Before

Every customer message needed a manual reply — quiet conversations were lost for good.

Result

Conversations run themselves and automatically re-engage customers who go quiet.

The Problem

A business wanted to handle customer conversations on WhatsApp without a person manually replying to every message — and needed a way to re-engage customers who went quiet mid-conversation, rather than losing them silently.

The Solution

Built a WhatsApp Business API chatbot handling the core conversation flow, plus a separate automated follow-up sequence that re-engages customers who stop responding — turning a one-shot chatbot into something that actively works to bring conversations back to life.

Delivered in two milestones on Upwork: the core chatbot build, followed by an automated follow-up sequence for customer re-engagement.
