4. Create Your First Workflow 🧩

🎯 Example: Automatic Sync from Gmail to Notion

1. Start Node: Gmail → “Detect New Email”
2. Processing Node: Set → Extract email subject, body, sender
3. Target Node: Notion → “Create Page” (insert into Notion database)

> 🎨 Visual Flow: > > Gmail → Set → Notion >

✅ Configuration Example (Gmail → Notion)

• Gmail: “Detect New Email” → Condition: “From = client@company.com”
• Set Node:
  • title: ={{ $json.subject }}
  • content: ={{ $json.body }}
  • status: New Request
• Notion:
  • Database: Request List
  • Field Mapping: Title, Content, Status

👉 Result: Every time a request email arrives in Gmail, it’s automatically registered in Notion! 📩✅

5. Common App Integrations 🔄

> 💡 Pro Tip: Use the Webhook node to connect with external APIs!
> Example: When a website visitor arrives → n8n → Automatically log in Google Analytics

6. Advanced Features 🚀

✅ Conditional Branching (if-else)

• Example: If the email subject contains “Urgent”, send a warning alert to Slack
• Node: IF → Condition: {{ $json.subject.includes("Urgent") }}

✅ Loop Processing

• Example: Process multiple customer data entries at once
• Node: Set → Loop → Insert repeatedly into Notion

✅ Error Handling

• Use the Catch node to send automatic notifications when errors occur
• Example: If Notion connection fails → Send “Error occurred!” to Slack

> 🛠️ Check error logs via Execution History

7. Real-World Use Cases 🎯

🌟 Example 1: Automatic Blog Posting

• Flow:
  Notion → Templating → Tistory → Publish

• Setup:

  • Extract only documents with Publish Status = Yes from Notion
  • Format title/body using a template
  • Automatically post via Tistory API

> 🖼️ Result: Write → Auto-publish → Zero manual work 😎

🌟 Example 2: Automatic Customer Inquiry Categorization

• Flow:
  Gmail → AI Analysis → Conditional Branch → Trello or Slack

• Setup:

  • Analyze email content using OpenAI → classify as “Urgent”, “Normal”, or “Other”
  • Urgent → Send warning alert to Slack + create Trello card
  • Normal → Automatically register in Trello

> 🤖 Combining with AI boosts work efficiency by up to 3x!

🌟 Example 3: Daily Morning Report Generation

• Flow:
  Google Sheets → Template → Gmail → Send Email

• Setup:

  • Extract yesterday’s data from Sheets
  • Format using an HTML template
  • Automatically send via Gmail (Subject: “Daily Sales Report”)
