Email Threading and Reviewing Emails

What is email threading deduplication?

Email threading deduplication is a setting that Organization Administrators can enable or disable when setting up a project on Everlaw. Everlaw identifies duplicate emails using text comparison and email threading. It uses the email text content, metadata, and message IDs to identify emails that appear to fit into the same spot in a given thread. Specifically, email thread duplicates are determined by similar content, close timestamps, and various email header fields. If email threading deduplication is enabled, Everlaw will attempt to identify documents that fit in the same place in an email thread based on the documents’ contents and metadata. If this setting is disabled, you may see emails identified as duplicates in the email thread section of the context panel, but not the duplicates section. Email threading deduplication is turned on by default for new projects on Everlaw. You can reach out to or an Organization Administrator on your project to check if this setting is enabled and request that it be turned on.

How do you determine email threading? / My emails aren’t threaded correctly.

Everlaw uses emails’ content and metadata (such as sender, recipient, and date sent) to determine how they fit into threads. If you believe your emails have been threaded incorrectly, it may be because the necessary metadata values are missing. You can reach out to to see if this is the case.

What are embedded emails and how can I review them?

Embedded emails are emails that are attached to another email. Native embedded emails uploaded to Everlaw will have Parent ID and Family metadata values that clearly link them to the emails that contain them. (Before the March 2018 release, embedded emails were processed into separate families from their parent emails when uploaded onto Everlaw.) If the embedded emails on your project were uploaded to Everlaw after March 23, 2018, you should be able to view them within their families by using the attachment view in the context panel

The PDF and native versions of some of my emails look different. Why is this?

Native email files are sometimes formatted in ways that are misleading and non-intuitive for review. You may encounter one of the following two scenarios when reviewing emails in the native viewer:

  • Native Outlook files sometimes display the email body as an attachment to the rest of the email, instead of part of the email file.
  • When reviewing embedded emails (emails attached to other emails), you may find that the native view of the parent email displays the body of the attachment email, instead of the parent email.

For these reasons, Everlaw’s processing system has been designed to optimize email display in PDF or image view. It is highly recommended that you conduct review of emails in PDF or image view, as the emails will be more intuitively presented and readable.
