How to send bulk WhatsApp messages without getting banned

Most "ban" stories have the same shape. Someone exports a list, pastes it into a tool that drives the ordinary WhatsApp app, and sends the same message to hundreds of people who never asked for it. A few recipients report the number, and it stops working.

Volume is not the problem. Unwanted messages are. Here is how to send to thousands of people and stay in good standing.

What actually gets a number restricted?

A number is usually restricted for one of three reasons, in the order we see them cause trouble:

1. Messaging people who did not agree to hear from you. WhatsApp's policy says you may only contact people who gave you their number and confirmed they want messages from you.
2. Ignoring requests to stop. The same policy says you must honour every request to stop, including one made outside WhatsApp.
3. Using unofficial tools. Software that automates the normal WhatsApp app is not a supported way to send bulk messages, and it puts your number at risk.

Start small, then widen

A new number has no history. Start with a list of customers who know you, such as people who bought in the last 90 days or who enquired this month. Send to a few hundred, watch how many read and reply, then widen. Meta checks quality before it raises your limit, so a clean start speeds you up instead of slowing you down.

What to notice: you can choose an audience by tag and leave out any tag, so people who asked to stop never make the list.

Build the stop button into the message

End marketing templates with a clear way out, such as "Reply STOP to opt out". In Responseify, a contact who sends an opt-out word is marked as opted out and is skipped by later broadcasts, even ones you scheduled earlier. That protects you without anyone remembering to clean a spreadsheet.

A quick pre-send checklist

• Everyone on the list gave you their number and agreed to messages.
• The template is approved and says who you are in the first line.
• The message has one clear ask, not three.
• Your sending limit covers the audience.
• You have time to read the replies, because replies open a 24-hour window you want to use.
