Best Practices

Do's

  • Use specific labels and search queries to limit results
  • Set appropriate maxResults to avoid processing too many emails
  • Combine with For Each node to process emails individually
  • Use Gmail search operators for precise filtering
  • Check the Success field before processing emails
  • Store processed email IDs to avoid duplicate processing

Don'ts

  • Don't retrieve thousands of emails at once
  • Avoid running this node too frequently (respect rate limits)
  • Don't forget to handle the Error field
  • Avoid searching without any filters (retrieves too many emails)
  • Don't process sensitive data without proper security measures
  • Avoid hardcoding search queries (use template variables)
💡
Pro Tip: Use Gmail's advanced search operators like 'is:unread', 'after:YYYY/MM/DD', 'has:attachment', 'from:', 'subject:' to precisely filter emails. Combine multiple operators with spaces for powerful queries.

Troubleshooting

Common Issues

No Emails Returned

Symptoms: Node succeeds but returns empty array

Solution: Check that your search query or label actually has matching emails. Test your search query in Gmail's web interface first to verify it returns results.

Permission Errors

Symptoms: Node fails with insufficient permissions

Solution: Ensure the Gmail read scope is granted in your Google account connection. You may need to reconnect your Google account with the proper scopes.

Rate Limit Errors

Symptoms: Node fails intermittently with quota exceeded errors

Solution: Reduce the frequency of email checking or lower maxResults. Implement delays between runs and consider caching results.

Incomplete Email Content

Symptoms: Email bodies are truncated or missing

Solution: This is normal for very long emails. Gmail API may limit content length. For full content, consider using the Gmail web interface or increasing API quotas.
