A bulk application is a software used to send messages to multiple contacts simultaneously. Bulk WhatsApp is one of the features of the WhatsApp API with the function of mass messaging. The bulk application makes it easier for businesses, one of which is for customers to receive personalized messages.

Bulk message is a service that sends instant messages in large quantities to many contacts at once. That’s why this service is widely used by businesses to support marketing activities and prevent fraud.

Using an unofficial WA bulk sender can be highly dangerous. This is because these types of applications are typically created by third-party developers, rather than by WhatsApp. As a result, you may face several risks such as possibility of your device being blocked by WhatsApp and increase the vulnerability to hacking.

To avoid these potential risks, it is recommended to use official WhatsApp bulk or WhatsApp blast services offered by a WhatsApp API Official Business Partner or a WhatsApp Business Solution Partner. One such provider is Mekari Qontak.
