They’ll learn you received it, not when you opened it (as the image is downloaded either way), and won’t be able to get any metadata (ip based location, browser headers).
Gmail uses a similar technique to mask metadata, though iirc they do download the images only when the email is first read by the recipient.
- odysseus 4y agoIf you don't open the email, and don't have the preview pane on, how would the image get downloaded either way? If you do open the email, and the spammer maps, say, snotrockets@example.com to a unique AD-SRE21234.JPG filename and that image within the email is displayed, no matter if it goes through Apple's relay or not, wouldn't the spammer then be able to validate your address is both valid and actively opening spam mail at whatever time you opened it?
