It’s also such a dumb metric because most of people’s jobs are to click on links elsewhere on the internet, yet when it’s in an email, it’s bad? Unless you’re running an old browser or there is a 0 day, simply opening a link isn’t going to hack your system, but further actions by the user would need to be taken to be compromised. These simulations don’t account for that.

Unless the email client is blocking external images, a tracking pixel in the email would be enough to see that the email was rendered, and that the address is valid. The trainings specifically instruct you to review the contents of the email and check the email headers before clicking links, so that alone would confirm to a spammer that the email is valid.
