By "positive response", are you saying that human "from" names yield a higher click-through rate?
Microsoft heard from hundreds of users who were heartbroken when Clippy was removed from Microsoft Word.
Case in point: Netflix's auto-play feature used to drive me bonkers, so much that I would try other streaming services first. How could they think this feature was a good idea? The only plausible explanation I've heard is that they were optimizing for user engagement. Users click around more to prevent the video from auto playing.
What I said also applies to any other metric, including (for example) income generation.
