    What email encryption means

    ~15s
    Encryption scrambles your email so only the intended recipient can read it. Without encryption, emails are like postcards — anyone handling them along the way could potentially read them.

    Types of encryption

    ~15s
    TLS (in-transit): Most email providers use this automatically between servers. End-to-end: Only you and the recipient can read the message — not even the email provider.

    Gmail confidential mode

    ~15s
    In Gmail, click the lock icon when composing. Set an expiration date and optionally require a passcode. The recipient cannot forward, copy, or download the email.

    When you need encryption

    ~15s
    When sending sensitive information: Social Security numbers, financial data, medical information, legal documents, or private business communications.

    Practical alternatives

    ~15s
    For sharing sensitive documents, consider password-protected PDFs, secure file sharing (Google Drive with restricted access), or encrypted messaging apps like Signal.
