Chapter 1: The Basics of Email Trackers

Email trackers, often referred to as 1x1 pixel trackers, are stealthy tools that operate without detection in your inbox.

It's increasingly challenging to maintain privacy in our online lives. Various entities, from government bodies to commercial organizations, are eager to learn about our preferences, behaviors, and social interactions. While most of us are aware of cookies—small data files that track our online activity—email trackers operate differently.

1. Email Trackers Bypass Permission Requirements

Unlike cookies, which are regulated to some extent, email trackers can be used without user consent. Current cookie laws restrict the type of information collected and often require sites to obtain explicit permission from users. In contrast, there are no such regulations governing email trackers, meaning they can be utilized freely, leaving users with no option to opt-out.

2. The Invisibility of Email Trackers

When an email lands in your inbox, there's no way to tell if it contains an embedded tracker. These trackers are essentially invisible—comprising a single transparent pixel—and without specialized software, you won't be aware of their presence.

3. Data Collection by Email Trackers

Upon opening an email, the email client or browser automatically requests the transparent image from the server hosting the tracker. This process logs the user's IP address and indicates that the email has been opened. More intrusive trackers may gather additional information, such as:

• Who opened the email and when
• The frequency of email openings
• The duration spent reading the email
• The type of device and operating system used
• Links clicked within the email

These trackers can collect extensive data without relying on cookies or access to your browsing history. Mainstream email applications like Apple Mail and Yahoo do not currently provide warnings or block these hidden trackers.

4. Implications of Collected Data

The data amassed by these trackers allows marketers to analyze optimal email sending times, user demographics, preferences, and more. This information is often justified as a means to enhance targeted services for consumers. However, it raises serious concerns about privacy and the normalization of such practices without regulatory oversight.

5. Protecting Your Privacy from Email Trackers

Here are several strategies you can implement to safeguard your information:

For Gmail Users:

Google has invested significantly in image proxies to protect users. When a tracker requests an image, Google modifies the request so that it appears to come from Google rather than the user, preventing marketers from logging the user's IP address and geolocation. However, this data is still retained by Google.

To enhance security further:

• In the Gmail app, disable remote image loading by navigating to Settings > Images and selecting "Ask before displaying external images."
• On a browser, adjust settings under General > Images to "Ask before displaying external images."

For Outlook Users:

Outlook.com uses a proxy to load images, providing some protection against pixel trackers.

For macOS Users:

If you're on Monterey, enable Mail Privacy Protection in Mail > Preferences > Privacy. For earlier versions, consider using extensions like MailTrackerBlocker or disable remote image loading.

For iOS Users:

Enable Mail Privacy Protection in Settings > Mail > Privacy Protection. Also, disable tracking requests in Settings > Privacy > Tracking.

For Windows Users:

Consider using Mailbird, which integrates various social media apps while safeguarding your information.

For Android Users:

Explore FairEmail, an open-source email application focused on privacy.

Browser Extensions:

Utilize tools like Ugly Email and PixelBlocker to identify and block trackers.

Catch-All Protection:

For comprehensive protection, consider a paid VPN service like NordVPN or a free alternative like ExpressVPN.
