To help protect your privacy and ensure intentional communication, we are introducing a new caution notification in Gmail. This feature is designed to prevent accidental information disclosure by alerting users when they are about to "Reply All" to a thread where they were originally BCC’ed.
Previously, users might inadvertently reveal their presence on a confidential thread by hitting "Reply All" while BCC'ed. With this update, Gmail will now display a prominent warning prompt to confirm your intent before the message is sent to all recipients, ensuring that your participation remains private unless you choose otherwise.
Getting started
- Admins: This feature is available by default.
- End users: This feature is available by default and will trigger automatically when a BCC'ed recipient attempts to "Reply All" on a thread.
Rollout pace
- Rapid Release and Scheduled Release domains: Available now
Availability
- Available to all Google Workspace customers, Workspace Individual subscribers, and users with personal Google accounts.
