Oh hell yes, this is definitely a thing with lots of people. It's one of those WTF realizations that everyone who works in a corporate environment gets slapped in the face with really hard.
There are certain people for which you MUST give 1, maybe 2 sentences at a maximum, address them by name, AND, make sure that they're the only person in the "to:" field. Anything different and you risk ghosting or first-thing-only response.
If there's other folks in the cc who I know may actually read for context, I will add a '"*** details ***"' separator after a few blank lines and then write up normal paragraphs. I know the "details" stuff will get ignored by the target, but that's OK. It's just there for reference and for others who may chime in.
