How to Send Bulk WhatsApp Messages without getting banned
Sending mass messages via WhatsApp has become one of the most effective communication strategies for companies of all sizes. However, doing it the wrong way can result in the permanent banning of your numberIn the worst case, the loss of your conversation history and, in the worst case, the disabling of your WhatsApp Business account.
In this article we explain why accounts are banned, what are the safe methods to send mass messages and how you can escalate your broadcast campaigns without jeopardizing your business operation.
The Problem: Why WhatsApp Bans Accounts that Send Bulk Messages
Meta, the company that owns WhatsApp, has strict policies against spam and misuse of its platform. Every day, thousands of business accounts are restricted or permanently banned for violating these policies, often without the owner understanding exactly what they did wrong.
The main reasons why an account is banned include:
Use of Unofficial Tools
Third-party applications that promise to send thousands of "free" messages often use unauthorized methods to access WhatsApp. These tools modify the WhatsApp client, simulate human behavior using unapproved bots or exploit vulnerabilities in the platform. Meta detects these patterns easily and applies immediate bans.
2. Sending Spam and Unsolicited Messages
Sending messages to people who have not given their explicit consent is one of the most serious violations. When recipients report your messages as spam or block your number, WhatsApp interprets this as a clear sign that you are abusing the platform.
3. Excessive Volume in a Short Time
Sending hundreds or thousands of messages in a very short period of time generates automatic alerts in Meta detection systems. Even if your contacts are legitimate, a sudden spike in activity can be interpreted as unauthorized automated behavior.
4. Low Quality Score
WhatsApp assigns a quality score to each business phone number connected to the API. This rating is based on how recipients respond to your messages in the last 24 hours. A high number of blocks or reports degrades your score quickly.
5. Prohibited or Deceptive Content
Messages with misleading content, false offers, suspicious links or information that violates Meta's business policies result in immediate restrictions.
The Risks of Ignoring WhatsApp Policies
The consequences of sending mass messages incorrectly go beyond a simple annoyance:
- Temporary ban: Your account is restricted for hours or days, preventing you from sending messages.
- Permanent ban: Total loss of phone number and all conversation history.
- Message limit degradation: Meta reduces your sending capacity from thousands to just a few dozen messages per day.
- Loss of business verification: If your Meta Business account is flagged, you lose access to advanced features.
- Reputational damage: Customers who receive spam associate your brand with invasive practices.
Secure Methods to Send Mass Messages by WhatsApp
The good news is that there are completely safe and Meta-approved ways to send mass mailings. Here are the five fundamental pillars.
Method 1: Using the Official WhatsApp Business API with Approved Templates
The WhatsApp Business API (also known as WhatsApp Cloud API) is the only official channel that Meta recognizes for mass sending at scale. Unlike the regular WhatsApp Business application, the API allows:
- Send messages to thousands of contacts programmatically.
- Use pre-approved Meta message templates.
- Integrate shipping with your CRM, marketing platform or management system.
- Access detailed delivery and reading metrics.
How it works: Before sending any mass message, you must create a message template and submit it to Meta for approval. Templates can include text, images, videos, documents, interactive buttons and custom variables. Once approved, you can use it to send messages to all your contacts who have given their consent.
Types of templates allowed:
- Order confirmations and shipping updates.
- Appointment reminders.
- Account notifications.
- Promotions and offers (with prior consent).
- Welcome messages and post-purchase follow-up.
Method 2: Quality Rating Management
Meta assigns three quality levels to your business number:
| Rating | Color | Meaning |
|---|---|---|
| High | Green | Excellent user feedback |
| Media | Yellow | Some reports or blockages detected |
| Download | Red | High number of reports, risk of restriction |
How to keep your rating high:
- Monitor your quality dashboard daily in WhatsApp Business Manager.
- If your rating drops to yellow, immediately reduce your shipping volume.
- Review the content of your templates and make sure they are relevant to your audience.
- Remove from your contact list those who do not interact with your messages.
- Segment your audience to send personalized and relevant content.
Method 3: Gradual Increase of Sending Limits (Ramp-Up)
Goal establishes messaging limits by level (tiers) that determine how many unique contacts you can reach in a 24-hour period:
| Level (Tier) | Unique Contacts for 24 Hours |
|---|---|
| Tier 1 | 1,000 contacts |
| Tier 2 | 10,000 contacts |
| Tier 3 | 100,000 contacts |
| Tier 4 | Unlimited |
How to level up:
- Start sending messages at a low volume within your current tier.
- Maintains a consistently high quality rating (green).
- Send messages to at least 50% of your current limit for a period of 7 days.
- Meta automatically promotes you to the next tier if you meet these criteria.
Recommended ramp-up strategy:
- Week 1: Send to 200-500 contacts per day.
- Week 2: Increase to 500-1,000 contacts per day.
- Week 3: If your rating remains green, scale to 2,000-5,000.
- Week 4 onwards: It continues to increase gradually.
The key is never to make sudden jumps in volume. An organic and sustained increase is what Meta interprets as legitimate behavior.
Method 4: Use Opt-In Verified Contacts Only
He opt-in (explicit consent) is not only a good practice, it is an mandatory requirement of the WhatsApp Business policy. Before sending any mass messages, you must make sure that each contact has given clear permission to receive communications from you via WhatsApp.
Valid ways to obtain opt-in:
- Forms on your website with a specific box for WhatsApp.
- Welcome message when the customer initiates the conversation first.
- Point-of-sale registration with documented consent.
- Subscription flows within other platforms (email, social networks).
- QR codes that lead to a WhatsApp link with a predefined message.
NOT valid forms of opt-in:
- Buy telephone number databases.
- Extract numbers from WhatsApp groups.
- Assume consent because the customer gave you their number for another purpose.
- Manually add contacts without your knowledge.
Method 5: Best Practices for Message Templates
A well-designed template is not only more likely to be approved by Meta, but also drastically reduces the rate of blocking and reporting.
Ideal staffing structure:
- Personalized greeting: Use variables to include the contact name.
- Immediate context: Explain in the first line why you are writing to him.
- Clear value: The recipient must understand the benefit within the first 3 seconds.
- Call to action: A single clear CTA (quick response button or URL).
- Exit option: Indicates how to stop receiving messages.
Example of an effective template:
Hello {{name}}, we are {{company}}.
Your order #{{order_number}} has been shipped and will arrive on {{delivery_date}}.
You can track your shipment here: {{url_tracking}}
If you have any questions, please contact us here. To stop receiving notifications, type EXIT.
Common errors in templates:
- Use overly promotional language ("UNPREDICTABLE OFFER", "FREE", "BUY NOW").
- Do not include opt-out option.
- Send the same template repeatedly without variation.
- Include multiple calls to action that confuse the user.
How to Recover Your Account from a Low Quality Rating
If your rating is already in the red, all is not lost. Follow these steps to recover:
- Immediate pause: Stops all mass mailings for at least 48-72 hours.
- Audit your contact list: Eliminate inactive, invalid or never answered numbers.
- Check your templates: Identify which template generated the most reports and pause or modify it.
- Restart with minimum volume: When you resume, do it with no more than 100-200 messages per day.
- Segment aggressively: Send only to contacts who have interacted with you in the last 30 days.
- Monitor daily: Check your rating every 24 hours for the next 2 weeks.
Meta re-evaluates your rating on an ongoing basis. If you demonstrate a responsible shipping pattern, your score can be restored within 7 to 14 days.
The Limits of Goal Messaging: What You Should Know
In addition to the unique contact numbers, Meta imposes other important restrictions:
- 24-hour window: You can only send free messages (without template) within 24 hours after the last message from the customer.
- Template messages: They are the only way to initiate conversations outside of the 24-hour window.
- Cost per conversation: Meta charges for each 24-hour conversation initiated, with rates varying by country and message category.
- Conversation categories: Utility, Authentication, Marketing and Service, each with different rates and rules.

Frequently Asked Questions (FAQ)
How many messages can I send per day on WhatsApp Business without being banned?
The limit depends on your tier in the official WhatsApp Business API. New numbers start at Tier 1, which allows you to reach up to 1,000 unique contacts in 24 hours. This limit can grow to be unlimited if you maintain a good quality score. If you use the regular WhatsApp Business application (not the API), there is no official published limit, but sending more than 256 messages per day to contacts who do not have your address book can generate restrictions.
2. What is the difference between the WhatsApp Business app and the WhatsApp Business API?
The WhatsApp Business application is free and designed for small businesses with low message volume. The WhatsApp Business API is an enterprise solution that requires an authorized provider (such as Aurora Inbox) and allows you to send bulk messages at scale, integrate with external systems, use multiple agents and access advanced automation features. Only the API is officially approved for bulk sending.
3. What do I do if my WhatsApp Business account has already been banned?
If you received a temporary ban, wait the indicated time and modify your posting behavior. If the ban is permanent, you can appeal through the official Meta form, although the success rate is low. The best strategy is to migrate to the official WhatsApp Business API with a new number and start with safe practices from the beginning. Aurora Inbox can help you set up a new number with the official API and establish a secure ramp-up plan.
4. Is it safe to use third party tools that promise free mass mailings?
No. Unofficial tools that promise free mass mailings often violate WhatsApp's Terms of Service. These applications use unauthorized methods that Meta detects with increasing accuracy. The risk of permanent banning is extremely high, and you also jeopardize the security of your customers' data. The only safe way to send bulk messages is through the official WhatsApp Business API.
5. How long does it take Meta to approve a message template?
The template approval process generally takes from a few minutes to 24 hours. In some cases it can take up to 48 hours. To speed up approval, make sure your template complies with Meta's commerce policies, does not contain prohibited content, includes a clear purpose and is not overly promotional. If your template is rejected, you can edit it and resubmit it for further review.
Sending mass WhatsApp messages securely is not complicated if you follow the rules established by Meta. The key is to use the official API, maintain a list of contacts with verified consent, respect the sending limits and constantly monitor your quality score. With the right tools like Aurora Inbox, you can scale your WhatsApp campaigns without putting your account and customer relationships at risk.
