Overview
Jarvis Legal is a legal practice management platform centered on matters, time tracking, billing, and client relationship management. Its data model revolves around contacts linked to matters, with extensive custom fields per client record, billing histories, and document attachments. Mailchimp is an email marketing platform organized around audiences, subscribers, tags, and campaign automation. The two systems share only one data primitive in common: contact records with name, email, phone, and address fields. FlitStack AI migrates contacts from Jarvis Legal to Mailchimp audience members, mapping standard fields directly and converting Jarvis custom properties to Mailchimp merge fields. Legal-specific data such as matter records, billing invoices, trust accounting, document storage, and workflow automations have no Mailchimp equivalent and cannot migrate. Client matter status can be preserved as a tag or merge field so your team knows which contacts have open matters versus closed matters when running marketing campaigns. We use scoped read access on Jarvis Legal to extract contact data, apply field mapping, and push records to Mailchimp via the Mailchimp API. A sample migration with field-level diff runs first so you can verify merge field accuracy before the full contact load commits.
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 Jarvis Legal 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.
Jarvis Legal
Contact / Client
Mailchimp
Audience Member
1:1JARVIS Legal client contact records map directly to Mailchimp audience members. Email address is the primary key for matching and serves as the unique identifier for upsert operations. All standard fields such as name, phone, and address are mapped as merge fields, and any contacts without email addresses are flagged for manual review because Mailchimp requires a valid email for audience membership.
Jarvis Legal
Contact Custom Fields
Mailchimp
Merge Field
1:1Jarvis Legal custom fields per contact record (such as practice area, referring attorney, matter type) are read from the Jarvis API and created as Mailchimp merge fields. Each custom field in Jarvis becomes one merge field in the target audience, with field type mapped to Mailchimp's supported types: text, number, date, address, or phone.
Jarvis Legal
Matter Status
Mailchimp
Tag
1:1Matter open/closed status from Jarvis Legal is translated into Mailchimp tags. Open matters receive the 'Active Client' tag, while closed matters receive the 'Former Client' tag. This tagging strategy enables you to segment your Mailchimp audience by client lifecycle stage, allowing targeted email campaigns such as matter‑close nurture sequences, re‑engagement messages to former clients, and reporting on audience health by status.
Jarvis Legal
Contact Tags / Labels
Mailchimp
Mailchimp Tag
1:1JARVIS Legal contact tags (such as 'VIP', 'Referral Source', or 'Pro Bono') migrate as Mailchimp tags. Tags are additive, meaning a single contact can retain multiple tags from Jarvis Legal. We normalize tag names during migration to deduplicate identical labels and prevent Mailchimp tag inflation, while preserving the full set of labels for segmentation and targeted campaign targeting.
Jarvis Legal
Contact Address
Mailchimp
Merge Field (Address type)
1:1JARVIS Legal address fields (street, city, state, postal code, country) map to Mailchimp's native address merge fields. If JARVIS stores address as a single concatenated string, FlitStack AI parses it into its component parts before loading to Mailchimp's structured address merge fields, ensuring geolocation and address validation features work correctly in Mailchimp.
Jarvis Legal
Phone Number
Mailchimp
Merge Field (Phone type)
1:1Phone numbers from Jarvis Legal contact records migrate as Mailchimp phone‑type merge fields. This preserves the contact's primary phone for reference and enables SMS marketing integration if your Mailchimp plan supports it. FlitStack AI also validates phone number formatting during migration to ensure consistency with Mailchimp's required format for SMS campaigns.
Jarvis Legal
Matter / Case Record
Mailchimp
No Equivalent
1:1Matter records, case descriptions, court dates, opposing counsel, and legal strategy notes have no Mailchimp equivalent and are therefore excluded from the migration. FlitStack AI exports these fields as a structured CSV from Jarvis Legal, preserving all relevant matter details for archival, compliance, or future import into a practice‑management system. Matter data does not enter Mailchimp.
Jarvis Legal
Billing / Invoice Record
Mailchimp
No Equivalent
1:1Invoice records, trust account balances, and billing histories from Jarvis Legal are financial data with no email‑marketing analog and are excluded from the Mailchimp migration. FlitStack AI exports these records as a separate CSV, capturing invoice numbers, amounts, dates, and trust‑account activity for import into your accounting or practice‑management system. This preserves your financial record set independently of Mailchimp.
Jarvis Legal
Document / Attachment
Mailchimp
No Equivalent
1:1Documents stored in Jarvis Legal (contracts, pleadings, correspondence PDFs) cannot migrate to Mailchimp, which supports only inline image embeds in campaigns. We export a document inventory list. Documents remain in Jarvis Legal or can be migrated to a dedicated document management system.
Jarvis Legal
Workflow / Automation
Mailchimp
No Equivalent
1:1Jarvis Legal workflow automations (task routing, deadline alerts, document generation triggers) are legal practice logic with no structural equivalent in Mailchimp. Mailchimp's customer journeys serve a different purpose. We provide a workflow definition export from Jarvis Legal for your team to reference when rebuilding email sequences.

Migration approach
Audit Jarvis Legal contacts and custom fields
FlitStack AI connects to Jarvis Legal via scoped read access and extracts all contact records and associated custom field definitions. We count records, identify missing email addresses, inventory custom property names and pick-list values, and flag any contacts linked to multiple matters. This audit produces a field mapping plan that names every Jarvis field and its corresponding Mailchimp destination (merge field, tag, or exclusion). The audit also surfaces duplicate contacts and contacts without email addresses for your team to resolve before migration.
Create Mailchimp merge fields from Jarvis custom properties
Before contacts load, FlitStack AI creates the Mailchimp merge fields needed to receive your custom property data. Each Jarvis Legal custom property becomes one Mailchimp merge field, with the type mapped to Mailchimp's supported formats (text, number, date, phone, or address). If your Jarvis setup exceeds Mailchimp's merge field limit, we prioritize fields by operational relevance and document the overflow for a follow-up migration pass.
Tag contacts by matter status and custom labels
Matter open/closed status and any custom client labels from Jarvis Legal are translated into Mailchimp tags during the load. Open matters receive the 'Active Client' tag; closed matters receive 'Former Client'. Referral sources, client tiers, and practice area labels also become Mailchimp tags for segmentation. Tags are additive — a contact can carry multiple tags reflecting its full profile from Jarvis Legal. We deduplicate tag names during loading to prevent Mailchimp tag bloat.
Run sample migration with field-level diff
A representative slice of 100–500 contacts migrates first, typically spanning a mix of individual clients, corporate contacts, active and closed matters, and contacts with the full range of custom properties. We generate a field-level diff between the Jarvis Legal source record and the resulting Mailchimp audience member so you can verify that every merge field populated correctly, tags applied as expected, and contacts without email were correctly excluded. You approve the sample before the full migration commits.
Execute full migration and delta pickup
The full contact list loads to Mailchimp via the Mailchimp API, with contacts upserted by email address to handle any existing audience members gracefully. A delta-pickup window of 24–48 hours captures any contacts added or modified in Jarvis Legal during the cutover window. FlitStack AI generates an audit log of every record loaded, including any that failed or were excluded, so your team has a complete reconciliation record. One-click rollback is available if the Mailchimp audience requires a restart.
