Part of this "I'm going to do this unless you let me know otherwise" trick is not phrasing it like a question to reduce communication overhead. That way the receiver doesn't have to write a reply and you don't get another email to read (and for anyone CCed). Saying that, I like emoji reaction features like on GitHub and Google Docs where you can just give a thumbs up to acknowledge you read and agreed to something. Seems really unpopular with some on HN for some reason, but emoji reactions are a useful lightweight way to communicate that you're on the same page, rather than making someone go through the motions of sending a "Okay, makes sense!" comment for every little thing. A bit like an upvote.
