Hillary Clinton is in the hot seat for commingling her work and personal email accounts, but even in a typical workplace mixing the two can lead to the leak of proprietary information, unnecessary exposure to e-discovery and internal unrest.

According to Ballard Spahr LLP’s Philip Yannella, there are technological means for reinforcing boundaries. Companies can use data leakage prevention software that scans outgoing emails for particular domains or keywords to monitor emails sent from work accounts, Yannella said.

Ballard Spahr’s Louis Chodoff also warned about the scourge of autofill, a function that presupposes the intended recipient of an email. “I’ve done it so many times where you just click and are sending an email to the wrong person,” he said. “You could be sending proprietary information to Bob Johnson and accidentally send to Bob Smith, who works at a competitor.”
