Describe the issue/error/question
This is my main flow to iterate through / loop through all the mails in batch;
This is my subflow;
- Does “adding wait node” after post http request make sense in the subflow?

Information on your n8n setup
- n8n version:last version of n8n cloud
Hi @onurbolaca, it can make sense. The execution of your parent workflow would only continue once the last node of your sub-workflow has been executed, so if you want to add an intentional waiting time this could be useful.
It does however take away a bit of visibility as the parent wouldn’t see which node exactly is currently running in the sub-workflow. So unless there are any memory limits at play here I’d try adding the wait to the loop in your parent workflow instead.
