Overview
Outlaw Practice stores client contacts with legal-CRM attributes: matter numbers, practice areas, billing rates, case statuses, and attorney assignments. Mailchimp stores contacts as email subscribers inside an audience, with standard merge fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS) plus custom merge fields and tags. The migration extracts Outlaw Practice clients and companies, transforms legal-CRM attributes into Mailchimp merge fields and tags, and loads the resulting audience into Mailchimp. Outlaw Practice case management, billing records, documents, and calendar data have no native Mailchimp equivalent — those stay in Outlaw Practice or get exported as reference CSVs for rebuild use. Workflows, automations, and email sequences built in Outlaw Practice cannot migrate; they must be rebuilt in Mailchimp using the migrated contact data as the foundation. FlitStack sequences the export through Outlaw's read-only API, transforms field names and value sets, creates the Mailchimp audience structure (merge fields and tag groups) before import, runs a sample migration, then executes the full load with a delta-pickup window to capture any contacts added during cutover.
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 Outlaw Practice 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.
Outlaw Practice
Client / Contact
Mailchimp
Subscriber / Audience Member
1:1Outlaw Practice clients map to Mailchimp subscribers. The client's email address is the primary key — contacts without a valid email address cannot be imported into Mailchimp and are flagged before migration. FlitStack validates email deliverability against Mailchimp's syntax and domain checks before insert.
Outlaw Practice
Company / Firm Record
Mailchimp
Company Merge Field on Subscriber
1:1Outlaw Practice firm/company records map to Mailchimp's built-in COMPANY merge field on each subscriber. If a client is associated with multiple firms in Outlaw (rare), the primary firm maps to COMPANY and secondary associations are stored as tags for reference.
Outlaw Practice
Case / Matter
Mailchimp
Tag on Subscriber + Matter_Number Merge Field
1:1Outlaw Practice cases have no direct Mailchimp equivalent — Mailchimp has no case or matter object. FlitStack maps the case status (active, pending, closed, archived) to a Mailchimp tag group called Case_Status so each contact carries their matter's current status. Matter number maps to a custom merge field Matter_Number__c for reference.
Outlaw Practice
Billing / Invoice Record
Mailchimp
CSV Export Reference File
1:1Outlaw Practice billing records (line items, hours, rates, invoice IDs) have no Mailchimp equivalent. FlitStack exports these as a separate reference CSV tied to contacts by email address. Firms can use the export to rebuild invoice narratives inside Mailchimp campaigns or keep billing in Outlaw Practice.
Outlaw Practice
Document / Attachment
Mailchimp
CSV Export Reference File
1:1Outlaw Practice document and attachment storage does not map to Mailchimp. File names, document types, and storage paths are exported as a reference CSV linked to client email for audit trail purposes. Actual file re-hosting is outside the Mailchimp audience model.
Outlaw Practice
Calendar / Court Date
Mailchimp
CSV Export Reference File
1:1Court dates and calendar events in Outlaw Practice have no Mailchimp equivalent. FlitStack exports calendar entries as a reference CSV keyed to client email so firms can reconstruct event-triggered email sequences such as hearing reminders, filing deadline alerts, and client meeting follow-ups within Mailchimp after migration is complete.
Outlaw Practice
Practice Area
Mailchimp
Tag Group + Custom Merge Field
1:1Practice area in Outlaw Practice (Family Law, Estate Planning, Criminal Defense, etc.) maps to a Mailchimp tag group called Practice_Area. Each contact receives one practice-area tag based on their primary matter. A custom merge field Practice_Area__c stores the same value as a field for segmentation use in Mailchimp reports.
Outlaw Practice
Client Status
Mailchimp
Tag Group + Custom Merge Field
1:1Outlaw Practice client status values (active, inactive, prospective, archived) map one-to-one as tags in the Client_Status tag group. Each contact receives a status tag reflecting their current relationship with the firm. A custom merge field Client_Status__c stores the same value for conditional content use in Mailchimp campaigns.
Outlaw Practice
Custom Fields (bar_number, billing_rate)
Mailchimp
Custom Merge Fields
1:1Outlaw Practice custom fields bar_number and billing_rate have no Mailchimp standard equivalent. FlitStack creates custom merge fields BAR_NUMBER__c (text, max 255 chars) and BILLING_RATE__c (text, max 255 chars) in the Mailchimp audience before import. billing_rate is stored as text because Mailchimp merge fields do not support currency formatting natively.
Outlaw Practice
Source Tracking
Mailchimp
Tag Group + Custom Merge Field
1:1Outlaw Practice tracks how clients were acquired (referral, website inquiry, advertising campaign, etc.). These source values become a Mailchimp tag group called Client_Source, with one source tag per contact. A custom merge field Client_Source__c stores the same value for acquisition-channel segmentation in Mailchimp reporting dashboards.

Migration approach
Extract client contacts from Outlaw Practice via read-only API
FlitStack connects to Outlaw Practice using read-only API credentials, pulling all client and company records including custom fields (practice_area, bar_number, billing_rate, billable_status), matter associations, and system timestamps. The team keeps working in Outlaw Practice throughout — the integration only reads. A data inventory report is generated showing field coverage, email validity rates, and the count of records with and without each custom field.
Design Mailchimp audience structure: merge fields and tag groups
Before any data is loaded, FlitStack creates the Mailchimp audience and builds the merge field schema based on the extracted Outlaw Practice fields. Custom merge fields (Practice_Area__c, Bar_Number__c, Billing_Rate__c, Attorney__c, Matter_Number__c, etc.) are created in the Mailchimp audience. Tag groups for Case_Status, Practice_Area, Client_Status, Client_Source, and Phone_Type are set up so contacts land in the correct segmentation immediately on import.
Transform and map contact data with value-set and character-limit handling
Outlaw Practice field values are transformed to match Mailchimp's requirements: email format preferences mapped to EMAIL_TYPE, phone numbers validated and formatted, billing rates stored as text strings, and practice-area values mapped to the tag-group taxonomy. Client notes exceeding 255 characters are truncated with a [TRUNCATED] flag appended, and the full value is written to a reference CSV. The transformation log documents every truncation and value-mapping decision for review before the import runs.
Run sample migration of 100–500 contacts and verify audience structure
A representative subset of Outlaw Practice contacts (spanning active, inactive, and prospective clients across multiple practice areas) is imported into Mailchimp. FlitStack generates a field-level verification report comparing source values against the Mailchimp subscriber records: merge field values, tag assignments, email address validity, and case-status tag coverage are checked. Any mapping errors are corrected before the full run is scheduled.
Execute full migration with delta-pickup window and post-import validation
The complete Outlaw Practice contact list is imported into Mailchimp. A delta-pickup window (typically 24–48 hours) captures any new contacts created in Outlaw Practice during the migration window. After import, FlitStack runs post-import validation: total subscriber count against source record count, email bounce rate check, tag coverage report, and merge field population rate. A delivery test campaign is sent to a small internal list to confirm inbox placement before the firm launches its first Mailchimp campaign.
