Apple recently removed a mention of "Hide My Email" support in third‑party apps from the macOS Ventura features page on its U.S. website, as noted by French website MacGeneration. The feature was still listed on the page as of August 3, according to the Wayback Machine, but it was removed at some point since then.
Apple's website said that you would be able to "keep your personal email address private with Hide My Email in third‑party apps" with an iCloud+ subscription. It is unclear why Apple removed the feature from the page, but it may be due to the fact that it is already possible to create randomized email addresses with Hide My Mail via the System Preferences/System Settings app or on iCloud.com and use those emails in third-party apps on the Mac.
The feature is still listed on the macOS Ventura page in many other countries, but Apple likely hasn't got around to updating its regionalized websites.
Hide My Email was first introduced on the Mac with macOS Monterey last year. The feature can generate unique, random email addresses that automatically forward to your personal inbox, allowing you to hide your actual email address for increased privacy. On macOS Monterey, the feature is directly integrated in Apple's Safari and Mail apps. In the Mail app, Hide My Mail can be found in a pop-up menu in the "From" field.
Hide My Mail is included for no additional charge with iCloud+ storage plans, which start at $0.99 per month in the U.S. Hide My Mail is also available when creating an account in Safari using the "Sign in with Apple" feature released in 2019.
