In France, WhatsApp boasts a penetration rate of 65%, surpassing Instagram, Snapchat, and TikTok. This figure rises to 85% among the working population, making it a preferred communication channel.
However, it is not possible to determine in advance if your customers have WhatsApp. This information becomes accessible only after sending an initial message to a contact.
Once the message is sent, META provides data called "whatsapp_valid," indicating whether the number is associated with a WhatsApp account (true or false).
The "whatsapp_valid" information can be directly viewed in WAX.
You can create segments based on the attribute "whatsapp_valid" text equal to f to easily export contacts who do not have WhatsApp.
This data is also synchronized as attributes in Klaviyo if the integration is enabled.
