What is WhatsApp Broadcast?

WhatsApp broadcast is a convenient way for business accounts to simultaneously send mass messages to multiple contacts. Organizations can efficiently communicate with each client group in a single message. With the broadcast feature on WhatsApp Business or WhatsApp Business API channel, companies can easily reach many people in just one click.

A key benefit of using WhatsApp broadcast is its ability to target specific audiences with tailored messages. This makes it easier for businesses to personalize their communications and build customer relationships through relevant content. 

Additionally, because it uses end-to-end encryption technology, your messages are secure and private when sent via the broadcasting feature.

When sending a broadcast message on WhatsApp Business or the WhatsApp Business API platform, you can send several types of messages. 

For example, only texts, images, videos, audio files, documents like PDFs, links to websites, location information, contact cards containing names and phone numbers, as well as calendar events like reminders or appointments. 

Different available types of content allow businesses to create engaging campaigns to resonate with their audience while providing valuable information about the products or services they offer.

Broadcasts are sent directly from the sender’s device rather than through an external server, making delivery times much faster than traditional email marketing campaigns, which often take hours (or even days) to reach recipients’ inboxes due to spam filters blocking them along the way.

As such, this makes broadcasting ideal for time-sensitive announcements such as product launches or limited-time offers where speed is essential to maximize impact on potential buyers who may miss out if not informed promptly enough.

With the right strategies, the broadcasting feature on WhatsApp can be a powerful addition to any SMB’s marketing arsenal. Now let us look at how you can create your WhatsApp broadcast list.

How to Create a WhatsApp Broadcast List

Creating a WhatsApp “Broadcast List” is an essential part of any successful marketing campaign. By constructing a list tailored to those likely to interact with your messages, you can maximize the impact of your marketing efforts. To create an effective broadcast list, follow this step-by-step guide for managing it efficiently.

Step 1: Collect Contact Details

Collect and verify contact details from various sources such as customer databases, email lists, social media followers, etc. Before adding contacts to your list, ensure their information is accurate and up-to-date.

Step 2: Segment Your List

Once you have collected your contacts, it’s time to segment them into different groups based on their interests or demographics (age, gender, location). This will help you send more relevant messages and increase engagement rates.

If you send broadcast messages through WhatsApp Business app, you can create broadcast lists with up to 256 people in each list, allowing you to send personalized messages quickly and easily. 

To create a broadcast list, open the app and go to “Settings” > “Broadcast Lists”. Here, you will be able to name your list and add contacts from your address book or by manually entering phone numbers. Once you have added all the desired contacts, tap on the “Create List” button and your broadcast list will be ready.

Step 3: Create Automated Messages

Now that you have segmented your list into different categories, create automated messages for each group tailored specifically for them. This could include welcome messages when someone joins the broadcast list or reminders about upcoming events or promotions they may be interested in.

However, certain stipulations must be observed when broadcasting via WhatsApp Business. These restrictions include avoiding any promotional materials or advertisements not related to the product/service being offered by the business; excluding links that do not direct back to official websites; and abstaining from sending images containing nudity or graphic violence which would contravene WhatsApp’s terms of service if included in broadcasts sent out through its platform.

The lack of automation support within the app presents a major roadblock for businesses to streamline certain processes, such as follow-up messages after purchase or personalized marketing campaigns targeted towards specific segments of their audience base. This would likely be beneficial in terms of fostering engagement and boosting sales conversions without needing to dedicate additional resources to it on a daily basis.

Tips For Building An Effective List

Broadcasting via WhatsApp Business is a great way to stay in touch with your customers and foster connections. Below are some of the tips for building an effective broadcast list.

  • Use keywords throughout your messaging campaigns so that potential customers know what they’re signing up for when they join the broadcast list.
  • Personalize each message by addressing recipients by name.
  • Utilize A/B testing techniques to determine which type of content resonates best with each audience.
  • Encourage feedback from subscribers so that you can better understand their needs and preferences.

Moving on, let’s look at how you can send broadcast messages using the WhatsApp Business API platform. 

Limitations of WhatsApp Business App to Broadcast Messages

Limitations of using the WhatsApp Business app to broadcast messages are as the following. 

  • Time Consumption: Manually forwarding messages to each customer group is time-consuming and labor-intensive. It’s also difficult to track which customers have received the message and which ones haven’t.
  • Broadcast List Size Limitation: Even with Broadcast Lists, only up to 256 people can receive a single broadcast at any given time. This means businesses must create multiple lists for larger customer bases, resulting in even more manual work for employees responsible for managing these lists.
  • Employee Burnout Risk: Replying individually to hundreds or thousands of customers via WhatsApp can quickly become overwhelming for employees and lead them to burnout from having too much on their plate. Additionally, it can take away from other tasks they should focus on, such as providing quality customer service or developing new products and services.
  • Inadequate Automation Support: The lack of automation support within the app makes it hard for businesses to automate certain processes, such as follow-up messages after purchase or personalized marketing campaigns targeted towards specific segments of their audience base. These follow-up messages would help increase engagement and sales conversions significantly over time without needing additional resources invested into it manually every day.

Solution: Send WhatsApp Broadcast Messages With API

Before using WhatsApp Business API’s broadcasting feature, businesses must apply for a WAB API account through a verified Business Solution Provider. You can apply it via Chatalog to reduce the application barriers. Once approved, businesses can use the API to send messages to their customers on a larger scale.

With the WhatsApp Business API, small and medium business owners can send broadcast messages to their customers efficiently and effectively. The API allows businesses to connect with customers on a more personal level by enabling them to send customized, relevant messages. This increases customer satisfaction and helps build trust between businesses and their customers.


To ensure that customers receive only the content they want, users must opt in before they can receive broadcast messages from your business. This ensures that each message is tailored specifically to each customer’s needs or interests.


Applying for authentication through WhatsApp will help establish trust with new and existing customers as it verifies your company name with a “Green Tick” beside it when people search for you online.

Business Profile

When people click on your business account, they can quickly see all of the essential information about your company, such as branch addresses, service hours, website links etc., making it easier for them to contact you if needed.

How to Send a Broadcast Message on WhatsApp Business API

The WhatsApp Business API allows businesses to build custom solutions for sending automated messages, such as notifications or reminders.

The WhatsApp Business API provides more advanced features than available through the Business app alone. The API permits the configuration of automated notifications based on predetermined criteria, such as when a purchase is made. Additionally, there are powerful analytics tools included which let you track how many people opened or clicked through from your broadcasts so that you can optimize future campaigns accordingly.

Analyzing Results from Your Broadcasts

Measuring performance of your broadcasts is essential to understanding the success of your messaging campaigns. 

Assessing metrics such as open rates, click-throughs and user interaction can help you ascertain what is most effective for your company and intended audience. By tracking these performance indicators over time, you can identify trends in user behavior and optimize future broadcasts accordingly. 

Identifying areas for improvement requires analyzing both successes and failures from past broadcasts. It is essential to pinpoint any issues that hampered success or caused problems with earlier transmissions before relaying new messages. 

Moreover, look at any patterns that emerge from successful broadcasts: what type of content was used? What tone did it take? How was the CTA phrased? Answering these questions will help guide future efforts towards greater success.

Assessing the effects of your transmissions is a crucial move for guaranteeing that you are connecting with and captivating your intended interest group. By optimizing your broadcasts for maximum impact, you can increase open and click-through rates while also crafting content to reach a larger audience.
