Every few days, you must be receiving a WhatsApp message about your favourite brand’s latest offerings, the number of products it sold last quarter, details about its latest discount sale, or other important and relevant updates.
Since the message speaks directly to you, it feels personal and exclusive.
However, companies send these messages strategically to multiple users, not just you, by segmenting audience data and using WhatsApp Business API to boost engagement. This approach is quite common among businesses as WhatsApp consistently delivers an open rate of above 98%, compared to a mere 20% for emails.
If you’re still confused, worry not. This blog will help you learn how to send bulk WhatsApp messages, we’ll also discuss how tools like JoyzAI help you send compliant messages at scale without burdening your resources.
Let’s start with the basics.
What are Bulk WhatsApp Messages?
When you want your marketing communication to reach a good chunk of consumers simultaneously, you need to look beyond one-on-one chats. Bulk WhatsApp messages let you deliver the same message to a plethora of users from a verified business account. These messages can be promotions, updates, reminders, alerts, or support-related info.
Remember: a bulk message is not just comprised of text. You can also include:
- Images
- Videos
- Buttons
- Links
- Attachments
This ability makes WhatsApp a powerful, personalised outreach channel.
However, WhatsApp only allows bulk outreach if users opt in. Otherwise, you risk account suspension, spam complaints, or legal action. But by following the best practices you can both protect your brand’s reputation and keep your business running smoothly.

How to Send Bulk WhatsApp Messages
Today, there are several ways to send bulk messages on WhatsApp. The choice you make depends on your business size, goals, and tools.
A] WhatsApp Broadcast Lists
If you use the WhatsApp Business App, you can create a broadcast list. Follow these simple steps to create a successful broadcast list.
- Open the WhatsApp Business App on your mobile device
- Tap the three dots located in the top right corner
- Select the option labeled New broadcast from the menu
- Choose up to 256 contacts already saved in your contact list
- Type your message carefully, then tap Send to deliver it
This lets you send the same message to 256 contacts at once. It is simple, fast, and free. But it has limitations:
- You can only send to contacts who saved your number
- You cannot automate send times
- You cannot scale beyond a few hundred recipients
Broadcast lists work best for small businesses with a ready-made customer contact list.
B] WhatsApp Business API
When you need to send bulk WhatsApp messages to more than 256 users simultaneously, you need the official WhatsApp Business API platform. To access and use this API, you also need to work with a WhatsApp business solution provider (BSP), which enables account setup, message routing, compliance, and delivery at scale. Together, this provides a professional solution designed for automation, compliance, and performance tracking.
- Schedule campaigns
- Upload contacts easily
- Track message delivery and replies
- Use approved message templates
- Avoid spam complaints
Here’s how you can get started:
Step 1: Choose a WhatsApp API provider
You mustn’t rely on justthe regular app or broadcast lists for true bulk outreach. You must sign up with an official WhatsApp Business Solution Provider (BSP). BSPs simplify the technical setup and help you access the API quickly.
The API runs through trusted providers such as JoyzAI. These partners do all the heavy lifting so you can focus on fine-tuning your messaging.
Step 2: Verify your business
WhatsApp requires business verification through Meta Business Manager. You upload your business’s legal documents along with relevant details such as registered business name and website.
Once verified, your API account becomes ready and active.
Step 3: Upload your contact list
Prepare your contact list with phone numbers in international format (with country code). Make sure each person has opted in to receive messages. Then upload this file to your BSP dashboard.
This step prevents you from getting flagged as spam.
Step 4: Create message templates
WhatsApp only allows bulk outreach with approved templates. So, create your message in a structured format and submit it for approval through your BSP dashboard. Templates can include buttons, links, and media, and they must follow WhatsApp’s approval rules.
Once approved, these templates become reusable assets for future campaigns.
Step 5: Schedule or send your campaign
Select your approved template, choose your uploaded multiple contacts, and either send instantly or schedule for a specific date and time. You can target based on segments like new customers or loyal buyers.
Your BSP will handle the backend delivery via the WhatsApp Business API.
Step 6: Track results in your dashboard
After launching, monitor delivery rates, open rates, replies, and failure reports in real time. These insights help you improve your next campaign for better engagement.
C] Using WhatsApp Web
Some small businesses use WhatsApp Web for bulk outreach. It lets you operate WhatsApp on a computer while syncing with your phone. It can be faster than typing on a mobile phone’s keypad.
But it still relies on manual steps. It also does not let you scale or automate outreach. For serious campaigns, the WhatsApp Business API is a better choice.

Why WhatsApp Business API, Not WhatsApp Business, is Better for Sending Bulk Messages
Choosing the right platform matters. Here’s why many companies move away from the Business app:
- Professional setup: The WhatsApp Business API connects securely with tools such as CRMs and dashboards. You can automate messaging, track results, and build workflows that integrate with other systems. The Business app can send simple messages, but cannot handle high volumes without manual intervention.
- High volume capabilities: With the API, you can send messages to multiple contacts at once. You can easily target large segments of your customer list. You can also upload spreadsheets or integrate directly with tools in your tech stack. In contrast, the Business app limits the number of people you can message at a time and the number of lists you can create.
- Approval and template control: The API lets you create official message templates. WhatsApp reviews and approves these templates to protect users from spam. That means that when you send bulk WhatsApp messages, WhatsApp prioritises delivery and quality if your templates are approved and used correctly. You cannot leverage this structured template approval system in the Business app.
Creating and Approving Templates for Bulk WhatsApp Campaigns
When you plan to send messages at scale, templates make everything faster and safer. Instead of typing the same message again and again, you create a ready format that needs approval just once.
In short, a template is a pre-written message that WhatsApp reviews before you send it. Templates help WhatsApp confirm your message is timely, relevant, and expected by users. After approval, you can reuse that message in future campaigns without any delays.
Without an approved template, you cannot run a bulk campaign at scale through the API.
Complying with WhatsApp template guidelines
WhatsApp reviews every template to shield users from unwanted messages. This review process ensures that businesses send only clear, helpful, and expected communication.
To get your template approved, you must follow a few simple rules:
- Write clear and direct messages that explain the purpose of your campaign immediately
- Avoid misleading claims, exaggerated offers, or vague wording
- Keep the language simple and direct
- Mention your business name so users recognize the sender
- Do not include spam-like phrases or unnecessary emojis
Once you submit a template, WhatsApp reviews it within a short time. After approval, you can confidently use it for bulk campaigns without risking message failures or account warnings.
Using template variables for personalisation
Templates do not mean generic messages. WhatsApp allows you to add variables to personalise every message automatically.
These variables pull real customer information into the message, such as:
- Customer name
- Order or account reference
- Appointment date or delivery time
For example, instead of sending one flat message to everyone, the system inserts unique details for each recipient. Every user receives a message that feels like it’s written just for them.
This approach helps you:
- Build stronger customer trust
- Increase reply rates
- Improve conversions without manual effort
By combining approved templates with smart personalisation, you can send messages at scale while keeping conversations human, relevant, and engaging.
Compliance Checklist for Every Campaign.
| Before you send any bulk WhatsApp campaign, review this checklist carefully. Each step helps you protect your account and maintain customer trust. 1. User Consent- Always get permission from every contact before sending marketing messages. This step protects you from spam flags or complaints. 2. Respect Opt-Out Requests- Every message must let users opt out of future messages .You cannot ignore opt-out. Ignoring an opt-out can get you banned. 3. Use Approved Templates- Only send campaigns using templates approved by WhatsApp.Unapproved messages may fail or get your account blocked. 4. Include a Clear Sender Identity- Tell users who you are. This breeds trust and reduces confusion. 5. Avoid Spammy Language- Never use all caps, repeated symbols, or misleading links. Spam language increases complaints and reduces engagement. 6. Follow Local Regulations- Different countries have marketing laws. In India, you must follow telecom marketing rules and WhatsApp’s terms. |
How Brands Leverage Bulk WhatsApp Messaging to Improve Their Marketing Efforts
Several leading brands have used bulk WhatsApp messages to engage customers in creative and interactive ways. These examples highlight how WhatsApp marketing can drive awareness, engagement, and conversions.
1. Flipkart’s “Big Billion Days” interactive WhatsApp campaign
Flipkart, one of India’s largest e-commerce platforms, used WhatsApp to create excitement for its annual Big Billion Days sale. It built a conversational flow inspired by the famous quiz show Kaun Banega Crorepati (KBC), with Amitabh Bachchan acting as a virtual host.
Customers could interact through WhatsApp using images, audio, videos, emojis, and mini-games to explore the sale. They could solve puzzles and play emoji-enabled games while discovering new offers.
After just two weeks, the WhatsApp initiative achieved 3.5x more conversions, attracted 7x more high-quality visitors, and generated $2.5 million in revenue.
2. Adidas’s “Rent a Pred” campaign
Adidas focused on helping amateur football teams that often faced last-minute player dropouts. It created a WhatsApp hotline where teams could share match details.
Adidas responded by sending a top-quality substitute player to join the game. The system relied on automated messaging and interactive flows to quickly handle requests from multiple teams at once.
The initiative ran for six days (4-9 February 2020) and targeted a specific audience, but the impact was remarkable. Players brought in through this service achieved a 92% win rate and scored 29 goals across all games. The approach generated significant buzz in football media, retail websites, and blogs.
3. “NammaCop 24×7” WhatsApp initiative
The Chikkaballapur police in India made themselves more approachable through WhatsApp. Citizens can now send a message to contact numbers such as +9XXXXXXXXX to receive help instantly. The WhatsApp AI chatbot, powered by JoyzAI, understands queries, asks for area details, and provides relevant police station information, officer contact details, and guidance.
Through this initiative, SP Kushal Choksi aimed to create a people-friendly service that allows citizens to contact the police without the need to circumvent any bureaucratic obstacles. The chatbot handles multiple contacts, giving accurate responses and directing users to appropriate resources. Here are some of the features used while implementing the NammaCop 24×7 initiative:
- 24×7 availability with instant replies
- Access to all police services via WhatsApp messages
- Automated messaging that answers multiple questions simultaneously
- Multi-language support and contextual understanding
- Integration with JoyzAI’s WhatsApp bulk sender and chatbot capabilities
This initiative shows how WhatsApp bulk messaging and personalisation can improve public service delivery.
Sending Bulk WhatsApp Messages Using JoyzAI
If you want a simple and effective way to send bulk WhatsApp messages, JoyzAI makes the process seamless. Think of it as a smart assistant who handles customer conversations 24/7.
Sending bulk messages manually is time-consuming to say the least. But bulk messaging directly from WhatsApp risks your number being blocked. At the same time, using the WhatsApp API on your own is not possible.
WhatsApp Business API, Meta’s official platform, allows businesses to send bulk messages to your customer base safely and reliably. Designed with businesses in mind, it supports automated messaging, templates, and tools to manage large-scale campaigns.
Businesses cannot use WhatsApp API directly. To access it, you need a Business Solution Provider (BSP) like JoyzAI. Here’s what a BSP offers:
- Provides a ready-to-use platform built on the API
- Handles technical setup and ensures that bulk messaging complies with WhatsApp rules
- Offers detailed analytics, campaign tracking, and support so businesses do not have to manage complex integrations with third-party analytics solutions
This is only the beginning when it comes to sending bulk messages. Here’s what really happens.
Step 1: Set up your business

- Currency: Local currency for offers or payments
- Business Email: A verified email for your business account
- Timezone: Ensure messages are sent at the right local time
- Phone Number: The phone number customers can contact you on
Before completing the WACA setup, you pay a monthly platform fee of ₹1200 to Meta. When you connect your number, JoyzAI TSP (Trusted Service Provider) receives your name and profile picture. (NOTE: Doing this does not give JoyzAI access to post on your Facebook profile or view your personal profile. You must log in with an existing Facebook account.)
New accounts cannot be approved for Business Manager, and personal profiles remain private.
Once your number is connected, you can start creating WhatsApp campaigns safely.
Step 2: Create your WhatsApp campaign
- Use Meta-approved templates such as “Buy 1, Get 1 Free”
- Design messages for WhatsApp using text, images, buttons, or links
Step 3: Send to multiple contacts at once
