  • Can you download emails sent to you without the other person knowing over gmail?
    There have been some attempts by Google to restrict the amount of information that can be transmitted this way. For example,since 2013, Google has served all images in Gmail through its own proxy servers, which could hide your location from at least some tracking applications. And extensions such as Ugly Email and Pixel Block have been developed to block trackers on Chrome and Firefox. Source: over 3 years ago
