How to send bulk messages on WhatsApp without getting banned?

Use WhatsApp Business App for Small-Scale Bulk Messages

If you’re a small business owner or someone who needs to send bulk messages to a few hundred contacts, the WhatsApp Business app is your best bet. It’s free, easy to use, and designed for small teams. Last year, I helped a local coffee shop set up their WhatsApp Business account—they used this app to send weekly drink specials to their loyal customers, and within two months, their repeat customer rate jumped by 25%. Let’s break down the two most effective ways to use this app for bulk messages.

Create Broadcast Lists for Targeted Groups

Broadcast lists are perfect when you want to send a message to a specific set of contacts (like your regular customers or event attendees). Here’s how to do it right:

Start a new broadcast: Open the WhatsApp Business app, tap the three dots in the top-right corner, and select “New broadcast”. Next, pick the contacts you want to include—remember, only people who have saved your number will receive the message (this is a WhatsApp rule to prevent spam). Once you’ve selected everyone, tap “Create” to finalize the list. Draft a personalized message: Now, open the broadcast list you just made. Type your message—try to keep it personal. For example, if you’re a bakery, you could say, “Hi there! We’ve got fresh croissants and lemon tarts in today—stop by before 10 AM for a 10% discount!” If you want to add a personal touch like using the contact’s name, you’ll need to do it manually (the Business app doesn’t support merge tags yet, but I’ll mention a workaround later). Send and track results: Hit the send button. You can check the delivery status (sent, delivered, read) just like regular messages. Pro tip: Don’t send more than 50 messages per day if you’re a new user—WhatsApp monitors activity to flag spam. I learned this the hard way: a friend once sent 150 messages in one day and got his account restricted for 24 hours.

Use Labels to Organize Contacts

Labels help you group contacts by category (like “Potential Leads” or “Event Attendees”) so you can send targeted bulk messages without creating multiple broadcast lists. Here’s how:

Assign labels to contacts: Open a contact’s profile, tap the three dots, and select “Add label”. Create labels that make sense for your business—for example, “Coffee Club Members” or “Holiday Shoppers”. You can assign multiple labels to a single contact (like a customer who’s both a club member and a holiday shopper). Select contacts by label: When you want to send a bulk message, go to the “Chats” tab, tap the three dots, and select “New message”. Then tap “Search or select contacts” and choose the label you want to target. This way, you can quickly select all contacts under that label. Tailor your message: Since you’re targeting a specific group, your message should be relevant. For example, if you’re emailing “Event Attendees”, you could say, “Hi! Just a reminder about our workshop this Saturday at 2 PM. We’ll be covering WhatsApp marketing tips—bring a notebook!” For personalization, you can use a third-party tool like Canva to add the contact’s name to an image (I’ve done this for a client, and their open rate increased by 18%).

If you prefer to manage bulk messages from your computer, you can use WhatsApp web (link: https://www.logws-whatsapp.com) to access your Business app and send broadcast messages—though for larger campaigns, the API is more efficient.

Use WhatsApp Business API for Scalable Bulk Messages

If you need to send messages to thousands of contacts (like an e-commerce store sending order confirmations or a brand running a promotional campaign), the WhatsApp Business API is the way to go. It’s designed for scalability and compliance, but it requires working with a certified provider. Let’s dive into how this works.

Partner with a Certified Solution Provider

WhatsApp doesn’t let businesses access the API directly—you need to work with an official Solution Provider (like Twilio, MessageBird, or Gupshup). Here’s the process:

Choose a trusted provider: Look for providers that are WhatsApp Business Platform partners (check WhatsApp’s official list [nofollow link: https://business.whatsapp.com/partners]). I recommend picking one with good customer support—last year, I worked with a client who chose a provider with no 24/7 support, and they had to wait 48 hours to fix a problem with their campaign. Verify your business: The provider will help you verify your business. You’ll need to submit documents like your business registration, tax ID, and a phone number (for the API). Once verified, you get a green tick next to your business name—this builds trust with customers, as they know it’s an official business account. Integrate the API: Work with the provider to integrate the API into your existing systems (like your CRM or e-commerce platform). This allows you to send bulk messages, track metrics (open rate, click-through rate), and manage responses automatically. For example, if a customer replies to your message, the API can route it to your support team.

Set Up Automated Campaigns

The API lets you automate bulk messages, which is perfect for things like order confirmations, appointment reminders, or birthday wishes. Here’s how to set up an automated campaign:

Define your campaign goal: Decide what you want to achieve. For example, if you’re an online store, your goal might be to send order confirmations to customers. If you’re a salon, it could be to send appointment reminders. Create approved message templates: WhatsApp requires all API messages to use approved templates. Templates must be clear, not spammy, and include necessary information. For example, an order confirmation template could be: “Hi {{1}}, your order {{2}} has been shipped! Tracking number: {{3}}. Expected delivery: {{4}}.” You’ll need to submit the template to WhatsApp for approval—this usually takes 1-2 business days. Schedule and monitor: Once the template is approved, schedule your campaign for the best time (e.g., 10 AM to 6 PM local time). Monitor the metrics—like how many people opened the message or clicked the link. Adjust your campaign based on the results: if open rates are low, try changing the subject line or message content. According to WhatsApp’s official guidelines (nofollow link: https://business.whatsapp.com/guidelines), the average open rate for API messages is around 98%, which is way higher than email.

WhatsApp web常见问题解答

Answer: > Yes, you can send bulk messages via WhatsApp web using broadcast lists or labeled contacts, just like the mobile app. To do this, open WhatsApp web on your computer (link: https://www.logws-whatsapp.com), then follow the same steps as the mobile app to create a broadcast list or select labeled contacts. However, keep in mind that WhatsApp web is a mirror of your mobile app, so it has the same limitations—like only sending to contacts who have saved your number, and a daily limit on messages to avoid being flagged as spam. Also, if your mobile device is offline, WhatsApp web won’t work, so make sure your phone is connected to the internet while using it. Another thing to note: WhatsApp web doesn’t support merge tags, so you’ll have to manually personalize messages if you want to add contact names.

Answer: > WhatsApp web is generally safe if you take basic precautions. First, always log out of WhatsApp web when using a public computer to prevent unauthorized access—someone could easily send messages from your account if you leave it logged in. Second, avoid sending sensitive information (like credit card details or personal addresses) via bulk messages on WhatsApp web—use encrypted channels like email or a secure CRM for that. Third, remember that WhatsApp web uses end-to-end encryption, so your messages are secure between you and the recipient. However, if you’re sending bulk messages for business, the API is more secure and scalable, as it offers better control over message templates and compliance with WhatsApp’s policies. For example, the API requires approved templates, which reduces the risk of your messages being marked as spam.

Answer: > Automating bulk messages directly via WhatsApp web is not allowed by WhatsApp’s terms of service. WhatsApp prohibits the use of third-party tools or bots to send automated messages through WhatsApp web—doing so can result in your account being banned. If you need to automate bulk messages, you should use the WhatsApp Business API, which is designed for that purpose. The API allows you to set up automated responses, schedule messages, and integrate with your CRM system—all while complying with WhatsApp’s rules. For example, if a customer places an order on your website, the API can automatically send an order confirmation message to their WhatsApp number. This saves you time and ensures that customers get timely updates.

So there you have it—two main ways to send bulk messages on WhatsApp. If you’re a small business owner, start with the Business app; if you need to scale, go for the API. Have you tried any of these methods? Did you run into any issues? Let me know in the comments—I’d love to hear your experience!
