Overview
- The original address becomes a non‑deletable alias that still receives mail and remains valid for signing in to services like YouTube, Drive and Maps.
- Account content stays intact, with emails, photos, contacts and purchases preserved under the updated address.
- Changes are capped at three per account with a 12‑month wait between updates, and aliases cannot be reassigned to others.
- Availability is limited during a phased rollout noted first on the Hindi support page, and Google has issued no formal announcement.
- Google warns of possible Chromebook sign‑in loops and third‑party “Sign in with Google” mismatches, which may require device resets or manual email updates.
