So here's something or nothing: I sent a mail to myself via our bulk mailer and can see what I've been doing even though I have #Apple's #MacOS 'Mail Privacy Protection' switched on? Irrespective of what Apple says, the click-thrus I kinda get given they include UTM cruft, but I thought just opening would be opaque.
Or am I misinterpreting Apple's description (as per the alt-text) of what it offers? #privacy #tracking #surveillance
