There are so many reasons why the message which you have broadcasted is not successful delivered. Before we go into the details, let’s see what really happens behind the scene.
The blasting flows of messages begin with the thousands of sim card installed on the supplier main server. This supplier main server is connected to the WhatsApp / Telegram / LINE / Signal / Zalo server in 1 way flow of data. It means that the supplier server will flow the data of the campaign you want to send out to the WhatsApp / Telegram / LINE / Signal / Zalo server. Once the broadcast messages are successfully sent to WhatsApp / Telegram / LINE / Signal / Zalo server, a deliverability report will be generated by supplier main server. The report will show which of the successful broadcast messages have sent out successfully from supplier main server and which have failed.
Some recipients, did not receive the broadcast messages are because of the sim cards which installed in the supplier main server have been blocked by WhatsApp / Telegram / LINE / Signal / Zalo. The reason why sim cards are blocked are because of:
- Content of the messages is one of the WhatsApp prohibited content WhatsApp / Telegram / LINE / Signal / Zalo has algorithm that is the recipients did not save the contact number which we are using to send out the messages. This result into the WhatsApp / Telegram / LINE / Signal / Zalo response about the blocking alert to the specific number and reported as spam.
- Before WhatsApp / Telegram / LINE / Signal / Zalo sends out your message to your recipient & it detects that the recipients did not save the contact number, this situation is marked as “Suspicious” by WhatsApp / Telegram / LINE / Signal / Zalo. If the recipients report as “Report as spam”, then the sim card will get blocked.
- The file size or the size of the attachment is too big. It takes longer time to upload for every number.
- The banning algorithm on the WhatsApp / Telegram / LINE / Signal / Zalo server side
- Recipient sets its privacy from public to private on the app. This action prevents your message from reaching to your targeted recipients.
- Implied nakedness
- Implied sexual actions
- Magnified sexual images
Solution
There are 2 solutions to this problem.
One of the ways to increase the chance of all recipients receiving your message is by broadcasting your messages several times. Yes, some recipients may receive the same content more than 1 time.
However, this method is the best way to increase the chance of all recipients receiving your message. All broadcast message suppliers do not have an official API from WhatsApp / Telegram / LINE / Signal / Zalo. Hence, they are not able to provide detailed information such as:
- Who has successfully received your message?
- Who reads your message?

Another solution is using the official WhatsApp Business API. Currently, a lot of WhatsApp blasting sellers are selling a conventional way of blasting out your messages. They have been using an unofficial WhatsApp API. However, Facebook introduced the official WhatsApp Business API to the public on August 2018. You can do all sorts of amazing things with this official WhatsApp Business API. Of course, there are rules which we need to follow before we can use them. For example, we need to submit the content to Facebook for approval before you can send out the message to your targeted recipients. Once Facebook approves your content, you are free to blast out your content without worrying your number will get blocked. Another best thing is you can have a dedicated WhatsApp number that you can use for blasting purposes. However, there will be charges based on the message. Here is the pricing. You can look at the 100% delivery rate package. We hope that these 2 solutions help you.
