What Apple does is load all images in all emails on their server, instantly when they arrive, before you open the email or not. So the sender can't know if you saw the email and track email open rates.
I think Gmail does the same now too, I tested that site with my Google Workspace address, it got hard spam filtered (never even reached the spam folder) but it still saw 3 image loads from a google server.

And use https://www.emailprivacytester.com to test that your email client is configured correctly
What’s interesting to see here is Apple’s "Protect Mail Activity" option working as advertised.
Loading images through their servers and throwing off the tracking software.
It still says you loaded it though.

Also does not work with fastmail.com adresses
Was a local error. Fixed now
Curious, what was the result for fastmail.com addresses ?
ERR connection refused like error. I guess gmail doesn't like them
Sorry about that. Try again now
