Mumble

Mumble is a web-based platform built around the official WhatsApp Business API, designed to help small and mid-sized businesses manage customer conversations, automate replies, and run marketing campaigns without needing WhatsApp's raw API directly. Its core features include a shared team inbox with multi-agent support so several staff can handle incoming chats from one dashboard, a no-code chatbot builder for automating common questions, and broadcast messaging for sending campaigns to opted-in contacts. Beyond messaging, Mumble includes CRM features for segmenting and tracking customers through a sales or support journey, a website tracking script that ties visitor behavior back to WhatsApp conversations, and analytics for measuring engagement across campaigns. It connects to external business tools including Make, Pipedrive, Monday.com, Zoho CRM, and Airtable, letting WhatsApp activity feed into a company's existing sales or operations workflow. The company offers custom API documentation for deeper integrations and a free trial for prospective customers. Mumble is aimed at businesses across e-commerce, real estate, finance, and hospitality that already use WhatsApp informally with customers and want to formalize it into a managed sales and support channel. Detailed pricing is not published on the main site, though the company references a separate pricing calculator based on message volume, so cost depends on usage.
