What Are WhatsApp Templates and When Do You Need Them?

The 24-Hour Free Messaging Window

Here's something important to know about WhatsApp Business: when someone sends you a message, you have 24 hours to reply for free. Think of it like a conversation window that opens every time your customer reaches out to you.

Let's say a customer messages you on Sunday morning asking about your services. You can reply anytime until Monday morning without any charges. If they message you again on Sunday evening, the clock resets—you now have until Monday evening to respond for free. Every time they send you a message, you get a fresh 24-hour window.

What's Free and What's Not?

The good news is that most of your WhatsApp conversations won't cost you anything. Here's what's completely free:

Receiving messages is always free. Your customers can send you as many messages as they want, and you'll never pay a cent for receiving them. There's no limit—whether it's 10 messages or 10,000 messages a day.

Replying within 24 hours is free. As long as you respond within that 24-hour window, you can have back-and-forth conversations with your customers without any charges from WhatsApp.

Manual conversations are free. If you're personally chatting with customers (not using your bot's AI), these conversations don't use any AI tokens in the Boti system. It's just you and your customer talking—completely free.

The only time you pay is when you want to start a conversation with a customer outside that 24-hour window. Maybe you want to send a promotional message, remind someone about an appointment, or follow up on an order. That's when you need WhatsApp templates.

What Are WhatsApp Templates?

Templates are pre-written messages that Facebook reviews and approves before you can send them. You write the message once, submit it for approval, and then you can use it whenever you need to reach out to customers first.

Why does Facebook review these messages? There are two main reasons. First, they want to make sure you're using WhatsApp responsibly—no spam, no misleading messages, nothing that violates their guidelines. Second, they need to know what category your message falls into because that determines how much you'll pay.

How Much Do Templates Cost?

When you send a template message outside the 24-hour window, WhatsApp charges a small fee. These fees go directly to Facebook, not to Boti.

Marketing messages cost about 10 cents per message. These are promotional messages like "Check out our new sale!" or "Come visit our store this weekend."

Service messages cost about 2 cents per message. These are updates about something your customer already requested—like "Your package has shipped" or "Your appointment is confirmed for tomorrow."

The difference is significant, so it's worth learning how to write your templates as service messages when possible.

Getting Your Templates Approved

Once you create a template, Facebook needs to review it. Most templates get approved within a minute, but sometimes it can take up to 24 hours. If you don't see approval right away, check back after an hour or so.

The approval process is usually straightforward if you follow the guidelines. Write clear, honest messages that provide value to your customers, and you should be fine. We have a complete guide on how to write templates that get approved quickly.

When Should You Use Templates?

Templates are perfect for situations where you need to reach out to customers first. Here are some common examples:

Appointment reminders keep your schedule full. Send a message the day before: "Hi Sarah, this is a reminder about your appointment tomorrow at 2 PM."

Order updates keep customers informed. Let them know when their package ships, when it's out for delivery, or if there are any delays.

Event invitations help you get responses. Send personalized invites to your guest list and track who's coming.

Follow-ups help you close more sales. Reach out to leads who showed interest but didn't purchase yet.

Promotions drive more business. Announce new products, sales, or special offers to your customer list.

The key is that you're starting the conversation, not responding to one. If your customer messages you first, you don't need a template—you can just reply normally within your 24-hour window.
