Automate email triage with GPT-4.1-mini classification and Gmail auto-replies

How it works: - Detects new unread Gmail messages - Extracts sender name for personalized replies - Classifies the email into one of four categories - Applies the correct Gmail label and either sends an auto-reply, creates a draft, or logs the contact in Google Sheets

Setup steps: - Takes about 5–10 minutes to connect accounts and set labels - Connect Gmail, OpenAI, and optional Google Sheets in n8n - Add label IDs, Google Sheet ID, sheet name, and phone number in Set – Config - Create four Gmail labels for the categories - Keep full setup instructions in the sticky notes inside the workflow
