Overview
Thomson Reuters Case Center is a cloud-based digital evidence management platform designed for courts, law firms, and administrative hearing agencies. It organizes case materials including documents, multimedia files, and testimony into paginated, searchable case files with role-specific access controls. Case Center tracks participants (parties, attorneys, witnesses), case metadata, uploaded evidence, hearing schedules, and annotation notes. It does not function as a contact database in the traditional CRM sense — contact information is tied to case roles rather than maintained as standalone audience records. Mailchimp is an email marketing platform organized around audiences (formerly lists), contacts, and campaign automation. It tracks subscriber email addresses, first/last names, merge fields, tags, and segment membership. Mailchimp has no concept of cases, evidence, documents, hearings, or legal role types. The migration maps Case Center participant records into Mailchimp contacts — extracting email addresses, names, phone numbers, and role associations as tags or merge fields. Case file documents, multimedia evidence, hearing records, annotations, and workflow configurations do not have Mailchimp equivalents and cannot migrate. We export Case Center data via its API, transform participant records into Mailchimp contact format, and load into your Mailchimp audience. A delta-pickup window captures any new participants added during cutover. Workflows, automations, and templates must be rebuilt in Mailchimp independently.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Thomson Reuters Case Center object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Thomson Reuters Case Center
Participant (per case role)
Mailchimp
Contact
1:1Each Case Center participant record (name, email, phone) maps to a Mailchimp contact. When the same person appears in multiple cases with different roles, they create one Mailchimp contact with multiple tags reflecting each role instance rather than duplicate records.
Thomson Reuters Case Center
Case Role Type
Mailchimp
Tag
1:1Case Center role types (Party, Attorney, Witness, Court, Other) map to Mailchimp tags applied per contact. This preserves the participant's legal role without creating custom fields — tags are applied at import based on role-type values from Case Center. Each role receives its own tag, enabling segmentation of campaigns by role and allowing updates if a participant's role changes in Case Center, keeping the Mailchimp audience aligned with role assignments.
Thomson Reuters Case Center
Case Reference / Case Number
Mailchimp
Merge Field (CASE_REF)
1:1Mailchimp supports custom merge fields. We create a CASE_REF merge field on the audience and populate it with the Case Center case identifier so contacts retain their associated case context in Mailchimp records. This field enables segmentation by case number, lets you filter contacts for specific cases in reports, and provides a quick reference for support teams needing to tie Mailchimp activity back to the original case file.
Thomson Reuters Case Center
Organization / Firm Name
Mailchimp
Merge Field (FIRM_NAME)
1:1Participant organization data from Case Center migrates to a custom FIRM_NAME merge field in Mailchimp. This preserves firm or company affiliation for segmentation without requiring a separate CRM object in Mailchimp. The FIRM_NAME field can be used to filter audiences by organization, to target specific firms in multi‑firm matters, and to enrich email content with personalized firm references during campaigns.
Thomson Reuters Case Center
Phone Number
Mailchimp
Phone
1:1Direct map of participant phone numbers to Mailchimp's standard phone merge field. Mailchimp uses phone for SMS campaigns if the audience has SMS marketing enabled — we preserve the field regardless of immediate use. Having the phone number stored enables future SMS outreach, allows you to comply with contact preferences, and supports multi‑channel communication strategies even if SMS is not activated at migration time.
Thomson Reuters Case Center
Email Address
Mailchimp
Email Address
1:1Direct map — email is the primary key in Mailchimp. We validate email format during import and flag records with malformed addresses for manual correction before the migration commits. Because Mailchimp requires a unique email per contact, duplicates are merged and the resulting record retains combined tags, ensuring a clean, deliverable audience while preserving all role information.
Thomson Reuters Case Center
First Name / Last Name
Mailchimp
First Name / Last Name
1:1Direct map of Case Center participant first and last name fields to Mailchimp's standard FNAME and LNAME merge fields. If Case Center stores full name in a single field, we split on space and populate both Mailchimp fields. The split supports personalizing email greetings, and any missing name parts are left blank to avoid inaccurate addressing while still preserving the available name data.
Thomson Reuters Case Center
Document / Evidence File
Mailchimp
No Equivalent
1:1Case Center documents, PDFs, multimedia files, and evidence attachments have no Mailchimp equivalent. These are preserved as downloadable exports from Case Center and must be manually organized or stored in a document management system separate from Mailchimp. The export includes a manifest with file paths, case associations, and original upload dates, allowing your team to reconstruct the document hierarchy in a DMS or archive solution of your choice.
Thomson Reuters Case Center
Hearing Record
Mailchimp
No Equivalent
1:1Hearing schedules, virtual hearing links, and hearing-specific notes in Case Center have no Mailchimp equivalent. These remain in Case Center or are exported as reference documents — they do not map to Mailchimp campaigns or automations. The export is provided as a CSV file containing hearing date, time, type, and join URLs, so your team can manually communicate updates or build external calendar integrations as needed.
Thomson Reuters Case Center
Annotation / Note on Document
Mailchimp
No Equivalent
1:1Participant-added annotations and notes on case documents are Case Center-specific metadata with no Mailchimp equivalent. If these notes contain contact-relevant information, we extract it separately during the participant record export. Extracted data is placed into a dedicated notes field or merge field, ensuring that any relevant context (e.g., preferred contact method or special instructions) is preserved in Mailchimp for follow‑up actions.
Thomson Reuters Case Center
Access Permission Record
Mailchimp
No Equivalent
1:1Case Center's role-based access controls (time-restricted, file-restricted, redacted views) are legal-proceeding governance features with no Mailchimp equivalent. Mailchimp's subscriber status (subscribed/unsubscribed) governs email permissions but does not replicate case-level access hierarchies. After migration, you can use tags to denote participant roles, while case-specific viewing permissions remain managed in Case Center or a related legal platform.
Thomson Reuters Case Center
Case Status
Mailchimp
Tag (CASE_STATUS)
1:1Active, Pending, Closed case status from Case Center becomes a CASE_STATUS tag on Mailchimp contacts. This allows segmentation by case status for communications targeting participants in active versus closed matters. You can build Mailchimp segments that filter on CASE_STATUS to send case‑update newsletters to active participants, closure notices to closed‑case contacts, and status‑change alerts as cases progress.

Migration approach
Audit Case Center participant records and export schema
We connect to Case Center via its API using scoped read access and pull a full export of all participant records across active and recent cases. We document the field structure — standard fields (name, email, phone, role type) and any custom participant fields your firm has configured. We also export the case-level metadata (case number, case name, court, status, filing date) that will become merge field values. This audit identifies data quality issues (missing emails, malformed addresses) before we build the import map and flags any custom fields that need merge field creation in Mailchimp.
Design Mailchimp audience schema and merge field structure
Before contacts load, we create the Mailchimp audience with the required standard fields (email, first name, last name, phone) and any custom merge fields identified in the audit (CASE_REF, FIRM_NAME, COURT_NAME, CASE_STATUS, etc.). We configure tags for role types and case status values based on the value-mapping plan. If your Mailchimp account is on a tier that requires upgrade for your contact volume, we surface this before proceeding so your team authorizes the tier change with Mailchimp directly.
Run sample migration with field-level diff on 100-500 contacts
We migrate a representative slice of participant records — spanning different role types, cases, and organizational units — into a test Mailchimp audience. We generate a field-level diff report showing exactly what landed in each Mailchimp field and tag, with any transformation applied (name splitting, role-to-tag mapping, merge field population). You review the diff to confirm role-type mapping, duplicate handling, and merge field completeness before we commit to the full run.
Execute full migration with duplicate merge and delta-pickup window
The full participant record set loads into the production Mailchimp audience. Duplicate emails (same address across multiple Case Center participant records) merge into a single Mailchimp contact with combined tags. A delta-pickup window of 24-48 hours captures any new participant records created in Case Center during cutover — we re-query the API and import net-new contacts before closing the migration. We export the Case Center document file manifest separately for your manual document disposition. An audit log records every import operation, and one-click rollback is available if the audience needs to be reset and re-imported.
Deliver migration report and rebuild reference for Mailchimp workflows
We deliver a migration completion report: contact count by tag, merge field population rates, duplicate merge summary, and any records that failed validation (bad email format, missing required fields). We also export your Case Center workflow definitions as a text reference document so your Mailchimp admin can rebuild email campaign automations and communication sequences in Mailchimp based on the participant roles and case statuses now tracked in tags and merge fields. Case Center automations, hearing notifications, and evidence-handling workflows do not migrate — they must be rebuilt in Mailchimp or retained in Case Center as applicable.
