What comes before "send this email" prompt needs to be shown to make
the argument more convincing, but with "..." there is no cue to decide
if the output is hard to read.

"prompt separator" sounds more like a separator that separates
prompts, but that is not what is going on, no?

Do we even need that new varible in the first place?  I am wondering
if you can just do the print "\n" right where you assign to that
variable.

When $confirm is set to 'never', you have both $needs_separtor and
$prompt_separator set.  Would it mean you'd have two extra blank
lines for that message?

All these questions you should have been able to avoided with a bit
more helpful explanation in the proposed log message, I hope.

Thanks.
