Overview
Legistify stores legal operations data — matters, contracts, parties, documents, clauses, and compliance items — with party contact information embedded in matter records. Mailchimp organizes contacts into audiences, using merge fields for custom properties, tags for categorization, and segments for targeted sends. These platforms have fundamentally different data models: Legistify is legal-workflow-centric while Mailchimp is contact-communication-centric. The migration extracts contact and party records from Legistify matters, preserving email addresses, phone numbers, organization names, and any custom contact properties as Mailchimp merge fields. Legal-specific data like matter status, contract values, clause references, and compliance records have no Mailchimp equivalent and must be handled as manual exports or documented for reference. We sequence the migration to resolve contact deduplication first, then bulk-import into your Mailchimp audience with tag-based organization. Workflows, automations, templates, and legal-specific fields do not migrate — they require manual rebuild or replacement in Mailchimp. The migration also includes a comprehensive validation pass that compares source and destination field values, ensuring data integrity before your team begins using Mailchimp for outreach.

Object mapping
Each row shows how a Legistify 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.
Legistify
Matter (Case/Contract)
Mailchimp
Audience
1:1Legistify matters have no Mailchimp equivalent. The matter record itself does not migrate — only the parties and contacts embedded in the matter are extracted. Matter identifiers are stored as reference tags on contacts for traceability. Matter type, status, and region are also captured as separate tags to allow segmentation by practice area or jurisdiction, preserving the organizational context without reconstructing a full matter record.
Legistify
Party (Contact/Organization)
Mailchimp
Contact (Subscriber)
1:1Party records with email addresses map directly to Mailchimp contacts. Each party becomes a subscriber in the target audience. Party type (individual, corporate) is stored as a tag rather than a separate field. Tag names use the prefix PTYPE_ to keep the taxonomy organized and avoid collisions with other labels.
Legistify
Individual Party
Mailchimp
Contact (Subscriber)
1:1Individual parties with first name, last name, email, and phone map to Mailchimp contacts with those merge fields populated. Organization affiliation from the matter is stored as the COMPANY merge field or as a tag. If a party has multiple organization affiliations, each is added as a separate tag to preserve the full relationship without overloading the COMPANY field.
Legistify
Corporate Party (Organization)
Mailchimp
Contact (Subscriber) + Tag
many:1Corporate parties without a named individual contact are represented as contacts with the organization name in the COMPANY merge field. A 'Corporate Party' tag identifies these records. If no email exists for a corporate party, the record is flagged for manual review.
Legistify
Matter Property (Custom Field)
Mailchimp
Merge Field
1:1Legistify custom matter properties migrate as Mailchimp merge fields. Text properties under 255 characters map directly; longer text properties are truncated or stored as document reference links. Pick-list values become merge field options. When a property exceeds the 255-character limit, the full text is exported to a CSV with a unique reference ID, and the merge field contains the truncated snippet for quick reference.
Legistify
Clause Library Reference
Mailchimp
Tag
1:1Legistify clause library references have no Mailchimp equivalent. Standard clause types (indemnification, limitation of liability, etc.) are stored as tags on the contact if the clause relates to a party. Full clause text is not migrated. Tag names follow a CL_ prefix followed by the clause type, for example CL_INDEMNIFICATION, to make them readily identifiable in the Mailchimp audience.
Legistify
Compliance Item
Mailchimp
Tag
1:1Compliance records in Legistify track regulatory adherence and deadline dates. These do not map to Mailchimp contacts directly. Compliance status tags (GDPR, SOC2, etc.) may be applied if relevant to contact communication preferences. If a compliance item has an associated deadline, the date is stored in a custom merge field called COMPLIANCE_DEADLINE for future segmentation and reminder workflows.
Legistify
Document (Attached File)
Mailchimp
External Reference
1:1Legistify documents attached to matters do not migrate to Mailchimp. Mailchimp supports file attachments in campaigns but not document management. Document metadata (filename, upload date, type) is exported to a reference CSV for manual handling. The CSV includes the original Legistify document ID and a link to the source file, enabling your team to reattach documents in a document management system if needed.
Legistify
Audit Log Entry
Mailchimp
External Export
1:1Legistify audit logs track matter changes, user actions, and system events. Mailchimp does not have an audit log equivalent for contacts. Audit log data is exported to a separate CSV file for compliance retention. The exported CSV includes timestamps, user IDs, action types, affected matter IDs, and the state of each record at the time of the event, providing a full audit trail.
Legistify
Matter Type / Practice Area
Mailchimp
Tag
1:1Legistify matter types (litigation, contracts, compliance, employment) map to Mailchimp tags on the associated party contacts. This allows segmentation by practice area in Mailchimp campaigns without losing organizational context. Tag names use the prefix MTYPE_ followed by the matter type, for example MTYPE_LITIGATION, to keep the taxonomy consistent and simple to filter.
Legistify
Party Role in Matter
Mailchimp
Tag
1:1Party roles (plaintiff, defendant, counterparty, vendor, client) from Legistify matter associations are stored as Mailchimp tags. Role values are mapped one-to-one to tag names for consistent labeling across contacts. If a contact has multiple roles across different matters, each role is applied as a separate tag, preserving the full role history without overwriting any existing tags.
Legistify
Matter Status
Mailchimp
Tag
1:1Legistify matter status values (active, pending, closed, on-hold) are mapped to Mailchimp tags on party contacts. This enables filtering contacts by matter status without creating separate audiences for each status. Tag names use the prefix MSTATUS_ to distinguish them from other tag categories, for example MSTATUS_ACTIVE, making it straightforward to build segments based on current matter state.

Migration approach
Extract party and contact records from Legistify matters via API
FlitStack AI connects to your Legistify instance using API credentials with read access. We extract all party records attached to matters, including individual contacts and corporate parties. The extraction pulls email addresses, phone numbers, organization names, addresses, and any custom party properties. We also capture matter-party associations to build the tag taxonomy. Party records without email addresses are flagged separately for your team to resolve before migration — Mailchimp requires an email for every subscriber.
Deduplicate contacts and resolve multi-matter associations
Legistify parties can appear across multiple matters with the same or different email addresses. We deduplicate contacts by email address, keeping the most recently updated record. For parties with multiple matter associations, we apply matter-type tags and matter-ID merge fields to preserve context. The deduplication report shows which contacts were merged, which had conflicting data, and which remain flagged for manual review.
Map Legistify properties to Mailchimp merge fields and tags
We map Legistify party fields to Mailchimp standard merge fields (FNAME, LNAME, PHONE, COMPANY, ADDRESS fields). Custom Legistify matter properties attached to parties become Mailchimp custom merge fields. Text properties under 255 characters map directly; longer properties are truncated with full text exported to a reference CSV. Matter type, status, region, and assigned attorney map to Mailchimp tags for segmentation. We validate merge field names against Mailchimp's allowed character set before the import.
Run sample migration with field-level verification
A representative sample of 100–500 contacts migrates first into your Mailchimp audience. We verify merge field population, tag application, and address data formatting. The field-level diff compares Legistify source values against Mailchimp subscriber records so you can confirm mapping accuracy before the full run. Any merge field truncation warnings or tag-application errors surface here. Your team approves the sample before we proceed to full migration.
Execute full migration with delta-pickup window
The full contact set migrates into your Mailchimp audience. A 24–48 hour delta-pickup window captures any Legistify records created or modified during the cutover window. We apply a final deduplication pass after delta-pickup to prevent duplicates from in-flight changes. The audit log records every operation. If reconciliation reveals discrepancies, one-click rollback reverts the audience to its pre-migration state. We deliver the final export CSVs for audit logs, clause libraries, and matter-document metadata as separate files for compliance retention.
