Automated Email Classification & AI Response with Gmail, GPT & Sheets

This n8n workflow automates the processing of incoming Gmail emails by classifying them into categories such as Support, Sales, Complaints, Information, or Other using OpenAI's GPT. For Support and Sales emails, it generates intelligent draft responses and applies appropriate labels in Gmail. Other categories receive targeted labels without drafts, ensuring streamlined organization.

All processed emails, classifications, and generated drafts are logged in a Google Sheets 'Logs' sheet for easy tracking and auditing. Errors are automatically captured in an 'Errors' sheet with details like node, message, time, and IDs, allowing for robust debugging and workflow reliability even with multiple emails.

Benefits include massive time savings on email triage, consistent response quality via AI, and centralized logging for compliance and analysis. Use cases span customer support (quick replies), sales (lead nurturing), HR (inquiry handling), and general inbox management, reducing manual effort by 80-90% for high-volume inboxes.
