Email sits at the center of most document reviews, and you shouldn't have to juggle mail clients or file downloads to read messages. The email viewer displays EML, EMLX, and MSG files with formatted headers (From, To, CC, BCC, Subject, Date), renders body content as styled HTML or plain text, and pulls out attachments as separate files for individual review. PST archives are processed during upload to extract each email automatically.
Supported email formats
Hintyr supports the most common email file formats used in document review and productions. Each format is processed during upload to extract headers, body content, and any embedded attachments. Here are the supported formats:
- EML - The standard internet email format. Most email clients export this format, including Outlook, Thunderbird, and Gmail.
- EMLX - The email format used by Apple Mail on macOS.
- PST - Personal Storage Table files from Microsoft Outlook. A single PST can contain thousands of emails. Hintyr extracts each one as a separate file during processing, and the extracted emails open individually in the email viewer.
- MSG - Individual email message files from Microsoft Outlook. These are commonly produced during discovery.
When you upload a PST archive, Hintyr processes it and breaks it into individual email messages. Each one appears as its own file in the document browser. That means every email within the archive is individually viewable, taggable, and searchable during your review.
Email headers in the email viewer
When you open an email, the header section appears at the top of the panel with clearly labeled fields. Here's what the viewer extracts and displays:
- From - The sender's name and email address.
- To - The primary recipients of the email.
- CC - Any carbon copy recipients, if present.
- BCC - Blind carbon copy recipients, if available in the file metadata.
- Subject - The subject line of the email.
- Date - The date and time the email was sent.
Every header field is indexed during processing. That means the agent can search for emails by sender, recipient, subject line, or date. The Table of Contents tab in the document browser also uses these fields to organize your emails by people and dates automatically.
The header layout is designed for quick scanning. Fields appear in a consistent order with labels on the left and values on the right. You can tell at a glance who sent the email, who received it, and when.
Email body display in the email viewer
Below the headers, the email body shows up in its original format. HTML emails render with their styling intact, including fonts, colors, links, and inline images. Plain text emails display with their line breaks and spacing preserved.
Email threads that include quoted replies display the full conversation chain. Scroll through the body to see the original message and all replies in sequence. This is especially valuable when earlier messages give you context for understanding the full thread.
The full text of every email body is extracted and indexed for search. The agent can locate specific phrases, names, or topics and provide citations that link back to the source email.
Email attachment handling
When an email has attachments, Hintyr extracts each one as a separate file during processing. These extracted files appear as child documents nested under the parent email in the Uploads tab of the document browser. This parent-child relationship makes it clear which attachments belong to which email.
Each attachment is treated as a fully independent file within the case. It gets its own file type icon, processing status, and actions menu. Click an attachment to open it in the right viewer: the PDF viewer for a PDF, the image viewer for a photograph, or the spreadsheet viewer for an Excel file. Every attachment is also indexed by the agent, so you can search across email attachments just like any other file.
You can tag, assign custodians, and apply other file actions to individual attachments independently of the parent email. If only one attachment matters to your review, act on it alone without affecting the email or its other attachments. Bates numbering and redaction availability depends on the attachment's file type.
