Big brands, business sites and other marketing companies are the equivalent of a Cookie Within emails to track your habits and uses. According to a study, one in two emails today has an invisible pixel!
The three emails include two small cookies, which allow the sender to know the recipient’s reaction. This is it In a survey conducted with Sending message . To sites And for ad tracking, we’re talking about a “cookie” and for emails, it’s a ” .
Why this word? Because it is aIt is invisible to the recipient and is hidden in the message to track the applications of internet users. “Physically”, it takes the shape of a pixel in a pixel image, which is often undetectable because it is transparent. This is a bit the same functionality as a cookie, at this point, there is no alert, and the sender’s goal is to know when the message will open, from which type of device, and even from where to collect the cookie .
A cookie that monitors your habits
This is apparently a blatant violation of personal data, and according to Hayne co-founder David Heinmeyer Hanson, the average Internet user receives about 20 emails a day with a pixel tag. For 10% of users, this will increase to 50 messages per day. His study is based on about a million messages a day on his company’s servers, and the culprits are mostly business sites and marketing companies. The same It uses this system on its social network to target ads.
If we do not find this type of cookie in a relative or coworker’s email, it will be hidden in emails containing the subjectIn advertisements or sales. As soon as the pixel appears in the message, like any link or image, the sender is notified that the pixel is stored on their server, and viewing the message uploads the image Of the recipient.
For now, there are no complaints against this type of practice, but on the other hand, it can be defended against . By default, Gmail blocks displaying images in considered emails , But can do this for its entire inbox. In the parameters, you must access the “General” tab Check the “Ask for confirmation before displaying external images” box.
An option to prevent spying
We see the same option But even in Outlook, The Sending message , This is not a problem when you receive emails mainly with text. However, when there are images, it prompts you to enable the display option, so take the risk of being “discovered”.
This practice is not the same as allowing online couriers to “read” emails received to display content-based ads. Even if they are just bots, they can access the content of the messages for advertising purposes. At this point, a simple point-scale picture can do almost the same thing.
