Digital tracking explained
What email tracking can reveal
Remote content can report a fetch to a sender. That event is different from proof that someone read a message.

Remote content can create an observation
Apple explains that remote content in email can expose information such as an IP address and when or how often a message was opened. Those requests can be used to build a behavioral profile. This is a mechanism described by the provider, not proof that a particular message contains a tracker. Apple: Mail Privacy Protection disclosure
Background loading changes the interpretation
With Protect Mail Activity, Apple describes downloading remote content privately in the background regardless of engagement. The practical inference is that an image fetch should not be treated as reliable proof a person read a message. Apple: Mail Privacy Protection disclosure
Choose a control with the right scope
On Mac, Mail offers Protect Mail Activity and separate remote-content controls when that option is off. Check the current settings rather than assuming that hiding an email address and controlling remote content are the same choice. Apple: Mail privacy settings on Mac
Questions and answers
Is a remote-image fetch a reliable read receipt?
Apple describes background downloads independent of engagement. A fetch therefore needs context before it can support an inference about reading. Apple: Mail Privacy Protection disclosure
