"Send bulk WhatsApp messages" means very different things depending on the tool. The Business app broadcast list is not built for real scale, and workarounds get numbers banned. Here is the right way to reach thousands of customers on WhatsApp.
Why the Business app is not real bulk
The WhatsApp Business app has broadcast lists, but they only reach people who have saved your number, and they cap at a few hundred contacts. Third party tools that promise unlimited bulk sending through the app usually break WhatsApp's terms, and Meta bans the numbers that use them. It is not a foundation to build on.
The right way: the official API
Real bulk messaging runs on the WhatsApp Business API. You send approved template messages to contacts who have opted in, from the cloud, to any number of people. Because it is the official platform, it is stable and it keeps your account in good standing.
How to send bulk messages, step by step
- Get on the API through a provider like WBIZ and connect your number.
- Build an opted-in list. Import contacts who agreed to hear from you, tagged so you can segment.
- Create and submit a template in the right category, with variables for personalisation.
- Segment the audience so each message is relevant, and preview the size.
- Schedule and send, then watch delivery and replies in your inbox.
WBIZ campaigns handle the list, the template and the sending in one place.
Staying compliant, and unbanned
- Only message opted-in contacts, and keep proof of consent.
- Send content that matches the template you got approved.
- Watch your messaging limit and quality rating, and slow down if either dips.
- Make opting out easy, and act on it at once.

Bottom line: do not fight the Business app's limits with risky tools. Send bulk WhatsApp messages on the official API, to people who opted in, and your reach stays safe as it grows.
