What if your AI sales agent could follow up with leads across WhatsApp, SMS, email, and more—without ever losing context?
In this video, I'll show you how to build a complete multi-channel AI sales agent in n8n that maintains conversation memory no matter which platform your leads use. You'll learn how to set up a custom CRM in Airtable, unify incoming messages from different channels, and use a single lead ID to track conversations across platforms.
I'll walk through the entire automation step-by-step: setting up Twilio for WhatsApp and SMS, creating a code module that standardizes inputs, configuring Postgres chat memory in Supabase, and building an AI agent that collects lead information before answering product questions. By the end, you'll have a 24/7 sales system that works seamlessly across every channel.
