Overview
What is bulk WhatsApp marketing?
Bulk WhatsApp marketing means sending the same or a personalised WhatsApp message to a large list of customers who have opted in to receive it. It runs on the WhatsApp Business API, which is built for businesses that need to message at scale, rather than on the free WhatsApp Business app.
Short answer: You can send WhatsApp marketing messages to many people at once through the WhatsApp Business API, using message templates that WhatsApp has approved. Customers must have opted in first.
WhatsApp Business app and WhatsApp Business API
The free WhatsApp Business app suits a small shop answering chats by hand. Its broadcast lists are limited in size and reach only people who saved your number. The API has no such limit on audience size, supports approved templates, buttons and automation, and connects to a panel where your team runs campaigns and reads reports.
Why WhatsApp works for marketing
Customers already spend time in WhatsApp, so an offer arrives next to messages from friends and family. A message can carry an image, a video, a PDF or tap-to-act buttons, and the customer can reply in the same chat.
Message types
Three kinds of WhatsApp business messages
WhatsApp sorts every business message into a category, and each category has its own approved templates. All of them go to customers who have opted in.

Offers, launches, event invitations and campaigns. This is what bulk WhatsApp marketing sends.Utility messages

The rules that keep your number safe
WhatsApp can limit or block numbers that send unwanted messages. These habits keep your account healthy.
-
Opt-in first: Message only people who have agreed to hear from you on WhatsApp. Keep a record of how and when they agreed.
-
Approved templates: Business-started messages use templates approved in advance, in the right category: marketing, utility or authentication.
-
Quality matters: WhatsApp rates your messages by how customers react. Good quality raises how many people you can message; blocks and reports lower it.
-
The 24-hour window: When a customer writes to you, you can reply freely for 24 hours. After that, a template is needed to start the conversation again.
-
Easy opt-out: Tell people how to stop receiving messages and respect it straight away.
-
Honest content: Follow WhatsApp's business policy and avoid prohibited products and misleading claims.
Which channel?
WhatsApp or SMS: which should you use?
Most businesses use both. This is how they differ.
| SMS | ||
|---|---|---|
| Who can receive it | Customers with WhatsApp and an internet connection | Any mobile phone, with no internet needed |
| Content | Text, images, video, documents and buttons | Short text with a link |
| Permission | Explicit opt-in before you message | Registered consent and DND rules apply |
| Replies | Two-way chat in the same thread | Limited; replies need a separate number or link |
| Best for | Rich campaigns, catalogues, conversations | OTPs, urgent alerts, reaching everyone |
Many businesses send the OTP by SMS and the offer on WhatsApp. We can set up both for you.

A template is a pre-approved message with fixed text and placeholders, for example a name or an order number. WhatsApp reviews each template before you can use it to start a conversation.
