How we write these guidesIf you use the WhatsApp Business API, you cannot just message anyone whatever you like. To start a conversation, or to reach someone after a day of silence, you use a message template: a pre-written, pre-approved message. Templates are the backbone of business messaging on WhatsApp, and once you understand them, most of the platform's rules click into place.
The quick answer: a template is a message format you submit to Meta for approval before you can send it. Templates come in three categories (marketing, utility, and authentication), and the category determines what you are allowed to say and what it costs.
Why templates exist
WhatsApp is protective of its users. To stop businesses from spamming people, Meta says that any message that starts a conversation, or reaches someone outside the 24-hour customer service window, has to follow an approved template. This keeps quality high and is the reason WhatsApp still feels clean compared to email or SMS.
Inside the 24-hour window (the period after a customer messages you), you can reply with normal free-form messages. Templates are for outside that window, or for making first contact.
The three template categories
Utility templates support an action or request the customer already made. Order confirmations, shipping updates, appointment reminders, payment receipts. These tend to be welcomed because they are useful and expected.
Authentication templates deliver one-time passcodes and login verification. Short, functional, security-related.
Marketing templates are everything promotional: offers, launches, re-engagement, newsletters. They have the most rules and the highest cost, because they are the most intrusive if misused. They are also where a lot of revenue comes from when done well.
Getting the category right matters, because Meta assigns and reviews categories, and the category drives both approval and price.
Approval: what gets a template rejected
Templates are reviewed before they go live, usually quickly. Common reasons for rejection: pushy or misleading wording, placeholder mistakes (the variables like {{1}} not set up correctly), promotional content labeled as utility, or formatting problems. The fix is almost always clearer, more honest wording and the correct category. A good provider handles submissions and resubmissions for you.
When templates cost money
Since July 2025, Meta has charged per delivered message, and only for messages a business sends. The category and the customer's country set the rate. The messages your customers send you are free. Marketing, utility, and authentication templates are all charged. Since October 1, 2026, that includes utility templates sent inside an open 24-hour window, which used to be free. Your free-form replies inside the window are service messages, and Meta has charged for them since the same date. Each business phone number gets 1,000 free service messages a month, and Meta charges starting with the 1,001st. When a customer writes to you from a Click-to-WhatsApp ad in the WhatsApp Android or iOS app and you reply, Meta opens a free entry point window that can stay open for up to 7 days. While it is open, Meta does not charge for marketing, utility, authentication, or service messages. We break this down with examples in the pricing guide.
A practical way to think about it
Use the 24-hour window for real conversations and support. Replies there need no template, and each business phone number gets 1,000 of them free each month. Use utility templates to keep customers informed about things they are already doing with you. Use marketing templates deliberately, for offers worth interrupting someone over, with clear opt-in. That mix keeps your quality rating healthy and your costs sensible.
