  • Extract project keywords from email content
  • Create dynamic label names (e.g., "Project-ProjectName")
  • Use consistent color coding for project categories
  • Apply labels to organize related emails

Best Practices

Do's

  • • Use consistent naming conventions
  • • Implement a logical color scheme
  • • Always check the success output field
  • • Handle errors gracefully
  • • Use descriptive label names
  • • Consider label hierarchy and organization

Don'ts

  • • Don't create labels in rapid succession
  • • Avoid overly long label names
  • • Don't ignore API rate limits
  • • Avoid creating duplicate labels
  • • Don't use special characters in names

💡
Pro Tip: Create a label naming convention document for your team to ensure consistency across all automated workflows. This makes it easier to find and manage labels later.

Troubleshooting

Common Issues

Authentication Errors

Symptoms: Node fails with permission denied errors

Solution: Ensure Google integration is properly connected and Gmail labels scope is granted

Label Already Exists

Symptoms: Node succeeds but label isn't created

Solution: Check if label exists before creating, or handle gracefully in your workflow

API Rate Limits

Symptoms: Node fails intermittently with quota exceeded errors

Solution: Implement delays between label creation operations and monitor API usage
