Overview
Casepeer is a legal practice management system built for personal injury firms — it organizes clients, cases, medical records, statutes of limitations, insurance claims, and case pipeline stages. Mailchimp is an email marketing platform that organizes recipients as audience members with tags, segments, and merge fields. These platforms serve entirely different functions: Casepeer manages legal case lifecycle; Mailchimp manages marketing communication and subscriber relationships. The migration from Casepeer to Mailchimp is therefore a contact-export operation — we pull client contact records from Casepeer and load them as subscribers in Mailchimp, translating Casepeer's case-type labels into Mailchimp tags for segmentation. Case-specific data (case status, insurance carrier, adjuster info, medical providers, statute dates, settlement values) has no native equivalent in Mailchimp and is either omitted or preserved as merge fields or tags at your direction. Workflows, case assignments, calendar rules, document management, and billing integrations are Mailchimp-incompatible — those must be rebuilt manually in Mailchimp or handled separately. The migration mechanism uses Casepeer's API (scoped read access) and Mailchimp's Bulk Email Marketing API, with a sample migration run and field-level diff before the full load commits.

Object mapping
Each row shows how a CASEpeer 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.
CASEpeer
Contact (Client)
Mailchimp
Audience Member
1:1Every Casepeer Contact (client) becomes a Mailchimp Audience Member. Email address is the unique identifier — contacts without email addresses cannot be added to Mailchimp and are flagged as exceptions before migration. First name, last name, phone, and address fields map to Mailchimp merge fields FNAME, LNAME, PHONE, and ADDRESS respectively.
CASEpeer
Contact.email
Mailchimp
Audience Member (Email Address)
1:1Email address is the primary key in Mailchimp. Casepeer contacts with duplicate email addresses are merged or flagged per your preferred rule (most-recently-modified wins). Contacts with missing or invalid email addresses are excluded and listed in the exception report for review and correction.
CASEpeer
Contact.firstname + Contact.lastname
Mailchimp
Merge Fields FNAME + LNAME
1:1Casepeer first and last name fields populate Mailchimp's standard FNAME and LNAME merge fields. Salutations and suffixes (Jr., III) stored in a separate Casepeer field map to a custom merge field SUFFIX__c if present. This ensures accurate personalization and proper formal address usage in Mailchimp email campaigns.
CASEpeer
Contact.phone
Mailchimp
Merge Field PHONE
1:1Phone numbers transfer to Mailchimp's PHONE merge field. Casepeer stores phone in multiple formats (with/without country code); we normalize to E.164 format before loading. Mobile and office numbers stored in separate Casepeer fields merge into a single PHONE field or split into MOBILE + OFFICE custom merge fields.
CASEpeer
Contact.address fields
Mailchimp
Merge Fields ADDRESS
1:1Casepeer stores street, city, state, zip, and country as separate fields. Mailchimp's ADDRESS merge field expects a structured format with addr1, addr2, city, state, zip, country. We concatenate and split Casepeer's address components into Mailchimp's structured format during load to ensure proper geocoding and deliverability.
CASEpeer
Case.type (case_type)
Mailchimp
Audience Tag
1:1Casepeer's case_type values (e.g., Auto Accident, Slip and Fall, Medical Malpractice, Workers' Comp) become Mailchimp Tags on each subscriber. We map each case_type label to a corresponding tag name and apply all applicable tags during migration. Tags enable Mailchimp segmentation by practice area in your customer journeys.
CASEpeer
Case.stage (pipeline_status)
Mailchimp
Merge Field CASE_STATUS
1:1Casepeer's case pipeline stages (e.g., Intake, Under Investigation, Negotiation, Litigation, Settlement, Closed) map to a custom Mailchimp merge field CASE_STATUS__c as pick-list values. This field allows you to segment clients by case progress in Mailchimp campaigns without revealing case details.
CASEpeer
Contact.createdate
Mailchimp
Merge Field ORIGINAL_ENROLLMENT_DATE
1:1Mailchimp does not preserve original subscriber enrollment dates when contacts are added via API — the member-since date is set at import time. We store Casepeer's original contact create date in a custom merge field ORIGINAL_ENROLLMENT_DATE__c for reporting continuity and segmentation by client cohort.
CASEpeer
Contact.hs_object_id (internal ID)
Mailchimp
Merge Field SOURCE_SYSTEM_ID
1:1Casepeer's internal record ID is stored in Mailchimp as SOURCE_SYSTEM_ID__c on each subscriber. This enables delta-run de-duplication, rollback identification, and cross-referencing if you need to re-import or reconcile against Casepeer after go-live. It also supports audit trail documentation and compliance verification for future data integrity checks.
CASEpeer
Case.insurance_carrier
Mailchimp
Merge Field INSURANCE_CARRIER
1:1Insurance carrier information from Casepeer has no native Mailchimp equivalent. We create a custom merge field INSURANCE_CARRIER__c and populate it where present. This field is optional and may be excluded if your firm prefers not to store this data in a marketing platform.
CASEpeer
Case.referral_source
Mailchimp
Merge Field REFERRAL_SOURCE
1:1Casepeer's referral source field (e.g., Doctor referral, Internet search, Repeat client, Partner firm) migrates to a custom merge field REFERRAL_SOURCE__c. This is valuable for Mailchimp segmentation to personalize outreach based on how the client originally found the firm and to improve ad targeting and content relevance.
CASEpeer
Note (Case Note)
Mailchimp
No equivalent in Mailchimp
1:1Casepeer case notes contain attorney-client privileged content, case strategy, medical provider records, and adjuster communications. Mailchimp has no note or case-log functionality. These records are excluded from the Mailchimp migration entirely. We export them to a structured JSON file as part of the migration package for your records.
CASEpeer
Document / Attachment
Mailchimp
No equivalent in Mailchimp
1:1Casepeer stores case documents, medical records, and correspondence. Mailchimp's file management is limited to email attachment templates and image hosting. Documents are excluded from migration. If you need document links available in Mailchimp, we can add a URL merge field pointing to a secure document portal you designate.
CASEpeer
Case Workflow / Automation Rule
Mailchimp
Mailchimp Customer Journey
1:1Casepeer workflow rules (case-stage triggers, task generation, deadline rules) are legal-process logic with no equivalent in Mailchimp's email automation builder. These must be rebuilt manually in Mailchimp's Customer Journey editor. We provide a workflow audit export from Casepeer as a rebuild reference.
CASEpeer
Calendar Event / Statute of Limitation
Mailchimp
No equivalent in Mailchimp
1:1Casepeer's calendar events and statute of limitations dates are legal calendaring data with no Mailchimp equivalent. Mailchimp's automation can trigger on subscriber date fields (birthday, anniversary), but legal deadlines are not appropriate for a marketing platform. These remain in Casepeer or your chosen legal calendar system.

Migration approach
Audit Casepeer contact records and design Mailchimp merge field schema
FlitStack AI connects to Casepeer via scoped API read access to enumerate all contact records, case-type labels, custom field definitions, and referral source values. We generate a schema report showing which fields have data, how many distinct case_type values exist, and how many contacts lack email addresses. Based on this audit, we design the Mailchimp merge field schema — creating custom fields for case_status, referral_source, insurance_carrier, and other case-specific data you want available in Mailchimp. You approve the schema before we proceed.
Resolve duplicate email addresses and contact exclusion rules
We identify all contacts sharing an email address and apply your deduplication rule (most-recently-modified wins, or first-created wins). Contacts without valid email addresses are excluded from the Mailchimp load and listed in the exception report. If you have contacts who have unsubscribed from marketing in Casepeer, we load them with Mailchimp suppressed (unsubscribed) status to preserve their preference. We surface the full exception list for your review before the sample migration runs.
Map case_type values to Mailchimp tags and create tag taxonomy
We enumerate all Casepeer case_type values across your records and map each to a corresponding Mailchimp tag. Tags are the primary segmentation tool in Mailchimp — you can create customer journeys that trigger when a subscriber has a specific tag (e.g., 'Auto Accident' or 'Medical Malpractice'). We deliver a tag taxonomy document showing your Casepeer case types and the Mailchimp tags they'll generate. You can rename, consolidate, or add tags before the migration runs.
Run a sample migration with field-level diff against a representative slice
We migrate a representative slice of 100–300 contacts (spanning multiple case types and statuses) into your Mailchimp audience and generate a field-level diff. You verify that merge fields populated correctly, tags applied as expected, and contacts landed in the right audience. The sample run identifies any missing custom fields, bad data patterns (malformed emails, missing required fields), or unexpected value mappings before the full migration commits. You approve the sample before we proceed.
Execute full migration with delta-pickup window and audit log
The full contact load runs against your Mailchimp audience via the Bulk Email Marketing API. A delta-pickup window (24–48 hours after initial load) captures any Casepeer contacts created or modified during the migration window. FlitStack AI generates an audit log listing every record loaded, every tag applied, every merge field populated, and every exception encountered. One-click rollback is available if the migration produces unexpected results — this reverts the Mailchimp audience to its pre-migration state. We deliver the audit log, exception report, and workflow export for your rebuild reference.
