Mumble

Keeping in touch with customers over WhatsApp, sending promotions, and running sales follow-ups from one place is the job Mumble does.

Mumble is a web-based WhatsApp communication platform for businesses, built on the WhatsApp API, that combines customer management with sales automation and chatbot-style replies.

You use it to maintain an ongoing relationship with your customers and manage contact lists.

You can advertise promotions or significant events to those lists, and plan automated sales sequences that warm up leads.

Mumble also responds to relevant customer queries, and it lets you track customer journeys, so the CRM side sits in the same interface as the messaging.

The category fit is broad.

Mumble touches AI CRM, AI customer service, AI marketing and AI sales, and it sits in the no-code and low-code group, so you set up flows in a browser rather than writing code.

That makes it most useful for small and midsize teams whose customers already talk to them on WhatsApp.

If your customers mostly use other channels, a WhatsApp-only tool will cover less of your work.
