I'm glad the reference helped you resolve your question.
From your macro:
I have a couple suggestions:
- Use Local Variables wherever possible when you don't need the Variable later.
- This helps keep your KM Variable environment clean, and free of large Variables.
- When you are concatenating data, put the repeating Variable on the same line as the collecting Variable, followed by a linefeed.
- Otherwise, you will have a blank line at the beginning of the list.
- You can also use a manual RETURN instead of the token
%LineFeed%
So, it might look like this:

I replaced
Your Variable With
temp Local__AllEmails
ExtractEX Local__ExtractEX
