According to The Radicati Group, the average employee sends 36 emails per day. That extrapolates to approximately 10,000 emails per employee per year. And so, even in cases involving a limited number of custodians, the volume of emails at issue can be significant.
Email threading provides a number of benefits, including eliminating the need to review the same content multiple times and minimizing the potential for inconsistent coding of emails.
So what exactly is threading? It is a process by which emails are grouped together so they can be reviewed as a single coherent conversation. For example, if I write John Smith an email, John’s reply will very likely include my original message at the bottom of the email chain.
