What is a WhatsApp Bulk Message?
Simply put, WhatsApp bulk messages are messages sent simultaneously to multiple recipients on WhatsApp. Businesses can reach a large number of customers effortlessly, making it one of the best marketing and remarketing tools.
3 Benefits of WhatsApp Bulk Message
WhatsApp bulk messages provide numerous advantages that make them an attractive option for businesses to interact with their target audience.
1. Direct and Convenient Interactions
WhatsApp provides a platform for businesses to connect directly with customers, allowing them to build strong relationships on the platform they use daily to chat with family and friends.
2. Exceptional Engagement Rates
Messages sent via WhatsApp see an impressive open rate of up to 98%, significantly surpassing the average 21.3% open rate for email campaigns, resulting in better responsiveness and reach.
3. Multimedia Content Sharing
Businesses can use WhatsApp to share multimedia content such as images, videos, documents and even catalogs, making communication more engaging and informative
WhatsApp offers 2 bulk messaging solutions to cater to different business sizes and messaging needs — the WhatsApp Business App and the WhatsApp Business Platform (also known as WhatsApp API). Let’s first talk about WhatsApp bulk messages on the WhatsApp Business App.
How to Send Bulk Messages with WhatsApp Business App in 3 Steps
In general, the WhatsApp Business App works for micro and small businesses. It’s free, easy to use and doesn’t rely on external software to send broadcasts. Just ensure that the number you are using is different from your personal number.
Here’s how to send bulk messages on the WhatsApp Business App for free in 3 steps.
Step 1: Start a New Broadcast
Open WhatsApp and tap the 3 dots in the upper-right corner of your screen. From the menu, select New Broadcast to create a new broadcast list.
Step 2: Create a Broadcast List Containing Up to 256 Contacts
You’ll see a list of your contacts. Choose the ones you want to include in your broadcast list. Remember, recipients must save your number in their contacts to receive your broadcast messages.
Optionally, assign a name to your broadcast list to organize and manage different audience segments more efficiently.
Step 3: Compose Your Message and Send It
After creating the list, a chat window resembling a group chat will open. Here, you can compose your message, attach multimedia such as images or videos, and even share items from your WhatsApp Catalog. Once ready, hit the send button.
Each recipient will receive the message as an individual chat, preserving privacy and personalization. As mentioned, the WhatsApp Business App is not a viable broadcast tool for medium or large enterprises. Let’s take a look at why.
4 Limitations of Sending Bulk Messages with WhatsApp Business App
Before using the WhatsApp Business App, you need to be aware of a few things. Sending bulk messages with WhatsApp Business App has some limitations.
For starters, it’s not possible to import contact lists. Instead, phone numbers must be manually added one by one. But there’s more.
1. Contacts Must Save the Sender’s Number
The WhatsApp Business Policy prohibits businesses from spamming, so contacts must save the sender’s number on their phones to receive broadcasts. Make sure all the contacts in the WhatsApp Broadcast list have saved your number in their address book.
2. Limited Number of Contacts per Broadcast List
While there is no limit to the number of Broadcast lists you can create, you can include up to 256 contacts in each broadcast list. As your business scales, you will need an easy way to reach more than 256 people at once without creating multiple broadcast lists.
3. Limited Number of Devices
You can use WhatsApp Business App on a maximum of 5 devices at the same time. However, only one of those devices can be a phone.
4. Lack of Broadcast Analytics
WhatsApp Business App doesn’t offer any analytics tools to measure the performance of WhatsApp broadcasts. You will not have insights into broadcast message delivery and other important metrics.
If your WhatsApp marketing and sales operations can’t be limited, what can you do? You should consider using WhatsApp API.
The Solution? Send bulk messages with WhatsApp API
WhatsApp API, also known as WhatsApp Business Platform, is designed for medium to large companies looking to use WhatsApp for messaging at scale. Unlike the WhatsApp Business App, the API has no front-end interface and must be connected to messaging software to send and receive messages.
This gives businesses the freedom to choose a software solution that fits their business needs and have access to advanced features, such as automating conversations and appointment booking, AI tools, sending broadcasts, and more to create personalized customer journeys.
WhatsApp Business App vs WhatsApp API
The differences between the WhatsApp Business App and WhatsApp API mainly lie in the scalability of each service.
Compared to the WhatsApp Business App, WhatsApp API can have an unlimited number of agents. This lets businesses add any number of agents to their operations under one account. Whereas you’d need to get multiple numbers once you need to use more than 5 devices on WhatsApp Business App.
This level of scalability extends to the number of bulk messages sent. On WhatsApp API, businesses can send an unlimited number of bulk messages, though this depends on the status of your account.
Furthermore, WhatsApp API supports advanced automation capabilities and 3rd-party software integration that speeds up common tasks and processes like lead qualification. This frees up your agents’ time to focus on more important things like closing a sale.
So, now that you know the differences between the 2 WhatsApp services, what should you look for in a WhatsApp bulk message sender?

There are 4 steps in getting a WhatsApp API Account.
Step 1: Port or Buy a Phone Number
You need a phone number to set up your WhatsApp Business API account. You may port an existing phone number as long as you can receive calls or SMS. Just make sure that it is not connected to any WhatsApp, WhatsApp Business App or WhatsApp API accounts.
To use a phone number tied to an existing WhatsApp or WhatsApp Business App account, you’ll first have to delete that account.
<call-out> Using a phone number tied to an existing WhatsApp or WhatsApp Business App account will result in a permanent loss of existing contacts and messages. <call-out>
Step 2: Connect Your Facebook Account
To set up the respond.io WhatsApp API integration, start by creating and connecting a new WhatsApp Business Platform (API) account. Complete the eligibility checks, then log in with your Facebook account to connect your WhatsApp Business API to respond.io.
This will grant respond.io permission to manage your WhatsApp Business account, including handling billing. You also need to agree to the WhatsApp Business Terms of Service and the Meta Terms of Service.
Step 3: Connect Your WhatsApp Business API Account to Respond.io
Select your verified Meta Business Portfolio. If you don't have one, create a new account. If you're porting a WhatsApp number, select an existing business account.
Then, create a new WhatsApp Business profile by providing key details such as the account name, display name, business category, and timezone. A business description and website are optional.
Step 4: Verify your WhatsApp Business Phone Number
After adding and verifying your WhatsApp Business phone number via text or call, finalize the setup by selecting the number to connect. Once complete, your business will initially be unverified while WhatsApp conducts a Commerce Policy check.
If blocked for non-compliance, you can appeal through your BSP's support. For further guidance, visit respond.io’s Help Center.

4 Tips to Avoid WhatsApp Bulk Messages Being Marked as Spam
To avoid being marked as spam when sending bulk messages on WhatsApp, there are several strategies you can implement.
1. Only Use Bulk Messages for Retargeting Campaigns
Only send bulk messages to contacts that have opted-in to receive promotional and marketing messages. Before adding recipients to your broadcast list, always ensure you have obtained their explicit opt-in consent. Clearly communicate the type of messages they will receive and provide an easy opt-out option. This helps to establish a foundation of trust and respect for their privacy.
2. Follow WhatsApp’s Terms and Conditions
Take the time to understand the WhatsApp Business Business Messaging Policy before sending bulk messages. By complying with these rules, you can maintain a positive reputation and avoid being flagged as spam.
3. Don’t Send Too Many Messages At Once
Avoid excessive messaging that might overwhelm recipients. Respect a reasonable frequency for sending bulk messages, ensuring that recipients are not bombarded with an excessive amount of communication.
4. Make Sure Your Messages Are Relevant
It is crucial to send messages that are relevant and valuable to your recipients through WhatsApp bulk messages.
Avoid bombarding them with frequent, generic, or irrelevant messages, as this can lead to being perceived as spam. Tailor your content to the specific needs and interests of your audience to increase engagement.
