How did they do it?

  • Used email threading to eliminate nearly 150,000 emails and more than 85,000 attachments from review
  • Saved their client an estimated $233,000

The Problem and Approach

Recently, Troutman Pepper eMerge assisted a client in responding to a government subpoena, in which they faced a review of 742,000 documents. Of those documents, 59 percent were emails—and those emails spanned 60 different custodians.

The team set up an analytics index for their document collection and employed several Analytics techniques, such as categorization. However, because of the large amount of emails in the data set, Troutman Pepper eMerge thought email threading might be particularly effective.

The Troutman Pepper eMerge team applied email threading to the 441,362 email messages in the data set. Relativity grouped these messages by conversation, identifying and labeling all inclusive emails. In other words, the software identified the subset of emails that contained either unique content that needed to be reviewed or entire conversations in the body of the message. By only reviewing emails and attachments that contained entire conversations, Troutman Pepper eMerge could avoid reviewing repetitive content such as the individual replies, forwards, etc. that were part of those conversations.

Fast Results

Troutman Pepper quickly determined that only 293,033 of their emails were inclusive and needed to be reviewed, allowing them to eliminate 148,329 of the emails—and 85,224 attachments to those emails—in their data set from review, as they were either non-inclusive or duplicates of inclusive emails.

As a result, Troutman Pepper’s team was able to focus their efforts on only 66.4 percent of their emails, significantly reducing the cost and time of their review.

Even with a conservative cost estimate of one dollar per document reviewed, email threading helped Troutman Pepper save their client approximately $233,000 by allowing their team to review only the inclusive emails and attachments from their document set.

“We were very pleased with the email threading results in Relativity,” said Chris. “Aside from helping us save time and money, the whole process took only a couple of hours to set up—which is just another reason it’s so enticing. It’s easy to use and a major cost savings.”
