Hi @Joe_B
I think you can achieve that by wrapping the “Send message and wait for response” node in a subworkflow,
You don’t need the loop node, since n8n handles that automatically when the Google Sheets node outputs more than one item.
Here’s an example where I send two emails and wait for the replies:
Also do not forget to disable the Wait For Sub-Workflow Completion
If this fixes the issue, please❤️ and mark the reply as the solution✅ . Thanks!
