One of the new features of Apple’s highly anticipated iOS 15 is Mail Privacy Protection, which will combat the tactical but increasingly common methods some advertisers use when they sneak trackers into emails.

For a long time, email advertisers used undetectable tracking pixels hidden in the empty white space of an email to collect a lot of recipients’ data for resale.

To understand the work of Mail Privacy Protection and how to solve this problem, Apple said: “Mail Privacy Protection downloads remote content in the background by default … all remote content downloaded by Mail is routed through multiple proxy servers, preventing the sender from learning your IP address. As a result, email senders will only receive generic information rather than information about your behavior.”
