The quest for email privacy in a world full of trackers
Mon, 27th Nov 2023

In this age where our inboxes serve as gateways to our personal and professional worlds, understanding and safeguarding email privacy has never been more critical. The reality that we face today is one of covert surveillance, where every action within an email could potentially be monitored, catalogued, and exploited. This invisible invasion of privacy is not just an abstract concern; it is a tangible threat with real-world consequences.

Challenges to Email Privacy
Email trackers are often imperceptible and embedded in emails as minute images. The act of opening an email triggers these images, sending data back to the sender. It's a comprehensive analysis: not only when and where you open the email but also your interaction patterns, time spent, and engagement with links within the email are meticulously tracked. This surveillance extends to your behaviour on websites linked to these emails, painting a detailed portrait of your online persona tied to your email address. There are broader implications to this - the tracking might begin with your email behaviour but penetrate your entire digital life through targeted ads, cross-website monitoring through this ad network and other web tracking syndicates.

Consider a scenario: you receive a B2B marketing email and click through to a linked webpage. Your visit, mainly your focus on the pricing chart, is silently logged. Such detailed insights can fuel targeted advertising from the sender and influence your decision-making. The ads for the product could be propagated throughout the rest of your browsing experience.

The sophistication of tracking software now extends to monitoring the opening of email attachments. Vendors employ specialized links within these attachments that when interacted with, relay information through their servers. This advanced method mirrors the tracking of email opens but utilizes embedded links in the attachments as the trigger. When a recipient engages with an attachment, the sender receives a notification through their analytics dashboard, indicating the interaction. More alarmingly, in the wrong hands, this data becomes fodder for sophisticated phishing attacks.

The threat extends beyond privacy. Malicious actors embed trackers not just to gauge interest but to profile potential victims for fraudulent schemes. Such tactics underscore the dual nature of this issue: it's not only a matter of privacy but also of security. The same mechanisms enabling marketers to study your email habits are ripe for exploitation by cybercriminals, who can use them to launch phishing attacks, spread malware, or execute ransomware.

The Antidote
So, what can be done? Just like traditional browser security settings to block all scripts and trackers globally, requiring much sacrifice to user productivity, a simple solution lies in altering your email settings to prevent automatic image downloads. This measure comes at the cost of convenience and a seamless email experience. Companies like SquareX are stepping up to restore security. With features like the 'Enhanced Privacy Mode' integrated into email platforms, users can view emails without triggering trackers, ensuring their actions remain unmonitored. Clicking on email attachments or links automatically opens them safely in secure, isolated environments in the cloud, such as in Disposable File Viewers or Disposable Browsers respectively, providing email readers complete privacy and security. This initial feature serves as a stepping stone towards a suite of more comprehensive security solutions.

The conversation about email privacy is not just about preventing unsolicited marketing; it's about protecting ourselves from threats like phishing and malware. Simple steps like changing email settings to block automatic downloads help, but using stronger tools like SquareX's 'Enhanced Privacy Mode' is even better. By understanding these risks and using the right tools, we can better protect our email privacy and improve our overall online safety. Privacy is our right.
