While Apple has relied on Intelligent Tracking Prevention (ITP) to protect Safari users for years, the newest iOS iteration strengthens ITP by hiding user’s IP addresses from trackers. This change makes it impossible to leverage user IP addresses to track an individual across several websites, making it more difficult to flesh out a complete and useful user profile.
With the Mail App, the MPP feature protects everyone by uk business email list preventing senders from using invisible pixels to gather user data. Emails are first downloaded and opened through a proxy server. Thanks to the software update, senders will no longer know when an email has been opened unless the iPhone user opts into this type of tracking.
This will likely result in three major changes for marketing metrics:
as they’re filtered through the proxy server, showing inflated and inaccurate open rates.

Every user request is sent through two separate internet relays. The first gives the iPhone user an anonymous IP address. The second server decrypts the web address then sends it to the proper destination.
