About using the WhatsApp Business app to communicate with your customers

Unlike WhatsApp Messenger, which is built for personal communications, the WhatsApp Business app is designed for external business communications. Each app is GDPR-compliant based on its intended purpose. If you're a small-to-medium sized business, you should use the WhatsApp Business app for business communications with your customers. The WhatsApp Business app is free to download from the Google Play store and the App Store.
