Modern plaintiff litigation rarely lives inside email alone. Today’s case evidence often sits across text messages, mobile extractions, collaboration platforms, chat applications, social media platforms, and enterprise communication tools that create fast, informal, and often highly revealing records. For plaintiff firms, that shift matters because some of the most important evidence in a case now lives in the short, immediate conversations people have on their phones and workplace platforms.
A witness may send the formal version of a story by email, but the real reaction may appear in a text thread. A manager may avoid saying something directly in a memo, yet discuss it in a Teams chat. A group may coordinate around an issue in Slack, then leave only fragments of the same topic in email. In employment cases, personal injury matters, product liability actions, and other plaintiff-side litigation, these modern data sources can carry some of the most candid and time-sensitive evidence in the record.
That is why collection and organization matter so much. From a digital forensics standpoint, Page One can assist plaintiff firms with identifying, collecting, and exporting mobile and modern communication data in defensible ways, helping preserve the context needed for review and downstream use. That practical support is important because modern data is not always handed over in one clean format. It may come from forensic collections, provider exports, device extractions, enterprise platforms, or third-party tools, all with different structures and metadata.
RelativityOne is well suited for that reality because it created the Relativity Short Message Format, or RSMF. RSMF is designed for workflows involving short message data such as enterprise chats, SMS, and social media applications, and that the format allows teams to efficiently search, review, and produce this information.
That matters in practical terms. Plaintiff firms are often dealing with multiple communication sources in the same case, and normalized handling creates consistency. Rather than treating each chat platform as a separate review problem, teams can work toward a more unified approach inside RelativityOne.
Slack JSON exports and Microsoft Teams PST exports can be converted to RSMF through Processing (if properly handled/exported).
For plaintiff firms, this is valuable because it aligns with how evidence actually arrives. Sometimes the data comes directly from a platform. Sometimes it comes as an export. Sometimes it comes through a forensic workflow that needs normalization before review. Page One can help bridge that gap on the front end, then RelativityOne can help manage and review the result on the back end.
Once ingested, RelativityOne offers strong tools for making short message evidence usable. The Short Message Viewer allows reviewers to search participant names, specific statements, and even emojis within conversations. It also includes a Timeline Navigator to help teams locate what was said during a particular time period. Relativity further notes that users can search individual messages and message metadata and apply coding decisions at the message level.
That is especially useful for plaintiff-side litigation, where precision matters. Attorneys do not always need an entire chat history treated as one undifferentiated block. They may need to find the specific message where notice was given, where a concern was dismissed, where someone admitted knowledge, or where an internal reaction contradicts a later position. Message-level searching and coding help teams get more targeted in how they analyze and build the case.
Processing also matters. When ingesting RSMF files it extracts the appropriate metadata header fields and properly links families and attachments for a better near-native review experience. Proper processing helps ensure message-level metadata is available for short message search and message-level coding, and that extracting children is important so attachments are not missed.
In real litigation, context often lives in the attachments, reactions, timestamps, participants, and conversational flow surrounding a message. A clean review experience makes it easier for plaintiff teams to evaluate not only the statement itself, but who made it, when they made it, who else was in the conversation, and what supporting material traveled with it.
The larger takeaway is simple: modern evidence requires modern handling. Plaintiff firms can no longer assume that the key facts will be found only in traditional email review. Texts, chats, mobile data, and collaboration platforms are now central to many cases. With Page One assisting on the collection and export side, and RelativityOne providing a practical framework for ingesting, searching, reviewing, and organizing that data through RSMF and related tools, plaintiff firms can manage modern evidence with more clarity and less chaos.
That means less time fighting formats and more time building the story that actually wins the case.
