I'm often in situations where I'll send an email like this one:
Hi, thing X will be getting done next week
I'll get a response,
OK, I'm glad to see it's going well.
Odd question: I always feel that it is polite to say something like "thanks" to that, but it's also a waste of an email and potentially someone's time. However, I feel like I'm being rude by not acknowledging a compliment. I'm over thinking it, but is there a procedure I can follow in situations like this?
