Overview
Legal Case Tracker and Mailchimp serve fundamentally different purposes: Legal Case Tracker is a practice management system built for law firms to manage cases, clients, documents, time tracking, and billing. Mailchimp is an email marketing platform built for audience segmentation, campaign delivery, and marketing automation. The only meaningful data overlap is contact and client information — names, email addresses, phone numbers, and any custom fields that describe subscriber attributes rather than legal case specifics. FlitStack AI extracts contacts from Legal Case Tracker via its API or export endpoints, normalizes field names to Mailchimp's subscriber schema (First Name, Last Name, Email, Phone, and custom merge fields), and bulk-imports into your Mailchimp audience. Case records, matter data, documents, time entries, expenses, and billing information have no equivalent in Mailchimp — those records do not migrate and must remain in Legal Case Tracker or a successor legal practice management system. We use Mailchimp's native import API with batch processing to handle large contact lists, apply deduplication rules, and preserve original create dates as Mailchimp merge fields for continuity. Your team continues working in Legal Case Tracker during the migration; we use scoped read access and run a delta pickup window at cutover to capture any contact changes made during the transition.
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 Legal Case Tracker 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.
Legal Case Tracker
Contact / Client
Mailchimp
Subscriber
1:1Legal Case Tracker stores clients and contacts as the primary contact object. These map directly to Mailchimp subscribers. Each contact record carries a first name, last name, email address, phone number, and role association to one or more cases. Mailchimp requires a valid email address for every subscriber — contacts without emails are flagged before migration and do not import.
Legal Case Tracker
Contact Email Address
Mailchimp
Subscriber Email Address
1:1The email address field from Legal Case Tracker contacts maps 1:1 to Mailchimp's email address field. This is the primary key for Mailchimp subscribers. Deduplication is applied: if the same email appears across multiple Legal Case Tracker contacts (e.g., a shared firm email), the system creates one subscriber record and merges contact associations as tags.
Legal Case Tracker
Contact First Name
Mailchimp
Subscriber First Name (FNAME merge field)
1:1First name from Legal Case Tracker maps to Mailchimp's FNAME merge field. If Legal Case Tracker stores full names in a single field, we parse and split into first/last before import. Blank first names are preserved as empty strings and do not block import.
Legal Case Tracker
Contact Last Name
Mailchimp
Subscriber Last Name (LNAME merge field)
1:1Last name from Legal Case Tracker maps to Mailchimp's LNAME merge field. Same parsing and handling rules apply as with first name. Law firms sometimes use 'RE: Client' or similar conventions as last name fields for organization contacts — we flag these for manual review before import.
Legal Case Tracker
Contact Phone Number
Mailchimp
Subscriber Phone (PHONE merge field)
1:1Phone numbers from Legal Case Tracker contact records map to Mailchimp's PHONE merge field. We validate phone number formats and apply E.164 normalization where possible. Mailchimp supports SMS marketing with phone consent — if your Legal Case Tracker tracks SMS opt-in status, we map that to Mailchimp's SMS consent field.
Legal Case Tracker
Contact Address Fields
Mailchimp
Subscriber Address (ADDRESS merge field)
1:1Legal Case Tracker stores address components separately (street, city, state/province, postal code, country). Mailchimp's ADDRESS merge field is a compound field. We concatenate these into Mailchimp's structured address format. If Legal Case Tracker stores a single address string, we parse it by component and flag any ambiguous extractions for review.
Legal Case Tracker
Contact Custom Field: Client Type
Mailchimp
Mailchimp Tag or Merge Field
1:1If Legal Case Tracker uses a client type field (e.g., 'Plaintiff', 'Defendant', 'Corporate Client', 'Prospective Client'), we map these to Mailchimp tags or a custom merge field. Tags are preferred for segmentation since Mailchimp's tag model maps naturally to client type categories. The specific value mapping is defined during the mapping phase based on the actual values in your Legal Case Tracker instance.
Legal Case Tracker
Contact Custom Field: Referred By
Mailchimp
Mailchimp Merge Field
1:1If Legal Case Tracker tracks referral source as a contact property, we create a custom merge field in Mailchimp (e.g., REFERRAL_SOURCE) and map the values directly. Mailchimp allows unlimited custom merge fields — this field is available for segmentation in campaigns and automations.
Legal Case Tracker
Contact Status / Active Flag
Mailchimp
Mailchimp Subscriber Status
1:1Legal Case Tracker may mark contacts as 'Active', 'Inactive', 'Closed', or 'Archived'. We map active contacts to Mailchimp 'subscribed' status and inactive contacts to 'archived' or 'unsubscribed' based on your preference. You control the mapping table before the migration runs — archived Mailchimp contacts retain data but do not receive campaigns.
Legal Case Tracker
Case / Matter Record
Mailchimp
No Equivalent in Mailchimp
1:1Legal Case Tracker case and matter records have no equivalent in Mailchimp's email marketing model. Case names, case numbers, case status, assigned attorneys, opposing parties, and case-specific notes are legal case management data that does not belong in an email marketing platform. We do not migrate these records. You must retain them in Legal Case Tracker or move them to a successor legal practice management system.
Legal Case Tracker
Document / File Attachment
Mailchimp
No Equivalent in Mailchimp
1:1Documents and file attachments stored in Legal Case Tracker case records have no Mailchimp equivalent. Mailchimp supports image hosting for email templates and campaign assets, but case documents, contracts, correspondence, and evidence files must remain in a document management system. We do not migrate these records.
Legal Case Tracker
Time Entry / Billing Record
Mailchimp
No Equivalent in Mailchimp
1:1Time entries, expenses, invoices, and billing records in Legal Case Tracker are financial and practice management data with no email marketing purpose. These records are excluded from the migration. They must remain in Legal Case Tracker or be transferred to an accounting or practice management platform.
Legal Case Tracker
Calendar / Deadline
Mailchimp
No Equivalent in Mailchimp
1:1Legal Case Tracker calendars, hearing dates, filing deadlines, and task schedules have no equivalent in Mailchimp. We do not migrate these records. If you need deadline reminders or client appointment notifications, Mailchimp's automation features can be rebuilt separately using contact data — but the source calendar data does not transfer.
Legal Case Tracker
Contact Role on Case
Mailchimp
Mailchimp Tag
1:1Legal Case Tracker associates contacts with cases using roles such as 'Client', 'Opposing Counsel', 'Witness', 'Expert', 'Insurance Adjuster'. We extract these role associations and apply them as tags in Mailchimp. For example, a contact with the role 'Client' on three matters receives the tag 'Client'. This allows you to segment your Mailchimp audience by legal role if needed for firm communications.

Migration approach
Audit Legal Case Tracker contacts and define migration scope
We connect to Legal Case Tracker via read-only API access and pull a full export of contact records. We analyze the data for completeness — missing emails, duplicate records, ambiguous name fields, and custom property coverage. We produce a scoping report listing: total contact count, email coverage rate, custom field inventory, and recommended exclusion criteria (e.g., inactive contacts, contacts without marketing consent). Your team approves the scope before we proceed to mapping.
Build field mapping table and deduplication rules
Based on the scoping report, we define the field mapping table covering all standard contact fields (name, email, phone, address) and any custom fields that map to Mailchimp merge fields or tags. We define deduplication rules — which record wins when duplicate emails appear — and your team confirms the contact status mapping table (Active → Subscribed, Inactive → Archived, etc.). We configure Mailchimp merge fields and tags in your target audience before any data loads.
Run sample migration and generate field-level diff
A representative slice of contacts — typically 100–500 records spanning different case roles, client types, and geographic regions — migrates first into your Mailchimp test audience. We generate a field-level diff comparing the Legal Case Tracker source values against the Mailchimp subscriber records so you can verify name parsing, address formatting, tag application, and status mapping before the full run commits.
Execute full migration with scoped read access and delta pickup
The full contact list migrates into your production Mailchimp audience using batch API calls. Your team continues working in Legal Case Tracker during the migration — we use scoped read-only access. A delta pickup window (typically 24–48 hours) captures any contacts created or modified during the cutover. We apply deduplication against the migrated set to avoid duplicates from the delta window. The audit log records every operation, and one-click rollback is available if reconciliation finds unexpected discrepancies.
Validate, deliver export reference, and document what did not migrate
Post-migration, we run validation checks: subscriber count matches source contact count, email coverage matches the scope, tags are applied per case-role associations, and status mapping matches your approved table. We deliver a migration summary report listing all migrated contacts, excluded contacts (with reasons), and unmapped objects (cases, documents, billing, etc.). We also deliver the Legal Case Tracker workflow definitions as a reference document for your team.
