Interesting, I wonder how it would look if you bring in the new items with minimal info and then when scrolled into view more info reveals. Like perhaps buttons start showing up, miniature stats graphs, subtitle, description, stuff like that. Could be a fun experiment, though maybe not that useful 😅

For example, I get a mail with the contents "T est", you get the same mail but it says "Te st" instead. If you make a screenshot or copy paste "Te st", they'll know it was you who leaked the contents as you were the only one with the space in that position.

They basically send a unique mail to each recipient, in every mail the spaces are placed differently so the mail is uniquely identifiable if someone were to screenshot or copy paste it somewhere without modifying it.
