Re^2: adding carriage return to gmail script

No need for join. Use $" ($LIST_SEPARATOR).

Technically, that's correct. Realistically, that's a terrible solution -- putting newlines in between each of the elements in the list is a much clearer way to write this code. Keep in mind that your code should strive to be as clear as possible. That usually doesn't mean that it should be as clever as possible.

Yes, we should strive for clarity. I fail to see how using a perl feature exactly as it is intended is less "clean" or "clear" than code which simulates that feature. I doubt that there is single right answer. We have given the OP a choice. Neither of us should be too concerned about his choice.
