To send proactive business-initiated messages outside the 24-hour Customer Care Window on WhatsApp, you must obtain opt-in consent from customers. SMSGatewayCenter makes it easy to collect and manage these opt-ins while ensuring compliance with WhatsApp’s policies. Here’s how to do it:

Understanding Opt-In Requirements #

WhatsApp requires businesses to get explicit opt-in consent before messaging customers. This ensures customers receive only useful and expected messages from businesses they want to hear from. Supported opt-in methods include:

  • SMS
  • Website forms
  • In a WhatsApp thread
  • Over the phone via Interactive Voice Response (IVR) flows
  • In person or on paper (e.g., signed physical documents)
    We recommend designing user-friendly opt-in flows to optimize the customer experience.

Adding Opt-Ins on SMSGatewayCenter #

  1. Access the Add Opt-In Page
    • Log in to your SMSGatewayCenter account at https://unify.smsgateway.center/.
    • Navigate to the Add Opt-In page under the WhatsApp Business API section in your dashboard.
  2. Enter Opt-In Details
    • Select your WhatsApp Business API (WABA) number from the dropdown list.
    • In the Mobile Number field, add the phone numbers of customers who have opted in. You can add single or multiple numbers, separated by commas or new lines.
    • Ensure all numbers include the country code prefix (e.g., +91 for India).
    • Click Save Changes to add the numbers to your opt-in list.

Managing Opt-Ins #

  1. Access the Manage Page
    • Go to the Manage page in the WhatsApp Business API section of your dashboard to view your opt-in clients list.
  2. Manage Your Opt-In List
    • View the status of each number (opt-in or opted out).
    • See the mobile number associated with each opt-in client.
    • Use the search field to find specific mobile numbers.
    • Delete any opt-in number if needed.
    • Manually mark a number as opted out by clicking the Thumbs Down button.

By following these steps, you can ensure compliance with WhatsApp’s opt-in policies while effectively managing your customer communications. For further assistance, contact our support team at contact @ smsgatewaycenter . com or call +912228657726.
