I think my most cringe-inducing story (of this kind) is receiving an 'is this thing working?' email test from a sender, identified by name, at a professional sports team (probably you've heard of the team). I didn't know the sender and had no work or business connection to the team - they seemed to have sent it to everyone in their customer database, which I guess is > 1 million. I felt so bad for the sender. (And also for whoever made that possible!) Come to think of it, I don't recall any reply-all responses, so they must have effectively bcc'd everyone at least. Thank goodness! I can't even imagine ...
