No.

The email2 platform can keep a record of all trackable actions that occur on a Private Email Network (PEN). This can be necessary for regulatory compliance and certain legal functionality.

That being said, you can turn tracking 'on' or 'off' on a per message basis, and choose whether or not to share tracking with your recipients.

Turning 'off' tracking will cause the email2 Delivery Slip to report that tracking has been disabled.

If you choose to leave tracking 'on', but disable the “Share tracking” feature, then tracking will be available to you (the sender), but recipients will not be able to view message tracking information.
