Check if friends or colleagues track you via email
Creep Alert is the Chrome extension for Gmail that gives you an alert when someone tries to track you via email. It also blocks read-receipts and hidden tracking pixels.
HOW IT WORKS:
When a tracker is detected, it blocks it and shows an alert icon next to the sender's name. By clicking the alert icon, you will also be able to send a prewritten and polite response to the sender, informing them that you are not ok with being tracked.
