Description

📧 AI-Powered Gmail Auto-Labeling with Smart Classification

This n8n workflow automatically organizes your Gmail inbox by intelligently categorizing incoming emails and applying custom labels using AI-powered sentiment analysis. Say goodbye to manual email sorting and hello to an organized inbox!

Use Cases

• Business Email Management: Automatically sort partnership inquiries, meeting requests, and promotional emails
• Sales Team Automation: Identify and label cold outreach and high-priority leads
• Executive Assistants: Filter important meetings and urgent matters for busy professionals
• Marketing Teams: Separate promotional content from genuine business communications

Good to Know

• The workflow runs every minute to check for new emails
• Each email is processed only once - already labeled emails are automatically skipped
• Uses OpenAI’s GPT model for accurate email classification (API costs apply)
• Processes emails in batches to handle multiple incoming messages efficiently

How It Works

1. Gmail Trigger continuously monitors your inbox for new emails every minute
2. Switch Node checks if emails already have labels (Other, Promotion, or Meeting) to avoid duplicate processing
3. Loop Node processes emails in batches for efficient handling
4. AI Classification analyzes the email’s sender, subject, and content using OpenAI’s GPT model to categorize into:
   • Partnerships - Collaboration opportunities and B2B proposals
   • Promotional - Marketing emails and newsletters
   • Cold Outreach - Unsolicited sales emails and prospecting
   • Meeting - Calendar invites and scheduling requests
   • High Priority - Urgent matters requiring immediate attention
   • Other - Everything else that doesn’t fit the above categories
5. Label Application automatically applies the appropriate Gmail label based on AI classification
6. Loop Completion returns to process the next email in the batch

How to Use

• Set up your Gmail credentials to connect the workflow to your account
• Create custom labels in Gmail (or use the pre-configured label IDs in the workflow)
• Add your OpenAI API credentials for AI classification
• Activate the workflow and let it run automatically in the background
• Optionally adjust the polling frequency from “every minute” to your preference

Requirements

• Gmail OAuth2 credentials for email access and label management
• OpenAI API key for GPT-powered email classification
• Pre-created Gmail labels for each category (or modify label IDs in the workflow)

Customizing This Workflow

• Add More Categories: Extend the sentiment analysis node with additional email categories relevant to your business
• Adjust Classification Logic: Modify the AI prompt to better match your specific email patterns
• Change Polling Frequency: Update the Gmail trigger to check more or less frequently based on your email volume
• Add Actions: Extend each label branch to trigger additional actions like Slack notifications, database updates, or auto-replies
• Filter by Sender: Add conditions to the Switch node to handle VIP senders differently
