Auto-Label Gmail Messages with Custom Categories Using GPT-4 Mini

**Why settle for Gmail's default tabs when AI can sort your inbox your way?** ### Who is this for? Job seekers, freelancers, and students who receive job-related emails and want them auto-sorted into labels. ### Use case - **Problem**: Job emails get buried. Manually reading, labeling, and tracking them in a sheet is error-prone and time-consuming. - **Use Case**: An n8n workflow that fetches new Gmail messages on a schedule, classifies them with OpenAI, and adds customized Gmail labels defined by the user. ### What this workflow does? 1. Runs on a **schedule (Cron)** to fetch new Gmail messages. 2. Uses OpenAI to classify each email into: **Job Opportunity, Application Status, Enquiries, or Others** (you can edit categories). 3. **Adds Gmail labels** accordingly (auto-creates them if missing). ### Prerequisites - n8n (Cloud or self-hosted). - Credentials set up in n8n: - Gmail OAuth - OpenAI (API key) ### Setup - Import the **JSON** (below) into n8n. - Open **Credentials** for Gmail, OpenAI. - In the **OpenAI node**, pick your model (e.g., gpt-4o-mini or any GPT-4 class model). - In the Gmail Add Labels nodes, confirm/adjust label names: - **Job Opportunity**, **Application Status, Enquiries, Others** ### How to customize it for your needs - Add a Follow-Up Date parser (e.g., “We'll get back in 2 weeks”) — push to Calendar. - Extend categories (e.g., **Interview Invite, Offer, Rejection, HR Enquiry**). - Threaded Gmail Draft Reply for Enquiries using a template. ### Troubleshooting - **No items flowing?** Check Gmail scope/label filters and Cron timing. - **Labels not created?** The Gmail node can create them; ensure the label names match exactly. ### Why Use This Template? Gmail can classify messages into Spam, Promotions, or Social, but have you ever wished you could sort emails **your own way**? With this AI-powered workflow, you can create **custom categories** that fit your needs - like **Job Opportunity, Application Status, or Enquiries** - so you never lose track of what matters. ### Need Assistance?
