Did you know that opening an email can send a world of information back to its sender? It can. Including when you opened it, how many times you opened it, where you were when you opened it, and much more. Like Apple iMessage and Facebook Messenger receipts, emails can share detailed information about when a recipient views a message and their actions. If you want to keep your email private, follow this guide on keeping your emails from being tracked.

How are emails tracked?
Pixels are one of the most popular ways to track an email. A small image, the size of a single pixel, is often attached to the email’s end. When your email client loads the picture, your email service must retrieve it from the sending server; this server can then log when your email service loaded the image to understand when (and if) you opened the email. Additional information, such as your IP address, can alert the server to where you were located when you opened the email.
How can you stop tracking?
To stop tracking, the easiest option is to disable your email client from automatically downloading images; this way, the sending server can’t load its tracking pixel. There are also browser extensions that can analyze your web-based emails and alert you if there is a tracker in the data.
If you want to prevent your email client from downloading images that are included in emails, you’ll follow different steps according to your provider.

What extensions are available?
You can also download browser extensions that can protect your privacy by alerting you if an email includes a tracker. Our top recommendation is PixelBlock for Google Chrome; it blocks pixel trackers and notifies you when any tracking attempts are made.
A second option is Trocker for Google Chrome and Mozilla Firefox, which does the same. Both of these extensions provide quality online security to prevent email tracking.
