└─────────────┘    └─────────────┘    └─────────────┘    └─────────────┘
                                                                │
                         ┌─────────────┐    ┌─────────────┐    │
                         │ Send        │◀───│ Apply Label │◀───┘
                         │ Notification│    │ & Archive   │
                         └─────────────┘    └─────────────┘
```

**Configuration**:
```yaml
trigger:
  type: gmail_new_email
  filters:
    has_attachment: true
    from: ["*@company.com", "*@vendor.com"]
    subject_contains: ["invoice", "report", "contract"]

actions:
  - extract_attachments:
      file_types: [pdf, xlsx, docx, csv]
      max_size_mb: 25
  
  - upload_to_drive:
      folder_path: "/Attachments/{year}/{month}"
      naming_pattern: "{filename}_{sender}_{date}"
      create_folder_if_missing: true
  
  - organize_email:
      apply_label: "Processed/Attachments"
      mark_as_read: true
      archive: true
  
  - notify:
      channel: slack
      message: "New attachment saved: {filename} from {sender}"
```

**Best Practices**:
- Use specific sender filters to avoid processing spam
- Set file size limits to prevent storage issues
- Use date-based folder structure for easy retrieval
- Enable duplicate detection to avoid redundant uploads
