Send a message securely

    A message editor window opens.

  4. Toggle Secure send to ON .
    If you are sending a Zivver message to a recipient for the first time, you will be asked to set a verification method.

Security notifications

Your organization has rules in place to ensure that sensitive information is always sent with Zivver. Zivver uses security notifications to inform you when a rule has been triggered.

Read receipts

You can view a read receipt for each sent message. This way you know who has read your message and who has not. You will find this confirmation as a small envelope icon in the lower left corner of a sent Zivver message. Click the icon to see if the message was opened.

Message revocation

Zivver messages can be revoked at any time after sending, either for all participants (including the sender) or just for recipients. Message revocation can be scheduled for a set period or occur immediately. Revocation serves two purposes:

  • To withdraw a message sent in error.
  • To comply with legal or organizational policies requiring that messages not be retained indefinitely.

You can revoke sent messages or set them to expire before or after sending.

Set revocation for new messages

  1. Click the revoke icon at the bottom of your message editor.
    A new window titled Revoke appears.
  2. Click Revoke for recipients if you want recipients to lose access to the message.
    OR
    Click Revoke for everyone if you want both recipients and yourself to lose access to the message.
Warning
If you choose Revoke for everyone, the message becomes inaccessible after the set period. You cannot recover those messages.
  1. Click Revoke in to revoke the message later
    OR
    Click Revoke now to revoke it immediately.
    This option is not available for messages you are still composing.
  2. Set a time period using the input box and drop-down selector. Your organization may have set a default period.
    The scheduled revocation date displayed changes according to your selection.
  3. Click .
    If you selected Revoke in, a light blue banner appears above the message header showing the revocation period.
    If you selected Revoke now, a banner appears stating that access was revoked, and the message background turns gray.
Note
Revoking a message removes it from the Zivver inboxes of all recipients, including those in CC: and BCC:.

Change revocation settings for sent messages

  1. Go to your send Sent messages folder in Gmail.
  2. Open the message you want to revoke or update. Zivver messages contain the string [This message is encrypted with Zivver] in the subject line.
  3. Click in the top right corner of the message pane.
  4. Make changes as needed.
  5. Click .
  6. Optional: To remove the scheduled revocation, click .

Recipient verification

Zivver verifies recipients’ identities by checking whether they possess a preshared secret—usually an access code provided by another means than email. For details, refer to Verification Methods.

Personal settings

Click your account in the extension menu to change Zivver settings. See the Zivver WebApp user manual for more information.

Business rules

The Zivver Chrome Extension for Gmail monitors the Gmail editor window and may produce warnings when you add sensitive information or trigger another business rule. Violations may prevent the client from sending messages through Zivver. Depending on the rule’s warning level, the button may be disabled.

To address this:

  1. Click in the top right corner of the editor.
    A window titled Potential Issues appears, listing issues and possible actions.
  2. Click to ignore a particular issue.
  3. Click to close the notification window and return to the editor.
  4. Change or remove any elements that triggered the warnings.
