Most companies will set their mail systems to block HTML-embedded objects in messages for security purposes. Microsoft Outlook, for example, will allow users to block embedded graphics in e-mails from all sources, or only display them in e-mails from sources in the user's contact list.

The second message included information about his location, the e-mail client he had used to open it, and the exact time it had been opened.

The Web pages you visit and the HTML-based mass e-mails you open are logged and tracked by advertisers and marketers. Companies track what you do at work through deep packet inspection to make sure you don't wander into territory forbidden by company policy, or dump corporate data to a remote server just before you give notice. Everything on the Internet is monitored in some way.
