for small teams. Growing businesses need the API for templates, segmentation, automation, and reliable scaling.
When you launch a new offer or announcement, sending messages one by one is unrealistic—especially for growing businesses.
Bulk messaging solves this by letting you reach hundreds (or thousands) of customers instantly, while keeping each conversation private and personalized.
This guide breaks down everything you need to know:
types of bulk messages, free vs paid methods, limits, compliance rules, and step-by-step instructions.
You can send bulk WhatsApp messages in three ways:
1. Broadcast Lists (Free – WhatsApp Business App)
Send messages to up to 256 saved contacts at once.
2. WhatsApp Business API (Paid)
Send messages to thousands with automation, scheduling, template approval, and analytics.
3. Third-party Platforms (e.g., Wati)
Access the official API with an easy dashboard for templates, segmentation, and performance tracking.
Free broadcasts are great when you’re just starting, but once you need scale and automation, platforms like Wati become essential.
Bulk WhatsApp messages let you send the same message to multiple people simultaneously—but each receives it as a private chat.
Customers reply individually, and their responses appear in separate conversations. This keeps communication personal and organized while scaling reach.
If you're a small business, the WhatsApp Business App gives you a simple free option.
Method 1: Broadcast Lists on WhatsApp Business App
Steps:
Open WhatsApp Business App
Tap Menu (three dots)

Send
Only customers who have saved your number and opted in will receive the message.
Method 2: WhatsApp Web
Same limits apply but typing is easier:

Limitations of Free Broadcasts

If you’ve outgrown these limits, the WhatsApp Business API is your next step.
