Apple changes Sign in with Apple relay domain
On August 24, 2026, Apple announced that new Sign in with Apple relay email addresses previously issued on privaterelay.appleid.com will be issued on private.icloud.com starting later in 2026. Existing privaterelay.appleid.com addresses will continue to work and forward mail without interruption. Apple confirmed iCloud+ "Hide My Email" addresses will remain on icloud.com. Developers are instructed to update account systems, email validation logic, and allowlists to accept the new private.icloud.com domain in addition to the existing privaterelay.appleid.com addresses.
A technical domain change from Apple affects Sign in with Apple email-relay addresses and requires developer action on authentication, email validation, and allowlists — a platform-level identity change with broad developer and ecosystem impact.

Permutive and TransUnion Partner to Enhance Sell-Side Curation
Permutive and TransUnion have announced an integration that enables publishers using Permutive's DMP to match their first-party audience data with TransUnion's identity graph and activate TransUnion audiences across Permutive's global publisher network. This addresses the limited addressability of the open internet, where only about 30% of traffic is addressable via cookies or alternative IDs, by leveraging multi-signal identity strategies. Early testing with a financial services advertiser showed a 12x increase in addressable impressions, a 5x increase in consumers reached, and a 170% overshoot of the KPI target. The partnership aims to provide a viable alternative to walled gardens, reduce data fees, and monetize previously unsold inventory, ultimately improving campaign accuracy and performance.
