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.
