At this point you most likely realize that browsing the net leaves you open to Email Tracking Blocker, website operators and advertisers. But less well-known is that you can be tracked just by opening a message. Merely clicking or tapping to open a message can transmit to the sender not only that you opened it, but additionally where you were when you did so and also on what device, among other things.
The technology has been utilized by email marketers and Nigerian fraudsters for more than a decade. But more recently, it has become a tool used by employers, sales people, bill collectors, lawyers, political candidates, nonprofit fund-raisers and maybe additionally that guy you met in a bar and regrettably gave your contact info to.
Here’s the way it works: The sender in the email embeds a so-called web bug or pixel tracker to the content of the message or possibly inside an attached PDF, Word or PowerPoint. These bugs are 1-by-1 pixel images (tinier than tiny), which can be invisible for the recipient. If the email or document is opened, the bug triggers your device get in touch with the sender’s server and convey all sorts of information.
“What it does is lure you into an online environment as well as the collection that goes on there without alerting you that it’s happening,” said Ryan Calo, a professor of law at the University of Washington Law School in Seattle who specializes in privacy issues.
There are some things that can be done in order to avoid having your email activity monitored. Probably the easiest defense is always to adjust the settings of the email program so there is not any image rendering.
It used to be set like that automatically but last year, in a boon to marketers, Gmail made the setting an opt-out feature and many other email providers followed suit. Disabling images will sift and block images from incoming emails, including those tiny, pixel-size tracking bugs. You can click on the missing images you want to see and the ones that you don’t.
“A more technical method is to construct a personal firewall that blocks images,” said Gerald Friedland, director of audio and multimedia research on the International Computer Science Institute on the University of California, Berkeley.
Or, he said, you could simply shut off your Wi-Fi while opening and reading email messages. This, obviously, assumes you aren’t checking your email on your own provider’s website but instead employing a retrieval program like Apple Mail or Outlook.
And don’t simply click any attachment while connected, nor a web link in the message, even when it’s the unsubscribe button. “The unsubscribe link is easily the most clicked item in emails so it’s often whatever they use to track you,” said H.D. Moore, a senior researcher with the Internet security consultant Rapid7. “As soon while you simply click it, they understand everything about you.”
