I don't just mean emails that have the letters "FYI" somewhere, I mean emails that are literally just info or actions, not necessarily requiring any real response other than a "thanks for this"...
I asked because I got told off recently for not replying to emails of this kind! I felt that it's a waste of time, and just clogs up peoples inboxes with thank yous... particularly when I only work part time so by the time I see the email a couple of days have passed and the information is often old news...
AIBU/rude not to reply? Do you expect a "Thanks, will take a look at this" or "thanks, will do this by Friday"? Or is it unnecessary?
