I don't dispute that it's undesirable that the admin can only email in the language currently in use by the administrator.
But, to fix that is extremely difficult in Zen Cart v1.x.x.
However, due to some slick architectural changes in v2.x, it's looking like we'll be able to make it send emails in the language used by the customer when the purchase was made.
So ... while you may want to raise numerous bug reports about the fact that you don't like that it can only send from one language, it's not going to be fixed in Zen Cart v1.x.x. Stay tuned for v2.x in the near future, where it'll be more possible. Until then, duplicate bug reports about your wished feature will be ignored. Sorry.
And please don't hijack someone else's discussion of a very different matter just to slide in your complaint another time.
