Based on the issue and similar reports ([github.com]( Duplicate Outlook Emails · Issue #19602 · n8n-io/n8n · GitHub ), [community.n8n.io]( Gmail triggered multiple times for same email )), here’s what to check:
1. **Verify node connections**: Ensure only one email node is active and receiving data.
2. **Check for workflow duplicates**: Look for hidden or deactivated nodes that might still trigger emails.
3. **Inspect execution logs**: Compare timestamps to confirm if emails are sent during the same execution.
If the issue persists, try recreating the workflow or switching to a different email node (e.g., SMTP) as a temporary fix.
Let me know if this works!
