It listens for new LGM messages, keeps only received inbound messages, enriches them with campaign context, drafts a response using OpenAI, and sends the reply through LGM.\n\n### Setup steps\n\n- Configure laGrowthMachine trigger credentials and select the message event that should start the workflow.\n- Set the inbound filter condition so only received messages pass through.\n- Update the campaign context fields such as campaignObjective, product, and tone in the Set node.\n- Configure OpenAI credentials and the prompt/model settings used to draft replies.\n- Configure laGrowthMachine send credentials and verify the send node maps the AI draft to the outgoing reply body.\n\n### Customization\n\nAdjust the campaign objective, product details, tone, and OpenAI prompt to match different campaigns or response styles. Add review, approval, or safety filtering before the send step if replies should not be sent automatically."
