AI Inbox Reply Automation for La Growth Machine (n8n + OpenAI)

Automatically Reply to La Growth Machine Inbox Messages with OpenAI (n8n + GPT-4o)

• Filters to only proceed for inbound messages (messages received from the lead), avoiding replies to outbound events.
• Applies steering context by adding the campaign objective, product context, and tone guidelines to guide the generated response.
• Generates a reply with OpenAI by sending the lead details plus recent conversation history so the response stays consistent with the thread.
• Sends the generated message back to the lead via La Growth Machine as a LinkedIn message.
