Right now you probably understand that browsing the net leaves you ready to accept Email Tracking Blocker, website operators and advertisers. But less well known is you can be tracked by simply opening an email. Merely clicking or tapping to open a message can transmit to the sender not only that you opened it, but also where you were when you did so and also on what device, amongst other things.
The technology has been used by email marketers and Nigerian fraudsters for more than a decade. But recently, it has become an instrument used by employers, sales representatives, bill collectors, lawyers, political candidates, nonprofit fund-raisers and maybe also that guy you met in a bar and regrettably gave your contact information to.
Here’s how it operates: The sender in the email embeds a so-called web bug or pixel tracker into the content from the message or perhaps 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. Once 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 will is lure you into a web-based environment and also the collection that continues 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 focuses on privacy issues.
There is something you can do in order to avoid owning your email activity monitored. Perhaps the easiest defense is to adjust the settings of your own email program so there is absolutely no image rendering.
It once was set like that by default but a year ago, in a boon to marketers, Gmail made the setting an opt-out feature and lots of other email providers followed suit. Disabling images will sift and block images from incoming emails, including those tiny, pixel-size tracking bugs. You are able to click on the missing images you want to see and which of them you don’t.
“A more complex technique is to construct a private firewall that blocks images,” said Gerald Friedland, director of audio and multimedia research at the International Computer Science Institute at the University of California, Berkeley.
Or, he explained, you can simply turn off your Wi-Fi while opening and reading email messages. This, needless to say, assumes you aren’t checking your email on the provider’s website but rather using a retrieval program like Apple Mail or Outlook.
And don’t simply click any attachment while connected, nor a web link within the message, even if it’s the unsubscribe button. “The unsubscribe link is easily the most clicked item in emails so it’s often whatever they use to monitor you,” said H.D. Moore, a senior researcher using the Internet security consultant Rapid7. “As soon while you simply click it, they know everything about you.”
