WhatsApp has become one of the most effective ways for businesses to reach out, share updates, and build lasting connections with their audience. As the platform grows, a range of new features is emerging to help businesses save time, boost engagement, and add a personal touch to every campaign.

In this blog, we will walk you through how to broadcast messages on WhatsApp the right way, along with key dos and don’ts to keep your campaigns efficient, compliant, and engaging.

Understanding WhatsApp Broadcasts

WhatsApp Broadcast is a feature that allows businesses to share information, offers, or updates with many recipients at once on WhatsApp. Each message is delivered individually, and replies appear in separate chats that the business can manage in a single inbox.

Why Use WhatsApp Broadcasts?

WhatsApp broadcasts offer a direct, personal, and effective way to reach your customers. Businesses across industries rely on them to build rapport and increase engagement.

Instant Communication

WhatsApp broadcasts ensure that your messages are delivered straight to your customers’ inboxes within seconds. Whether you are sharing offer announcements or reminders, broadcasts help you communicate important information quickly. Unlike emails that often go unread, WhatsApp notifications are hard to miss and are typically seen immediately.

High Open and Response Rates

Messages sent through WhatsApp broadcasts have much higher open rates than emails or SMS. People check WhatsApp several times a day, so your messages are almost always seen. The conversational nature of WhatsApp creates real-time interactions that feel natural and personal.

Personalisation

You can personalise these messages with details such as a customer’s name or city to make them feel unique. Personalised broadcasts show that your business values its customers, which helps increase engagement and build long-term loyalty.

Cost-Effective and Efficient

With tools like Wati, you can automate, schedule, and track messages all in one place. It saves both time and resources, making it a smart choice for growing businesses that want efficiency without extra costs. Here’s everything you need to know about Wati’s message-based pricing.

Easy to Track and Improve

When using WhatsApp Business API, you can access detailed broadcast analytics to track delivery, read, and response rates. These insights help you understand how your campaigns are performing and identify what needs improvement. Over time, this data allows you to refine your messaging strategy.

Ideal for Multiple Use Cases

WhatsApp broadcasts are highly versatile and suitable for any business type. You can send new product updates, service reminders, event invitations, or surveys directly to customers. Whether you are in retail, healthcare, education, or hospitality, broadcasts help you stay connected with your audience in a simple, effective way.

How to Get Better Results from Your Bulk WhatsApp Message Campaigns?

To get the most out of your WhatsApp bulk messaging campaigns, here are a few pointers to keep in mind.

Know Who You’re Talking To

Before sending your message, group your audience by what they like, where they are from, or what they have purchased before. When your messages speak to real interests, people are more likely to engage.

Keep It Short

Short messages work best. Focus on one main idea and keep your wording clear. Long messages can lose attention halfway, but short ones leave a stronger impression.

Double-Check Everything

Always send a test message before you broadcast. It is an easy way to spot typos, broken links, or formatting issues before your customers see them.

Review What Worked

After your campaign goes live, take a look at how it performed. Check delivery, open, and click rates to understand what worked well and what can be improved.

Try, Compare, Repeat

Experiment with different message styles, visuals, delivery times, and message tones. Reviewing the results will help you understand which messages drive the most engagement and guide future bulk messaging campaigns.

Create WhatsApp Message Templates That Capture Attention

Here are a few practical tips to keep in mind when creating WhatsApp message templates for broadcast campaigns.

Include a Clear Call to Action

Always guide your audience on what to do next. Use clear and simple instructions such as “Book now”, “Learn more”, or “Check out the latest collection”.

Ensure links function properly and direct users to the intended destination. A direct, easy-to-find CTA helps turn curiosity into action.

Make It Visually Engaging

Add relevant emojis, product photos, or short videos that match your message. For example, a café could share a picture of a new dessert, while a fitness studio could post a quick workout clip. Keep it neat and relevant so your visuals support your message instead of distracting from it.

Choose the Right Time

Timing can decide whether your message gets opened or ignored. Avoid sending messages too early or too late. Aim to send when your audience is most active, such as mid-morning or early evening. 

Offer Real Value

Every message should give something of worth to the reader. This could be a useful update, a helpful tip, or an exclusive offer. When customers find your messages relevant and rewarding, they start looking forward to hearing from you instead of skipping your updates.

Keep it Conversational

Write like you talk. Avoid a formal or very professional tone. Keep it friendly, natural, and conversational. For instance, say “Hope you’re doing well” instead of “We hope this message finds you in good health.” 

Collect More WhatsApp Opt-Ins with Click to WhatsApp Ads

Utilising Click-to-WhatsApp (CTWA) ads is one of the easiest ways to grow your WhatsApp audience. These ads appear on Facebook and Instagram and let people start a chat with your business in just one tap. 

Once they message you, you can easily collect consent and add them to your list of contacts for future updates and broadcasts.

Instead of sending people to a landing page or form, CTWA takes them straight into a WhatsApp conversation where you can answer their questions.

Compliant Ways to Build Your WhatsApp Opt-In List

Ask for Consent

Always let people know that they are agreeing to receive WhatsApp messages from your business. Being transparent helps you stay compliant and builds credibility with your audience.

Make Unsubscribing Simple

Allow users to opt out easily if they no longer wish to receive updates. A simple “Stop” or “Unsubscribe” reply should do the job. This keeps your contact list clean and ensures a positive experience.

Follow WhatsApp’s Business Messaging Guidelines

Adhere to WhatsApp’s business messaging policy by sending messages that are relevant, respectful, and add value. Avoid sending too many messages or using content that looks like clickbait. Quality messages will always outperform quantity.

Enhancing Bulk Broadcast Engagement with Retargeting

Retargeting helps to bring back the audience who have already interacted with your WhatsApp messages. By focusing on people who know your brand, you can 

• Improve engagement
• Drive conversions
• Make every broadcast campaign perform efficiently.

When done right, retargeting turns passive contacts into active conversations.

Make Your WhatsApp Broadcast Campaigns Work Harder with Retargeting

By combining retargeting with WhatsApp broadcasts, you can deliver more relevant, personalised messages that speak to each user’s stage in the journey.

Increases Engagement

Messages sent to users who have already shown interest in your brand are more likely to receive a response. Since these users are already familiar with your business, your messages tend to generate higher engagement from this audience segment.

Boosts Conversions

Retargeting helps nurture users who were close to making a decision but did not complete it. A timely reminder or personalised offer can guide them toward taking the next step.

Frequently Asked Questions

1. What are bulk WhatsApp broadcasts?
Bulk WhatsApp broadcasts let businesses send the same message to many contacts at once without creating a group chat. Each person receives it as a personal message, keeping the interaction private and one-on-one.
