Suppose you win a university-wide award for your research and you receive an e-mail from one of the dean's secretaries with the dean and your department head CC-ed.
Is there an established etiquette for how to respond to such an e-mail?
I was in this situation: I replied all (in two sentences) that this was great news(!) and thanking the secretary for letting me know.
My advisor subsequently upbraided me as an ignoramus and suggested I send very personal e-mails to the dean and department head telling them how much the award meant to me.
Culture shock I guess because sending such e-mails seems vain to me, first of all, whereas I would prefer focusing on it as a win for the team and otherwise minimize attention drawn to it (hence it's great news, full stop), not to mention getting back to work. (Also, I guess if I were receiving an outside scholarship with funding from a donor, the university would arrange for me to write a careful thank you letter --- which would go out in hard copy --- quite a different scenario.)
