...that I somehow didn't ask anyone who the boss was, I could say:
"J'ai envoyé un courriel au chef de la compagnie. J'espère qu'il ou elle me répondra."
Literally: "I sent an email to the head of the company. I hope that he or she replies".
If the reply does come through, I'll simply check the signature and determine if the boss is a man or a woman. Alternatively, I can check to see if the head has written anything anywhere else: your conjugation changes slightly if you're a man or a woman. That's the thing I love about French: there's little clues everywhere and you gotta pay attention to all of them.
