A WhatsApp marketing platform is the software a brand uses to sell over WhatsApp: it broadcasts offers to customers who have agreed to receive them, runs a chatbot that answers questions and takes orders, wins back abandoned baskets, and keeps every conversation in one shared inbox. It is also called a WhatsApp Business platform or a conversational commerce platform. Most of these platforms were started in India, for Indian brands and small businesses.
Why WhatsApp? In India, many customers ignore email but read every WhatsApp message. A brand cannot use the ordinary WhatsApp app to message thousands of people. Instead, it must use the WhatsApp Business API, which Meta opened to companies. Through it, a company's own software can send and receive WhatsApp messages automatically. The marketing platform is the screen on which the brand's staff use it, without writing any code.
WhatsApp sets strict rules. A brand may message only customers who have opted in, meaning they agreed to hear from it, for example by ticking a box at checkout. A message that the brand starts must use a template that Meta has approved, and Meta charges the brand a small fee for each one. When a customer writes to the brand, the brand may reply in its own words, without a template, for 24 hours. If many customers block or report a template message, Meta pauses that template for a few hours. If this happens a third time, Meta disables the template. If the brand keeps sending templates that customers block, Meta can also restrict the brand's phone number.
Consider a block-print clothing brand from Jaipur that sells only online. It has 18,000 customers who opted in. Before Teej, it broadcasts its new collection to all of them, with photos and a link. Later that week, a shopper leaves a ₹1,850 kurta set in the basket of the brand's online store. The store tells the platform. Thirty minutes later, she receives a WhatsApp message with a picture of the kurta set and a link back to her basket. She replies: "Is this available in XL?" The chatbot checks the catalogue and answers yes. It sends her a UPI payment link, and she pays inside the chat. When another customer asks about a damaged parcel, the chatbot cannot help. So the chat appears in the shared inbox, where an employee in the support team answers it.
Newer chatbots are run by an AI model. They recommend a product, answer questions about size and fabric, and complete the order with no person involved. Selling through the conversation itself is called conversational commerce. Complicated complaints are often passed on to help desk software.
The platform sends its messages through the WhatsApp Business API. Some platforms are Meta's approved partners and connect to the API themselves. Others send through a messaging company that is a Meta partner. If a customer is not on WhatsApp, the platform can send an SMS instead, through an A2P SMS aggregator.
