ProtonMail has introduced an enhanced email tracking protection system for its web-based email solution that prevents senders from being tracked by recipients who open their messages.
ProtonMail is an end-to-end encrypted email service based in Switzerland and uses a client-side encryption approach to maintain user privacy and protect their communications from snooping intermediaries.
Email trackers are predominantly used for targeted advertising but can also be used for de-anonymization, to expose the recipient's information to third parties, or simply to monitor when someone has read your email.
ProtonMail will now start blocking email trackers by default on all accounts, including free users.
ProtonMail users can check if this privacy feature is enabled by going to Settings > Email Privacy and confirming if the Block email tracking setting is toggled on, as shown below.
If you're not using ProtonMail, but you still want to protect yourself from email trackers, try disabling image/resource loading on your email client.
