Not too long ago, I stopped into a neighbourhood bakery that had just reopened after renovations. They had a good crowd, but the owner told me something surprising. He didn’t run any ads. He didn’t post anything to Instagram. All he did was send a WhatsApp broadcast to about 300 of his regulars—and just like that, people showed up.
That’s the power of WhatsApp broadcasts when used the right way.
Most small businesses are sitting on gold and don’t even realise it. If you’ve got a list of past customers or interested leads, you can use WhatsApp to keep them coming back without spending a cent on ads. It’s more personal than email, and unlike social media, your message actually gets seen. But there’s a right way and a wrong way to do it.
Let’s start with what a WhatsApp broadcast is. It’s like sending a group message, but better. When you use the broadcast feature in WhatsApp Business, each contact gets the message as if it were sent to them personally. Replies come back in a one-on-one chat. No awkward group messages. No one knows who else got it. Just direct communication, and it feels natural.
But to make broadcasts work, you need two things: permission and relevance. First, people have to save your number and you have to save theirs. That means they’ve agreed to hear from you. If they haven’t, your message won’t go through. It’s a built-in form of consent—and it helps keep things above board.
Now, let’s talk about relevance. Sending the same promo to everyone rarely works. Instead, segment your audience. This just means grouping people based on things they care about. If you run a salon, you might have one list for regulars who book every month, another for people who came in once and never returned, and maybe one for those who ask about specials.
Once you’ve got your segments, you can personalise your message. Start by using names. “Hi Amanda” always beats “Hi there.” But you can go further. Mention what they bought last time. Suggest something they might like. Say thanks for being a long-time customer. You’re not just selling—you’re starting a conversation.
One trick I’ve seen work well is what I call the double opt-in. Let’s say you partner with another local business—a florist teams up with a bakery, for example. Each one asks their customers if they’d like to receive exclusive deals from the other. If someone says yes, you add them to a separate list. Now you’re getting exposure to a whole new audience, but still with consent. It’s simple, but it works.
Of course, some businesses want more control or automation. That’s where tools like the WhatsApp Business API come in. It’s a paid service that lets you send larger volumes of messages, integrate chat into your website, and even automate replies. But for most small businesses, the regular WhatsApp Business app does just fine. It’s free, it’s fast, and it’s already on your phone.
One business owner I worked with sends out birthday discounts to his top customers each month. It’s just a quick “Happy Birthday! Here’s 15% off your next visit.” It’s not fancy, but it feels personal. And people use it.
Another runs flash sales during slow hours—“We’ve got a few slots open this afternoon. Book now and get 20% off.” That kind of message wouldn’t make sense for everyone, but because it’s sent to a specific segment (people who live nearby and tend to book last-minute), it gets results.
Here’s the thing: people don’t mind getting messages if they’re useful, relevant, and respectful. The moment it feels like spam, they’re out. But if you’re smart about it—if you take the time to personalise and send things people actually want—you’re not annoying them. You’re helping them.
And the results speak for themselves. Higher return visits. More referrals. A stronger connection with your community.
So the next time you’re sitting with your phone and thinking about how to drum up business, try this: send a short, friendly message to your top ten customers. Remind them you exist. Give them a reason to come back. Ask how they’re doing.
You don’t need a big campaign. You just need to show up where people are already talking. And today, that’s WhatsApp.
