Automated Gmail classification and labeling with GPT-4, Sheets and Slack alerts

This n8n template automates email labeling using AI-enhanced classification and intelligent routing

Gmail users report spending significant time manually sorting email, so this tool helps alleviate that burden.

How it works - Gmail Trigger monitors unread emails every 2 minutes - Once an email arrives, the content is extracted with HTML cleaning - AI Agent (the node is set for Chat GPT-4) is used for classification & entity extraction - A Structured Output Parser parses the email to JSON - A 9-way category routing system categorizes the email (Inquiry, Support, Newsletter, Marketing, Personal, Urgent, Spam, Invoice, Meeting) - Gmail auto-labeling is used for each category - Google Sheets is used for logging (the main log that includes all emails and  an error log which are emails that cannot be classified) - Slack alerts are generated for high-priority/urgent emails - Error handling is done with separate error logging in Google Sheets

How to use - Set up credentials for Google Gmail, LLM (ChatGPT, Gemini, etc.), Google Sheets, and Slack - Modify the categories as needed per user preference

Requirements - Gmail  - Any LLM like ChatGPT or Google Gemini - Google Drive with Google Sheets is optional for logging and error handling - Slack is optional for high-priority messages
