While you’ve likely never heard of companies like Yeswear, Bananatag, and Streak, they almost certainly know a good deal about you. Specifically, they know when you’ve opened an email sent by one of their clients, where you are, what sort of device you’re on, and whether you’ve clicked a link, all without your awareness or consent.
That sort of email tracking is more common than you might think. A Chrome extension called
Ugly Mail shows you who’s guilty of doing it to your inbox.
