Overview of the solutions for your WhatsApp marketing

WAX: the conversational commerce expert powered by AI

WAX (WhatsApp Experience) is no longer just an automation tool, it is a true sales agent supercharged by artificial intelligence.

  • Conversational AI & Tone of Voice: WAX features an AI capable of answering your customers' recurring questions while adapting perfectly to your editorial guidelines. Whether you are formal or casual, the AI stays consistent.
  • AI-assisted shopping: The tool can analyze customer requests ("I'm looking for a blue dress for a wedding") and automatically suggest the most relevant items from your catalog.
  • Engagement: Use of rich formats (carousels, buttons) combined with 24/7 responsiveness thanks to AI.

Klaviyo: the omnichannel orchestrator

Klaviyo treats WhatsApp as an extension of its email segmentation power.

  • Outstanding data analysis: Klaviyo is unbeatable on reporting. Its ability to attribute every euro of revenue to a specific action (an email click, an SMS view, a WhatsApp interaction) is the most advanced on the market.
  • The king of multichannel: Klaviyo orchestrates your entire ecosystem, based on each customer's habits, thereby avoiding saturation.
  • Predictive segmentation: Thanks to years of e-commerce data, its AI predicts certain attributes even when they are not filled in, along with the likely date of the next purchase to trigger the right message at the perfect moment.

FAQ on WhatsApp marketing solutions
