I have recently started to communicate with scholars and administrators at an American institution (I myself am based in Europe) as part of a fellowship program. I have since then received several emails with general information which were addressed to me but likely sent in bulk to all participants. The director of the programme (herself a professor) and another administrator are also copied in the messages.
Should I reply to those emails with a "thank you" email? If so, should I include the professor and the other administrator in the reply?
