Auto-Label Gmail Emails with Custom AI Categories via GPT-4o-mini

This n8n workflow revolutionizes Gmail management by leveraging AI to automatically classify and label incoming emails. Triggered by a Cron schedule, it fetches new messages, analyzes their content with OpenAI's GPT-4o-mini model, and applies user-defined labels such as 'Job Opportunity', 'Application Status', 'Enquiries', or 'Others'. Labels are auto-created if they don't exist, ensuring seamless organization without manual intervention.

Ideal for job seekers, freelancers, and students drowning in job-related emails, it eliminates the tedium of manual sorting, reduces errors, and keeps critical updates visible. Customize categories easily to fit needs like 'Interview Invite', 'Offer', or 'Rejection', and extend functionality with follow-up date parsing to Google Calendar or automated draft replies.

Prerequisites include n8n setup with Gmail OAuth and OpenAI API credentials. Import the JSON, configure nodes, and adjust labels/model as needed. Troubleshooting tips cover common issues like flow blockages or label creation. This workflow delivers high ROI through time savings and enhanced productivity in email-heavy workflows.
