# WhatsApp marketing for ecommerce: a practical guide > Online stores market on WhatsApp by sending Meta-approved template messages to customers who opted in. Since July 1, 2025, Meta charges per delivered template message by category and country, and it limits how often each person receives marketing, so the best results come from fewer, well-targeted messages. Canonical: https://tellnod.com/guides/whatsapp-marketing-for-ecommerce Last updated: 2026-10-22 Author: Tellnod team ## Business app or API: choosing a WhatsApp route WhatsApp offers two routes for businesses, and the right one depends on how many customers you message and how. The **WhatsApp Business app** runs on a phone. Its classic broadcast lists hold up to 256 contacts each and reach only people who saved your number in their phone [S8]. The app also offers business broadcasts with scheduling, buttons and read insights [S9]. For a shop with a few hundred loyal customers, this can be enough. The **WhatsApp Business Platform** (often called the WhatsApp Business API) is for sending at scale through software. Messages that start a conversation must use templates Meta has approved [S2], each delivered template is charged [S1], and sending capacity grows as your account proves it sends wanted messages [S6]. Most marketing tools use the Platform, and Tellnod’s WhatsApp support, which takes early-access requests, is designed for it too. | Point | Business app | Platform (API) | | --- | --- | --- | | Where you send from | A phone | Software connected to Meta | | Reach per send | 256 contacts per broadcast list | Starts at 250 unique people a day, rising with good quality | | Who receives | People who saved your number | People who opted in | | Message format | Free-form | Approved templates outside the 24-hour window | | Cost | The app is free to use | Per delivered template message | ## Opt-in requirements Meta’s WhatsApp Business Messaging Policy allows you to contact people only if they gave you their number and agreed to receive messages from you [S2]. Meta’s opt-in guidance adds that the request must clearly state the person is opting in to communication from your business and name the business [S3]. You are responsible for meeting local consent law as well [S2]. Opt-in can be collected on your website, at checkout, by SMS, by phone or on paper [S3]. For an online store, the common places are a checkbox at checkout and a field in the sign-up form. Write the checkbox so it names your shop and the channel, for example: “Send me order updates and offers from Ninefold on WhatsApp.” - Do not treat an email subscription as WhatsApp consent. Ask separately. - Keep a [consent record](https://tellnod.com/glossary#consent-record) for each number: where, when and the words shown. - Consider separate opt-ins for order updates and for marketing. Meta suggests this can reduce blocks [S3]. - Honor every request to stop, whether it comes on WhatsApp or anywhere else [S2]. For the email side of consent, see [how to grow an email list for an online store](https://tellnod.com/guides/grow-email-list-for-online-store). ## Marketing template messages A template is a message format you submit to Meta before sending. Every template has one of three categories: marketing, utility or authentication [S5]. The category sets the price and the rules. - **Marketing**: promotions, launches, offers, retargeting and anything mixed or unclear. Meta treats retargeting as marketing even when the customer asked for it [S4]. - **Utility**: non-promotional follow-ups to something the customer did, such as an order confirmation, a shipping notice with tracking, a backorder notice or a refund confirmation [S4]. - **Authentication**: one-time passcodes only [S4]. Templates are reviewed automatically when you create or edit them, and only an approved template can be sent [S5]. Templates can include a media header, such as a product image, and buttons. Keep each template to one idea with one clear button. A shipping notice that also pushes a discount will be classed as marketing [S4]. ## How WhatsApp pricing works since July 2025 Since July 1, 2025, Meta charges per message instead of per conversation [S1]. You pay only for template messages that are delivered, and the rate depends on the template category and the recipient’s country code [S1]. Utility and authentication messages get lower rates at higher monthly volumes; marketing does not [S1]. - Marketing, utility and authentication templates are charged per delivered message [S1]. - Free-form replies inside the 24-hour customer service window, which opens when a customer writes to you [S10], are service messages. Each business number gets 1,000 free service messages a month; from October 1, 2026, Meta charges beyond that [S1]. - Also from October 1, 2026, utility templates sent inside an open customer service window are charged; they were free before [S1]. - Meta can change rates only on day one of a quarter, with at least a month’s notice [S1]. > Budget per country. A list split between Indonesia and the UK costs very different amounts per message. For current rates by country, see [WhatsApp Business API pricing](https://tellnod.com/guides/whatsapp-business-api-pricing). ## Use cases for an online store WhatsApp suits short messages a customer would want on their phone. The category decides cost and rules, so plan each message with its category in mind. Examples for Ninefold, a small apparel brand: | Message | Category | Notes | | --- | --- | --- | | Order confirmed, with order number | Utility | No offers or upsells in the text [S4] | | Shipped, with tracking link | Utility | Keep it purely informational | | The long coat is back in your size | Marketing | A restock alert encourages a purchase, so expect marketing | | Autumn edit launch for VIPs | Marketing | Send to a small engaged segment | | Last day of the sale | Marketing | Only to people who showed interest | Restock alerts are one of the most useful WhatsApp messages for a clothing shop: the customer asked to hear, the message is short, and the button goes straight to the product. Email remains the better place for lookbooks, size guides and anything long; the [back-in-stock email template](https://tellnod.com/templates/back-in-stock) covers the email version. ## Frequency, quality rating and sending limits WhatsApp watches how people react to your messages, and the reactions shape what you can send. - **Quality.** Meta scores message quality from how recipients treated your messages over the past seven days, using signals such as blocks, reports, mutes and archives [S10]. - **Messaging limits.** A new business portfolio can message 250 unique people outside a customer service window in a rolling 24 hours. The limit rises to 2,000, then 10,000, 100,000 and unlimited as you verify your business and send high-quality messages [S6]. - **Per-user marketing limits.** WhatsApp may hold back a marketing template from someone who rarely reads marketing or has a full inbox. Wait at least 24 hours before resending to that person [S7]. - **US numbers.** WhatsApp does not currently deliver marketing templates to US phone numbers [S7]. In practice: send marketing less often than you would by email, target people who engaged recently, make opting out obvious, and stop sending to anyone who asks.

The WhatsApp Business app is free to use for small broadcasts. On the WhatsApp Business Platform, Meta charges for each delivered template message, with rates set by category and the recipient’s country. ### Can I send WhatsApp marketing to my email list? Only to people who also opted in to messages on WhatsApp. Meta requires opt-in that names your business, so ask for WhatsApp consent separately and keep a record of it. ### What is a WhatsApp business broadcast? In the WhatsApp Business app, a broadcast sends one message as private chats to many contacts at once. Classic broadcast lists hold up to 256 contacts who saved your number. At larger scale, businesses use template messages on the Business Platform. ### Is an order update a marketing message? Not if it is purely informational. Order confirmations and shipping notices are utility templates. Adding an offer or upsell makes them marketing. ### How often can I send WhatsApp marketing messages? There is no fixed number, but WhatsApp may hold back marketing from people who rarely read it, and blocks and reports lower your quality rating. Send less often than email and only to engaged customers. ## Sources - [S1] Meta for Developers: Pricing on the WhatsApp Business Platform: (checked 2026-10-22) - [S2] WhatsApp Business Messaging Policy: (checked 2026-10-22) - [S3] Meta for Developers: Get opt-in for WhatsApp: (checked 2026-10-22) - [S4] Meta for Developers: Template categorization: (checked 2026-10-22) - [S5] Meta for Developers: Templates overview: (checked 2026-10-22) - [S6] Meta for Developers: Messaging limits: (checked 2026-10-22) - [S7] Meta for Developers: Per-user marketing template message limits: (checked 2026-10-22) - [S8] WhatsApp Help Center: How to use broadcast lists: (checked 2026-10-22) - [S9] WhatsApp for Business: Turn your contacts into conversations with business broadcasts: (checked 2026-10-22) - [S10] Meta for Developers: Service messages: (checked 2026-10-22)
