To an outside observer, what I’m trying to do might not seem to make much sense.
To understand why I want it this way, it helps to know that years ago I faced the challenge of transferring Safari content and open tabs from my iPhone and iPad over to my Mac.
This thread solved it for me — simply, definitively, and reliably:
I still have some old emails from before that time, and for those, archiving them as .eml or .mbox files doesn’t really make sense — at least from my perspective. The most practical solutions are either PDF files (created via Export as PDF, not via Print) or plain text files.
Since I currently have some spare time, I decided to finally tackle this project.

Because the AppleScript version doesn’t run reliably for me (for reasons I haven’t figured out), I created a simple Repeat for Each loop, which works perfectly for my purposes.
I’ve marked your AppleScript solution as the official answer.
Attached below is the Repeat for Each macro template I created for myself:

According to ChatGPT, the “Arrow Down” action should be placed at the beginning, but personally, I find it works better at the end.
