Switch to Protonmail Reason #8: Reveal less about your device when you open tracked messages

Marketers can use email images to infer the type of device you use, adding detail to a customer profile.

Why this matters

Marketers can use email images to infer the type of device you use, adding detail to a customer profile. Privacy is easier to defend before this information is collected than after it has spread.

The protection

Proton's tracker protection removes known pixels and proxies other remote images.

Take action

Use the protected Proton app for reading mail. The sender may still learn details you volunteer through a form or reply. Email protection depends on the route and settings. Ordinary mail involving outside providers is not automatically end-to-end encrypted, and email metadata is not universally hidden.
