Who's it for
Customer support teams, sales representatives, and international business professionals who need to handle multilingual email communication efficiently while maintaining quality control through human approval.
How it works
This workflow automates email responses by:
- Monitoring Gmail for emails with a specific label (e.g., "To_Process")
- Translating the email content using DeepL to your preferred language
- Generating an AI-powered summary and draft reply using OpenAI
- Requesting approval via Slack with a summary and one-click approval link
- Sending the reply only after human approval is received
- Removing the label to prevent reprocessing
Set up steps
Setup takes approximately 15-20 minutes:
- Configure credentials for Gmail, DeepL, OpenAI, and Slack
- Create a Gmail label for emails to process
- Update the Slack channel ID in the configuration node
- Ensure n8n is accessible via webhook (tunnel or production mode required)
Requirements
- Gmail account with OAuth2 authentication
- DeepL API key (free tier available)
- OpenAI API key
- Slack workspace with OAuth2 app configured
- n8n instance accessible via webhook URL
How to customize the workflow
- Change translation language: Modify the DeepL node's target language
- Adjust AI model: Switch between GPT-4 or GPT-3.5 in the OpenAI node
- Customize approval message: Edit the Slack message format
- Add multiple languages: Duplicate the translation node for multi-language support
- Filter specific senders: Add conditions to process only certain email addresses
