A web application for managing multiple matters may have an email interface that may be used to update status items as well as upload and categorize documents. The web application may authenticate the source of the information, and may apply the various input received via email to an appropriate matter. The email interface may generate email queries for users, and the queries may include various identifiers that may be used to apply a response to the appropriate matter. The email interface may allow a user to create new matters or activities within matters. An email's subject line, contents, attachments, or other information may be analyzed.
