WhatsApp marketing for business: strategy, examples and what it costs

WhatsApp marketing works when people have asked to hear from you and you answer fast. Meta's rules require opt-in, charge per delivered template message on the official API, and let WhatsApp limit senders who get blocked. A sound plan collects permission first, starts from conversations people begin, keeps messages short and personal, and measures replies and booked meetings instead of messages sent.

Businesses are drawn to WhatsApp because it is where customers already talk. The same fact makes it unforgiving: your message sits beside a person's family chats, and one block counts against your number. This guide covers what WhatsApp marketing is, the three ways to do it, a six step strategy, example messages, and what it costs. Statements about Meta and WhatsApp come from their own pages, read on 25 October 2026. Policies and prices change, so check the originals before you commit budget.

What counts as WhatsApp marketing?

Four activities fall under the label, and they carry very different risk:

1. Answering inquiries. A person writes first, you reply quickly. This is the safest and usually the most valuable.
2. Click to WhatsApp ads. An ad on Facebook or Instagram opens a chat with your business. The person started the conversation.
3. Messages to people who opted in. Offers, restock notices and reminders to a list of people who agreed.
4. Follow ups after another channel. A short note after a LinkedIn or email exchange where WhatsApp was agreed or is a reasonable next step.

Sending offers to a list of strangers is not on the list. WhatsApp's Business Messaging Policy says you may contact people only if they gave you their number and opt-in permission, and that users should expect the messages they receive.

Which of the three ways should you use?

Our WhatsApp Business API cost post explains the pricing model in detail. Sellinger takes the third route: you link your own WhatsApp account by scanning a QR code, and the agent sends and answers through it. WhatsApp itself limits outbound messaging, so first messages run at a small daily volume. It is a conversation tool, not a mass messaging tool.

A six step WhatsApp marketing strategy

1. Collect permission where people already are. Add a WhatsApp option to your contact form with a plain sentence: "We will message you on WhatsApp about your request." Add a click to chat button on pages where visitors ask questions. The policy asks for clear instructions on how to opt out, so say how to stop in your first message.

2. Start from inquiries, not from lists. The first target is every person who has already written to you: website forms, ad leads, Instagram and Facebook messages. Speed matters most here. Our post on qualifying inbound leads on WhatsApp shows the questions to ask.

3. Write like a person, in a few lines. One idea per message. Use the person's name and the thing they asked about. Skip banners, emoji walls and long links in the first line.

4. Use the 24 hour window. On the official API, a window opens when the person writes and lets you send free text for 24 hours. After it closes, only approved templates reach them, and those are charged. Answering inside the window is cheaper and reads better.

5. Follow up once or twice, then stop. If there is no reply, a short second message after a day or two is reasonable. After that, move on or switch channel. The multichannel sequence post shows where WhatsApp fits.

6. Respect every stop. WhatsApp's policy says you must respect requests to block or discontinue, on or off WhatsApp. Sellinger's agent stops when a contact replies with an opt out such as STOP, and the contact goes on the suppression list.

What do good WhatsApp marketing messages look like?

These are made up examples, not customer messages.

Reply to a form request (made up):

"Hi Elena, thanks for asking about the weekend package. I am Ivan from [hotel]. Two rooms are free on the 14th. Do you want me to hold one while you decide?"

Offer to an opted in customer (made up):

"Hi Elena, you asked us to tell you when the autumn menu starts. It starts Friday. Reply YES and I will send the menu, or STOP and I will not write again."

Follow up after LinkedIn, once agreed (made up):

"Hi Marco, as agreed on LinkedIn, here is the one page overview. Questions are welcome here."

What they share: a true reason, a name, one clear next step and a way out. None pushes a link in the first line.

What does WhatsApp marketing cost?

On the official API, Meta's pricing page says it charges per delivered message, as of 1 July 2025, and that rates depend on the message category and the recipient country. The page lists marketing, utility and authentication templates, plus service messages sent in the customer service window. It also says a free entry point window of up to 7 days applies when someone messages you from a click to WhatsApp ad. Meta says it may change prices only on the first day of a quarter, and that charging for service and utility messages inside a window began on 1 October 2026, with a free tier of 1,000 service messages per phone number a month. Check the page for current numbers before you plan a budget.

Three costs people forget:

• Provider fees. Most businesses reach the API through a provider with its own plan or markup. Ask for the fees in writing, including what happens to your number if you leave.
• Template review. New templates need approval, which slows campaigns.
• Staff time. A WhatsApp channel needs someone to take over when the conversation gets hard. Our human handoff post covers when an agent should stop.

On Sellinger there is no Meta message fee, because you connect your own account. WhatsApp is on the pricing page from $29 a month, with a 30 day free trial and no card.

How do you measure it?

Messages sent is a vanity number. Track these instead:

Read your first batch yourself. If several people answer with short, annoyed replies, fix the list or the wording before you raise volume.

What should you avoid?

• Buying lists of phone numbers. Where a number came from matters under data protection law, and WhatsApp's policy starts from permission.
• Identical text to many people, which reads as a broadcast. Our post on WhatsApp cold outreach for B2B covers the ban risk.
• Promising results. No tool can promise that a number will never be limited.

None of this is legal advice. Rules differ by country, and the policies cited above are the authority.
