I am in a formal setting whereby my superior pleasantly welcomed me in an email (tricky to say it is non-formal, it is formal but in a nice way) among other members. I want to reply to her via email, thanking her that she kindly introduced me to other staff (they are cc'd to the email) and at the same time trying to arrange an informal social meeting (informal, yet it counts as formal, because of superiority) for me with others.
I was about to reply:
"thank you for introducing me and arranging a meeting"
but I felt that this phrase does not show appreciation and is a bit "too" formal.
English isn't my mother tongue. How can I answer showing appreciation and warmth in a (not too) formal way ?
