# Email Tracking

{% hint style="info" %}
Almost all emails today are sent and read in HTML. You can think of an HTML email like a static web page with text formatting, custom fonts, and most importantly, embedded images.&#x20;
{% endhint %}

Don't worry, email tracking doesn't mean someone has read all of our personal emails.&#x20;

Therefore, the pixel technology I mentioned above means that when you open an e-mail, your device can send a request to the pixel server depending on the e-mail client you use.

They usually contain information about which email was opened and which email address it was originally sent to.&#x20;

But the real risk here is that about 30% of emails leak this information to third-party tracking technologies. Also, about 80% of leaked data happens over untrusted, unencrypted HTTP.&#x20;
