WhatsApp requires businesses to have a customer's permission before messaging them. This guide explains what opt-in means, the approved ways to collect it, and how to check opt-in status inside DoubleTick. #### What's covered * [What is WhatsApp opt-in?](#what-is-whatsapp-opt-in) * [Opt-in methods](#opt-in-methods) * [Rules and restrictions](#rules-and-restrictions) * [Check opt-in status in DoubleTick](#check-opt-in-status-in-doubletick) #### What is WhatsApp opt-in? A WhatsApp opt-in is a permission request from your business to a customer, asking for their consent to receive messages — promotional or otherwise — on WhatsApp. Businesses **can't initiate contact** with a customer unless that customer has explicitly agreed to receive messages. As per [WhatsApp's policy](https://doubletick.io/blog/whatsapp-business-policy), you must secure this consent before sending any marketing, utility, or authentication conversation outside the [24-hour window](/chat-management/start-and-manage-chats/understanding-the-24-hour-messaging-window.md). Customers must always be the ones to start a conversation with a brand first. Opt-ins can be collected both directly on WhatsApp and through external channels, such as websites, signup checkboxes, and social media ads. #### Opt-in methods WhatsApp accepts several policy-compliant ways to collect opt-in: * **Your website** : ask for opt-in during checkout, for example, whether customers want order notifications on WhatsApp. * **Custom landing page** : a page built specifically to collect WhatsApp opt-ins. * **In-app pop-up** : a pop-up inside your app highlighting the benefits of opting in. * **Click to WhatsApp ad** : ads targeting existing customers that start the opt-in process directly. * **Email** : invite your email subscribers to opt in and start receiving updates on WhatsApp. * **Phone and IVR** : offer opt-in while customers are on hold. * **SMS** : invite your SMS audience to move to WhatsApp. * **Offline methods** : promote your WhatsApp channel through receipts, gift cards, ads, QR codes, and signage. * **Within a WhatsApp conversation** : ask customers directly during an active conversation if they'd like to opt in for future messages. #### Rules and restrictions WhatsApp's policies set specific requirements for collecting opt-ins: * **Active opt-in:** the customer must actively consent, either by entering their phone number or selecting a checkbox. * **User control** **:** customers should control which phone number is used, through explicit actions like entering or editing it. * **Clear messaging** **:** the opt-in message must state exactly what the customer will receive on WhatsApp, such as shipping updates, transaction notifications, OTPs, promotions, or product news. * **Mandatory format** **:** the consent message must include language like "receive \[type-of-information] on WhatsApp at \[number]," along with the WhatsApp logo and name. * **Opt-in sources** **:** secure opt-in either directly on WhatsApp or through another channel before sending the first promotional message. * **Approved templates** : the first message in a fresh conversation must use an approved template; you can continue the conversation freely for up to 24 hours after the customer's last message, but only approved templates work beyond that. * **Opt-in during conversation** : if a customer starts a conversation, you can collect opt-in during that first interaction. * **Automated messages** : you can set up automated replies within the 24-hour window, provided there's a clear escalation path to a human agent. * **Easy opt-out** : make it just as easy for customers to opt out as it was to opt in. {% hint style="warning" %} Messaging a customer without valid opt-in is a policy violation and can affect your [account quality](/meta-business-setup/account-quality/account-quality-guide.md). {% endhint %} #### Check opt-in status in DoubleTick If a customer has opted in, you can view this in the Chat section. Select the conversation, then look in the **Details** panel on the right for the **Opt-in** option. If it shows a check mark, the customer has opted in for chat communication.
#### Key takeaways * You need a customer's explicit consent before messaging them on WhatsApp. * Opt-in can be collected on WhatsApp itself or through external channels like your website, email, or ads. * The opt-in message must clearly state what the customer will receive and include the WhatsApp name and logo. * Make opting out just as easy as opting in. * Check a customer's opt-in status anytime from the **Details** panel in the Chat section. #### FAQs **Can I message a customer without opt-in if I have their number?**\ No. Having a customer's number isn't enough — you need their explicit consent before messaging them on WhatsApp. **Where can I check if a customer has opted in?**\ Open the conversation and check the **Opt-in** field in the **Details** panel on the right. A check mark means they've opted in. **Do I need a template for the first opt-in message?**\ If the customer hasn't messaged you first, yes — the first message needs to be an approved template. See [how to start a new chat with a customer](/chat-management/start-and-manage-chats/how-to-start-a-chat-with-a-customer.md). **Can a customer opt in during an active conversation?**\ Yes. If a customer starts the conversation, you can collect opt-in during that first interaction. **What happens if I message a customer without valid opt-in?**\ It's a policy violation and can negatively affect your account quality. #### **Suggested articles** [Understanding the 24-hour conversation window](/chat-management/start-and-manage-chats/understanding-the-24-hour-messaging-window.md)\ [How to start a new chat with a customer](/chat-management/start-and-manage-chats/how-to-start-a-chat-with-a-customer.md)\ [How to block and unblock customers](/chat-management/start-and-manage-chats/how-to-block-or-unblock-customers.md)\ [Account quality guide](/meta-business-setup/account-quality/account-quality-guide.md)\ [How to manage conversations](/chat-management/start-and-manage-chats/how-to-mark-chats-as-read-or-done.md) --- # Agent Instructions This documentation is published with GitBook.
