This is a plugin that has to be installed on the client? Can’t we just not install it?

The plugin is designed to be used by the person doing the email tracking, not by his email recipients, who may or may not be using Gmail.

The plugin is part of a larger system designed to turn Gmail into a CRM application. See streak.com.

If the recipient is not using Gmail.... There’s no way that Gmail is tracking any activity on the account without the user being aware and involved.
