Bar panels in at least four jurisdictions now say it is unethical to use “web bugs” or other email tracking software to monitor how and when recipients review and circulate emails and other electronic documents.
With some email apps offering read receipts, email tracking is pretty easy for anyone to set up. Many people, lawyers included, probably enable it without second thought. Something to have on your radar. UPDATE: In Illinois at least, certain types of read receipts are acceptable.
