Apple announced earlier this year that with the update to their operating system with iOS 14, consumers would have more control over the information that apps could track via the IDFA (we explored the effect this would have on marketers here). Now with the announcement of iOS 15, Apple is putting yet more control in the hands of consumers by extending privacy protection to email and other often-used services on all their devices.

These include "Hide My Email" and "Mail Privacy Protection", both of which limit how much data can be collected and tracked from email clicks and opens, especially targeting the swath of junk mail that comes in through an IP identification. This of course also affects marketers, who rely on this same data to serve personalized messaging to consumers. Rather than look at this as a hindrance to marketing efforts, however, brands can use this as an opportunity to increase trust among consumers, but also to rely on forming different types of relationships with them that still protect their privacy.
