How to Get WhatsApp (WA) Blast Easily

There are two ways to obtain a WA Blast: officially and unofficially. It should be noted that you should use an official WA Blast via the WhatsApp Business API to build long-term brand awareness.

Furthermore, you can also access features that support the sales and marketing process, such as integration with CRM systems, omnichannel, and chatbots through the official WhatsApp Business API.

The following is how to get a WhatsApp blast from Mekari Qontak as an official WhatsApp Business API partner.

1. Register with Official BSP Mekari Qontak

The first step is to register with the official BSP Mekari Qontak as an intermediary with Meta. This process is important so that you can use the WhatsApp Business API officially.

2. Connect a Facebook Business Manager Account

After registering with Mekari Qontak, you need to connect a Facebook Business Manager account (or Meta Business Account). If you do not have an account yet, you will be directed to create a Meta Business Account first.

3. Create a WhatsApp Business Account and WhatsApp Business Profile

Next, create a WhatsApp Business Account and WhatsApp Business Profile. At this stage, you need to prepare a new phone number that has never been connected to the WhatsApp Messenger application or Business App.

4. Mekari Qontak WhatsApp Business API Account is Ready to Use

The WhatsApp Business API is ready to be used if the account is approved by Meta within 5 until 7 working days. You can utilize features such as blast, personalization, and CRM integration.

Differences Between Official vs Unofficial WhatsApp Blast

Below are the differences between official and unofficial WhatsApp blast that are important for you to understand to ensure data security and the trust of your business customers.

1. Official WA Blast

Basically, official WA Blast is a method of sending mass messages via WhatsApp that is approved and regulated directly by the WhatsApp Business API.

To use Official WA Blast, businesses cannot directly register with WhatsApp. You must work with an official WhatsApp Business Solution Provider (BSP), such as Mekari Qontak as a trusted partner.

Through official WA Blast, message delivery can be done without needing to save contact numbers first and the number of recipients is not limited.

In addition, official WA blasts are generally equipped with certification to guarantee customer data security, such as the WhatsApp Business API from Mekari Qontak, which is ISO/IEC 27001:2022 certified.

2. Unofficial WA Blast

Unlike the official WA Blast, an unofficial WA Blast refers to any form of mass messaging via WhatsApp that is not approved or allowed by WhatsApp.

Unofficial WA Blast can be obtained from third-party software, desktop software, and unauthorized modifications. These applications are not directly connected to the official WhatsApp Business API.

The use of unofficial WA blast is certainly very risky, such as threats of malware, data theft, and potential reputational loss for your business. Below is a table of differences between official and unofficial WA Blast.

Use Left/Right arrow keys to scroll horizontally.

Comparison	Official WA Blast	Unofficial WA Blast
Legality	Legal and recognized by WhatsApp through official partners.	Illegal and not approved by WhatsApp; risk of violating Usage Policies.

Integration & Scalability	Seamlessly integrates with CRM/other business systems, supports automation, large-scale personalization, and omnichannel strategies.	Almost no integration; creates data silos, hindering business efficiency & scalability.

Tips for Sending WhatsApp Blast Safely to Avoid Being Blocked

To ensure WhatsApp Blast delivery runs safely without the risk of blocking (anti banned), here are important tips you can apply:

1. Use Official and Trusted WhatsApp Blast Services

Make sure you use WA blast services based on the official API from a trusted WhatsApp BSP like Mekari Qontak.

This service is designed so that businesses comply with all WhatsApp policies, making it safer and more reliable.

2. Obtain Customer Consent

The next tip is to ensure that the business has obtained explicit permission (opt-in) from customers. This means customers agree to receive messages, whether through registration forms, websites, or previous interactions with the business.

Avoid using random numbers or contacts that are not relevant to your business because this can increase the risk of messages being reported as spam.

3. Manage Sending Volume and Frequency with a Tier System

A smart message delivery strategy is key to keeping customers comfortable and accounts safe. Instead of sending all messages at once, divide your sending into several stages to avoid spam.

In the WhatsApp Business API, sending volume settings are influenced by a tiering system that limits the number of unique contacts you can reach within 24 hours. There are four levels, namely as follows:

• Tier 1: Maximum send messages to 1,000 unique contacts per 24 hours.
• Tier 2: Maximum send messages to 10,000 unique contacts per 24 hours.
• Tier 3: Maximum send messages to 100,000 unique contacts per 24 hours.
• Tier 4: Unlimited unique contacts per 24 hours.

4. Create Engaging and Relevant Messages

Make sure the message content matches customer needs and interests. You must create content that is clear, informative, and useful, such as special offers and product announcements.

Try not to engage in overly aggressive promotions. Messages that are too dominated by promotions can be considered disturbing or even spam by customers

5. Use Verified Numbers

To maintain customer trust and ensure you always comply with WhatsApp rules, it is very important to use numbers that have been registered and verified as official WhatsApp Business accounts.

Verified accounts, such as those using the WA green tick or currently changed to the WA blue tick, will demonstrate professionalism and the legitimacy of your business.

This will provide assurance that customers are communicating with your business as a legitimate entity.

6. Monitor Responses and Avoid Messaging Inactive Numbers

Utilize available tracking features to monitor message performance. This allows businesses to know exactly who has received and read the messages sent.

It is also important not to continuously send messages to numbers that are inactive or do not provide a response. This will waste resources and potentially increase the risk of being flagged as a spam account.

7. Provide an Unsubscribe Option

Include an option for customers to stop receiving messages if they are no longer interested. This shows respect for customer privacy and prevents spam reports.

When customers feel they have control, they tend to have a more positive view of your brand.

8. Avoid Content That Violates WhatsApp Policies

You should not send suspicious links, false information, or content that violates WhatsApp policies. Make sure your messages are professional and aligned with business ethics.

This step ensures your WhatsApp Blast delivery runs safely, effectively, and remains compliant with WhatsApp policies.
In addition to keeping accounts active, this step also increases customer trust and experience.

9. Do Not Purchase Contact Databases to Send Blast Messages

Buying or using contact databases from unclear sources is one of the riskiest practices in sending WhatsApp Blast.

Such contact lists usually contain recipients who have not given permission (opt-in) to receive messages from your business, and may not even know or be interested in the products you offer.

This condition has a high potential to cause your messages to be reported as spam by many users. This becomes a serious warning signal for WhatsApp and the risk of your account being blocked will increase.

10. Monitor Campaign Performance Regularly

An important step after sending WhatsApp Blast messages is to monitor campaign performance regularly. Through the Campaign Detail page, you can see important data such as customer name, phone number, and message delivery status.

In addition, you can also review campaign results more comprehensively through the analytics report dashboard. Here, campaign performance is displayed in the form of metrics and visualizations such as status and total conversations, as well as agent, broadcast, and bot performance.
