Emails sent with Gmail’s end-to-end encryption are extremely secure because only the sender has control over the encryption key, which is stored outside of Google’s infrastructure. Users can click the padlock by the Bcc button and press Turn On under the Additional Encryption’ option to apply it.

Gmail enterprise users will soon get access to a simpler E2EE process, and anyone can receive encrypted emails.

Google has introduced a new end-to-end encryption (E2EE) feature in Gmail, enabling organizations to send encrypted emails that even Google cannot read to other Gmail users. Later this year, the feature will be expanded to allow the sending of encrypted emails to any email users, including those from other providers.
