Official vs Unofficial WhatsApp Bulk Senders: What Every Business Must Know
The right way to reach your customers — without losing your business account.
Let’s start with a real situation.
Last year, a small online store decided to send promotional messages to its customers through WhatsApp. They found a tool on the internet that promised to send thousands of messages in one go, without needing any approval or business verification.
They thought, “Why not save time and money?”
But within two days, their WhatsApp number was blocked. Suddenly, they couldn’t reply to their customers. No more order confirmations. No updates. No chats.
Just like that, their business went silent. Customers got frustrated. Some even asked for refunds. And it all happened because they chose the wrong way to send bulk messages.
Now you might be wondering — how did this happen? Let’s break it down.
“It’s not just the message that got blocked — the business’s connection to customers was gone.”
What is WhatsApp Bulk Messaging?

Bulk messaging on WhatsApp means sending one message to many people at the same time. It’s not like a group chat. Each person receives the message individually. So it feels personal.
Businesses use it to:
- Tell customers about new offers or discounts
- Send updates about orders or deliveries
- Remind people of appointments
- Ask for feedback or reviews
- List Reconnect with customers who haven’t replied in a while
Because people check WhatsApp so often, messages here are usually read within minutes. That’s why businesses love it.
But here’s the thing — how you send those messages really matters.
The Two Ways to Send Bulk WhatsApp Messages
