AI Multi-Agent Inbound Router (Sales, Support and HR)

Description:

An automation that handles every message arriving through a website contact form, with no manual sorting. An AI classifier reads each message and sends it to the right specialist agent:

Sales agent: logs the lead in Google Sheets and emails a personalized reply that proposes a call or demo.

Support agent: sends an empathetic, practical reply and promises a 24-hour follow-up.

HR agent: forwards an internal summary to the HR team and confirms receipt to the applicant.

There’s also a smart upsell step. After a support case, a second AI check decides whether the customer is calm and the issue suggests a real upgrade need. If so, the workflow waits and sends a gentle, non-pushy upsell email. Angry customers, refunds, and billing disputes are deliberately skipped. Replies come back in the customer’s own language.

Built with: n8n, Google Gemini, OpenRouter, Gmail, Google Sheets, AI agents with tool calling, text classification.
