WhatsApp template categories explained: Marketing, Utility and Authentication

Every conversation your business starts on WhatsApp has to begin with a pre-approved template, and every template belongs to one of three categories: Marketing, Utility or Authentication. The category decides what you pay per message, how closely Meta reviews it, and what kind of consent you need. Getting it right while you draft saves you rejected submissions and surprise invoices.

This guide walks through each category, the free service messages that sit alongside them, and the mistakes we see most often when teams submit templates.

Templates versus service messages

WhatsApp treats messages differently depending on who started the conversation. When a customer messages you, a 24-hour customer service window opens. Inside it, your team can reply with free-form messages: text, images, documents, buttons, whatever the conversation needs. These service replies don't need approval and, at the time of writing, they're free.

Outside that window, or when you want to contact someone who hasn't messaged you recently, you must use an approved template. Since 1 July 2025, the WhatsApp Business Platform charges per delivered template message, replacing the earlier model of charging per 24-hour conversation. Rates depend on the template's category and the recipient's country code.

The three categories at a glance

Marketing templates

Marketing is the broadest category and usually the most expensive per message. If a template promotes a product, announces a sale, invites someone to come back, or nudges them towards a purchase, Meta treats it as marketing. That includes messages that read as informational but have a sales goal, such as “Your favourites are back in stock.”

Marketing templates need opt-in to promotional messages, and they're the messages people are most likely to block or report when they feel irrelevant. Send them to segmented audiences through broadcast campaigns rather than to your entire contact list.

Utility templates

Utility templates confirm, update or remind customers about something they've already done or asked for. The test is simple: was the message triggered by the customer's action or request, and is it about a specific order, booking, account or payment? If both answers are yes, it's likely utility.

Utility templates cost less than marketing in most markets, and a utility template sent while a customer service window is open is free. That's a good reason to send order and delivery updates promptly when a customer has just messaged you.

Authentication templates

Authentication templates deliver one-time passcodes. Meta gives them a fixed structure: a short preset message containing the code, optional security and expiry notes, and a copy-code or autofill button. You can't add links, images or promotional text. If you need to say more, send it separately.

How category affects approval

Meta reviews every template before you can use it, and it can re-categorise a template, during review or later, if the content doesn't match the category you chose. A re-categorised template is billed at its new category's rate. A few habits make approval smoother:

• Give each template one clear purpose. Adding a discount code to a delivery update turns a utility message into marketing.
• Use variables for details that change, such as names, order numbers and dates, and supply realistic sample values when you submit.
• Be specific. “Your order {{1}} has shipped” is easier to approve than “We have an update for you.”
• Match buttons to the purpose. “Track order” fits utility; “Shop now” signals marketing.

Common miscategorisation mistakes

1. Adding a promotion to a transactional message. “Your order has shipped. Use code SAVE10 on your next purchase” is marketing, however small the offer.
2. Calling a re-engagement message a reminder. “We haven't seen you in a while” isn't tied to a transaction, so it's marketing.
3. Labelling cart reminders as utility. They encourage a purchase that hasn't happened yet, which makes them marketing.
4. Assuming every survey is utility. Whether a feedback request qualifies depends on how closely it's tied to a specific transaction and whether it carries promotional content. Check Meta's current guidelines before submitting.
5. Putting extra content in authentication templates. Anything beyond the code and its preset notes doesn't fit the format.

Putting it into practice

Keep a small library of templates for each category, name them so anyone on the team can tell what they do, and review them whenever Meta updates its category guidelines. Because category drives cost, check your expected volumes against the current rates on our pricing page before a large send.

Finally, every business-initiated message needs a valid opt-in, whatever its category. Our guide to WhatsApp opt-in best practices explains how to collect it and keep records.
