WhatsApp is a powerhouse for businesses looking to connect with customers instantly. With 98% open rates (10x higher than emails) and 45-60% conversion rates (20x better than emails), bulk WhatsApp broadcasts let you reach thousands of users in one go, driving engagement and sales. But sending mass messages comes with risks—if done wrong, your account could get flagged or blocked. 

In this comprehensive guide, we’ll walk you through how to send WhatsApp broadcasts effectively using the WhatsApp Business App and WhatsApp Business API with WhatsBoost, ensuring compliance and maximum impact. Let’s dive into the details!

What Are WhatsApp Broadcasts?

A WhatsApp Broadcast is a feature that lets businesses send a single message to multiple recipients, landing directly in their personal WhatsApp chats. Unlike group chats, where everyone sees each other’s names and numbers, broadcasts keep things private—each recipient feels like you’re messaging them one-on-one. With the WhatsApp Business API, you can send messages to unlimited users, even if they haven’t saved your number, as long as they’ve opted in.

Examples of WhatsApp Broadcasts:

• New product launches: “Our latest collection is here! Reply to check it out.”

• Order updates: “Your order #1234 is on its way!”

• Special offers: “Get 20% off this weekend only—shop now!”

Broadcasts are perfect for announcements, promotions, or personalized updates, making them a versatile tool for businesses.

Why Use WhatsApp Broadcasts for Your Business?

Here’s why WhatsApp broadcasts are a must-have for your marketing strategy:

• Unmatched Engagement: With 98% open rates, your messages are almost guaranteed to be seen.

• High Conversions: Conversion rates of 45-60% make broadcasts ideal for driving sales.

• Personalized Outreach: Tailor messages with customer names or order details for a personal touch.

• Cost-Effective: Free to send via the WhatsApp Business App, with affordable API credits for larger campaigns.

• Scalable: Reach a handful of customers or millions, depending on your setup.

Key Insight: Broadcasts work best when you focus on value-driven content, like exclusive deals or helpful updates, to keep users engaged and avoid spam reports.

Sending Broadcasts with the WhatsApp Business App

It’s free, easy to use, and has a built-in broadcast feature. If you don’t have an account, WhatsBoost’s setup guide here (insert URL) will get you up and running in minutes.

Steps to Send a Broadcast:

1. Open the WhatsApp Business App and tap the three dots in the top-right corner.

2. Select “New Broadcast” and pick up to 256 contacts.

3. Confirm your list with the green checkmark.

4. Write your message, hit send, and monitor delivery with double blue ticks.

Pro Tip: Only users who have saved your number will receive the broadcast, so encourage customers to add you to their contacts.

Scaling Up with the WhatsApp Business API

The WhatsApp Business API is built for medium to large businesses, offering unlimited broadcasting, automation, and advanced features. It supports:

• Mass Messaging: Send to thousands or millions of users.

• Automation: Set up chatbots for 24/7 support or abandoned cart reminders.

• Multi-User Access: Allow your team to manage conversations simultaneously.

• Personalization: Use dynamic variables (e.g., names, order numbers) for tailored messages.

Since the API isn’t a standalone platform, you’ll need a provider like WhatsBoost to simplify setup and management.

• Tier 2: 10,000 users/day.

• Tier 3: 100,000 users/day.

Retargeting Strategies for Better Engagement

WhatsBoost’s retargeting feature lets you reconnect with specific audiences, like users who:

• Read your last campaign.

• Replied with a specific response.

• Received but didn’t open your message.

How to Retarget:

1. Open a previous campaign in WhatsBoost’s dashboard.

2. Select your target group (e.g., users who clicked a call-to-action).

3. Launch a new broadcast tailored to their behavior.

Example: If 500 users clicked your last offer but didn’t buy, send them a follow-up: “Missed our sale? Use code EXTRA10 for 10% off today!”

Retargeting boosts conversions by focusing on engaged users. For example, targeting users who read but didn’t respond can increase reply rates by 30%, as they’re already familiar with your brand. WhatsBoost’s analytics make it easy to identify these opportunities.
