In this guide, we will explore the most effective ways to send bulk messages on WhatsApp, ensuring high deliverability, engagement, and compliance.

Why Bulk Messaging on WhatsApp is Essential in 2025

#1. The Growing Importance of WhatsApp Marketing

WhatsApp has evolved beyond personal communication, becoming a critical tool for business marketing. 

With customers increasingly preferring direct messaging over emails and calls, bulk messaging on WhatsApp allows businesses to:

• Reach a large audience instantly
• Improve customer engagement and response rates
• Increase conversions through personalised messages
• Automate customer support and sales inquiries

#2. WhatsApp’s Policies on Bulk Messaging

While WhatsApp allows businesses to communicate with customers, it has strict policies to prevent spam. 

Bulk messaging must be done responsibly to avoid being banned. Businesses should:

• Use approved WhatsApp Business APIs or third-party tools like Chatreachmagnet
• Send messages only to users who have opted in
• Ensure message content is relevant and valuable
• Avoid excessive messaging that could be flagged as spam

Methods to Send Bulk Messages on WhatsApp in 2025

There are several ways to send bulk messages on WhatsApp. However, the right method depends on business needs, audience size, and compliance requirements.

#1. Using WhatsApp Broadcast Lists

WhatsApp’s built-in Broadcast feature allows businesses to send messages to multiple recipients at once.

How to use Broadcast Lists:

#1. Open WhatsApp and go to the “More Options” menu.

#2. Select “New Broadcast.”

#3. Choose contacts who have saved your number.

#4. Type your message and send it.

Limitations:

• Only 256 contacts per broadcast list
• Recipients must have saved your number
• Not ideal for large-scale marketing campaigns

#2. Using WhatsApp Business API

For businesses with a large audience, WhatsApp Business API provides a scalable solution for bulk messaging.

Benefits of WhatsApp Business API:

• Send messages to unlimited contacts
• Automate responses with chatbots
• Access message analytics

Challenges:

• Requires WhatsApp approval
• Involves technical setup
• Messaging costs apply

Best Practices for Sending Bulk Messages on WhatsApp

WhatsApp enforces a strict opt-in policy. Before sending bulk messages, ensure that users have agreed to receive your communications.

Generic messages receive lower engagement. Use personalisation features in Chatreachmagnet to address recipients by name and tailor messages based on their interests.
