e live in a world where
data about what you do is
very valuable, and people
who want this data
constantly look for ways to collect it. Your
email is one such resource, and it’s
possible your emails are embedded with
an image that’s practically invisible and
can be used to track you. This can be a
message sent from a massive company, a
tiny firm using a mailing list service to
manage its transmissions, or an individual
using mail software designed to embed a
tracking email.
Tracking pixels embedded in emails
allow a sender to know whenever the
message is opened and track each date
and time, and will alert them if the emailBlock tracking pixels in Apple Mail
Email senders, particularly from lists, try to figure out when and how often you open emails.
