Safari 27 Blocks Email-Based Tracking by Identity Providers Across Apple Devices
· 1h ago · Originally reported by PPC Land
Apple's Safari 27 update now blocks identity firms from converting email addresses into tracking IDs, applying this restriction across iOS, iPadOS, macOS, and visionOS. The new policy is enforced at the domain level and does not allow exceptions, though no specific vendors were named.
Why it matters
This move further restricts how advertisers and identity providers can track users for ad targeting and measurement, making it harder to use email-based identifiers on Apple platforms.
Explain it like I’m new here
It's like Apple putting up a fence so companies can't use your email to follow you around the internet.
