In today’s fast-paced digital world, communication is key. Whether you’re a business owner looking to engage with customers or an individual wanting to send personalized messages to friends and family, WhatsApp has become the go-to platform for instant and secure messaging. One of the most powerful features of WhatsApp is its ability to send bulk messages, allowing users to reach a large audience quickly and efficiently. This guide will walk you through everything you need to know about sending WhatsApp bulk messages, from the basics to advanced strategies.
What Are WhatsApp Bulk Messages?
WhatsApp bulk messages are a way to send the same message or slightly personalized messages to a large number of users at once. This feature is particularly useful for businesses that want to announce sales, share updates, send appointment reminders, or re-engage old leads. For example, a coaching business might use WhatsApp to send weekly motivational messages to students, while an e-commerce business might send order updates or seasonal discount codes to thousands of users.
What makes this feature powerful is that it allows you to meet users where they’re most active — their WhatsApp inbox. Unlike emails that might get buried or SMS that feels too intrusive, WhatsApp is both personal and effective. That’s why more businesses are turning to WhatsApp to drive engagement.
But sending bulk messages on WhatsApp isn’t just about writing a message and hitting “send.” It’s about choosing the right channel and doing it safely and smartly. That’s what we’ll help you figure out in this guide.
How to Send Bulk Messages on WhatsApp
There are two main ways to send bulk WhatsApp messages:
- WA Sender – Easiest Way for Everyone
- WhatsApp Business API – For Serious Scale
Let’s break both down.
Option 1: WA Sender – Easiest Way for Everyone
WA Sender is a Chrome-based bulk WhatsApp sender tool designed for business users who want to send bulk messages without needing any coding or technical setup. It works directly on WhatsApp Web and helps you send messages to multiple contacts with ease.
This makes it ideal for small businesses, freelancers, and anyone who wants to quickly send WhatsApp bulk messages to a list of leads or customers. You don’t need developer support or Facebook verification. It’s plug-and-play.
You can use it to send personalized bulk messages, schedule campaigns, attach images or PDFs, and even track delivery — all in a few clicks. Plus, you can upload contacts directly from Excel or CSV files. This kind of tool makes bulk WhatsApp marketing accessible to everyone.
How to Send Bulk Messages via WA Sender (Step-by-Step)
-
Install WA Sender Extension
Head over to wasender.com and click on ‘Install for Free’ to install the Chrome extension. This acts as your dashboard for creating and managing campaigns. -
Open WhatsApp Web
Open WhatsApp Web on your browser and scan the QR code with your phone. WA Sender works on top of your existing WhatsApp interface. -
Upload Contacts
Prepare a list of WhatsApp contacts in Excel or CSV format. You can include name, number, email, or any custom field. WA Sender also lets you filter contacts to remove invalid or non-WhatsApp numbers. This saves time and reduces delivery issues. -
Write Your Message
Craft your message. You can create personalized messages using placeholders like {name}, {email}, or {company}. These will automatically be replaced with actual data from your uploaded file.
For example:
“Hi {name}, your order is ready for pickup! Click here to confirm.”
This makes messages feel less like a blast and more like a 1-on-1 chat, increasing engagement and reducing complaints.
-
Send Bulk Messages
Now hit “send.” WA Sender starts sending your messages one by one — mimicking human behavior to avoid getting flagged. You can set delays between messages, batch size, and other anti-ban precautions. -
Track Replies and Deliveries
View how many messages were delivered, read, or replied to. This helps you improve your future messaging strategy and optimize performance.
Bonus: You can send images, PDFs, invoices, links, and even videos — making your bulk messages more interactive.
Option 2: WhatsApp Business API – For Serious Scale
For businesses that need automation, CRM integration, chatbots, or compliance, the WhatsApp Business API (WABA) is the gold standard. This is WhatsApp’s official offering to help businesses communicate with their customers at scale.
But it’s not a plug-and-play solution. You need to:
- Apply for a WhatsApp Business Account
- Use a solution provider
- Verify your business app
- Set up pre-approved message templates
Once approved, you’ll be able to send bulk messages via API — programmatically or through third-party dashboards.
How to Get Started with WhatsApp Business API
-
Register with a Business Solution Provider (BSP)
WhatsApp doesn’t offer the API directly. You’ll need to sign up through an approved BSP like Twilio, AiSensy, Wati, or WASender. These partners help you manage your WhatsApp Business Account and provide a dashboard or API access. -
Verify Your Business on Facebook Business Manager
You’ll need to verify your business identity in Facebook Business Manager. This includes uploading documents and confirming your business domain. -
Set Up a WhatsApp Business Account
Once verified, create your WhatsApp Business Account. This allows you to configure your display name, phone number, and API access. -
Submit Message Templates
The WhatsApp Business API doesn’t allow you to send arbitrary messages to users who haven’t opted in. You must use pre-approved message templates for initial outreach. These are short, structured messages like “Hi {name}, your order has been shipped.”
Approved message templates help you stay compliant with WhatsApp’s rules and avoid bans.
-
Use a Dashboard or API
Depending on your setup, you can send bulk WhatsApp messages through a dashboard or automate it with a developer. -
Monitor Analytics
Track open rates, delivery stats, and even automate re-engagement workflows. You’ll have access to analytics like delivery status, read receipts, response rates, and chatbot interactions, helping you refine your campaigns. This method is ideal for businesses handling customer support, appointment bookings, e-commerce, or large-scale campaigns.
Benefits of Sending WhatsApp Bulk Messages
Let’s talk about why more businesses are shifting their focus to WhatsApp bulk messaging.
1. High Open Rates
WhatsApp messages boast open rates as high as 98%, significantly higher than emails. If you want your messages to be seen — and seen fast — WhatsApp wins.
2. Real-Time Communication
Whether it’s a flash sale, emergency alert, or delivery update, WhatsApp allows you to reach your audience instantly. No delays, no junk folders.
3. Personalization at Scale
Using fields like {name}, {order_id}, or {city}, you can send personalized messages to thousands of users in one go. It’s the secret to higher replies and fewer unsubs.
4. Cost-Effective
Unlike traditional SMS or call centers, sending WhatsApp messages is often cheaper and more efficient. WA Sender, for instance, offers freemium options for starters.
5. Rich Media Support
You’re not limited to text. Send invoices, product images, catalogs, and video tutorials directly into your customer’s WhatsApp inbox.
6. Two-Way Conversations
Unlike email or SMS, WhatsApp supports real-time replies. Customers can ask questions, confirm bookings, or engage directly, creating stronger relationships.
Best Practices for Sending Bulk WhatsApp Messages
Sending bulk messages is powerful — but only if done right.
1. Avoid Unsolicited Messages
Always get user consent before messaging. Unsolicited messages violate WhatsApp policies and may get your number blocked. Use opt-in checkboxes on your website, forms, or during checkout.
2. Use Personalization
Don’t send the same message to everyone. Customize messages using fields like {name} or {city}. This makes your campaign feel tailored and avoids sounding robotic.
3. Respect WhatsApp Rules
Avoid triggering spam filters by not using banned keywords, shortened links, or deceptive content. Read up on WhatsApp’s messaging guidelines to stay compliant.
4. Batch Smartly
If you’re using a wa bulk message sender like WASender, don’t send 500 messages at once. Use batches of 50–100 with gaps of 10–15 seconds to mimic real user behavior.
5. Time it Right
Avoid sending messages during odd hours. Understand your audience’s active time and send accordingly — ideally during mid-morning or early evening.
Tips to Create Engaging WhatsApp Message Templates
Whether you’re using the API or WA Sender, your message templates make or break your campaign.
Start Strong
Open with context like “Hey Rohan, thanks for attending our webinar yesterday!” to capture attention immediately.
Use a Human Tone
Avoid corporate jargon. Talk like a friend or trusted advisor. This makes your messages more engaging and less promotional.
Be Concise, But Clear
WhatsApp is a quick-read platform. Keep your message short but informative. Every line should add value.
Include a Call to Action
Guide users with CTAs like “Tap to buy now” or “Reply YES to confirm.” A clear next step improves conversion rates.
Remember, all outbound messages via the WhatsApp API must be pre-approved message templates. So keep it clean and compliant. Click this link to learn how to create stunning attachments for your messages.
How to Unban a WhatsApp Number if it Got Banned
If your WhatsApp number got blocked after sending bulk broadcasts, don’t panic. It happens if:
- You sent messages too aggressively.
- Your messages felt spammy or irrelevant.
- You violated WhatsApp’s terms by scraping or cold-blasting users.
Steps to Recover
-
Stop all activity immediately
Continuing to send messages after a ban will worsen the situation. -
Appeal via WhatsApp support
Open the app and submit a request or go through Facebook Business Support. Explain your case. -
Be polite.
Explain your use case, and ensure compliance with WhatsApp policies. -
Switch Numbers if Needed
If you’re permanently banned, switch to a new number — but improve your practices. Warm Up Slowly
Send messages to engaged users first. Use personalization. Avoid sending 500 messages on day one.
Using a trusted bulk WhatsApp sender tool like WA Sender helps reduce these risks by including features like delays, batching, and smart filtering.
Wrapping It Up
Learning how to send bulk messages on WhatsApp opens up a powerful, direct line to your audience. Whether you’re a small business using a bulk message sender like WA Sender or a growing brand tapping into the WhatsApp Business API, the real magic lies in delivering personalized messages that feel human.
Stick to the WhatsApp rules, use message templates smartly, and prioritize value over volume.
So what’s next? Try sending your first bulk broadcast WhatsApp messages with a tool like WA Sender — it’s free to start and easy to scale.
