Project: inbox agent for SMBs

We wrap up with a project that an SMB understands in a minute: an agent that receives messages, classifies them, creates drafts, requests approval, and logs what it did.

  • Design an inbox agent with n8n and LangGraph.
  • Separate classification, drafting, approval, and execution.
  • Leave an MVP ready to implement with email, CRM, or a local folder.
