Anyone know what the author was referring to here when saying "fonts"? My impression was disabling images and not clicking links made it impossible to track the opening of an email.
- quanticle 11y agoI believe he was referring to web fonts [1], which, like images, can be configured to be downloaded from the sender's server, thus informing them that you opened the e-mail.

- ubernostrum 11y agoI'd guess they're talking about using web-loaded fonts in an HTML message? In that case you'd know when the user fetched the font.
