Overview
Moving from Jarvis CRM to Mailchimp is a scope-reduction migration, not a like-for-like CRM swap. Jarvis CRM is a FileMaker Pro-powered CRM, ERP, project management, and accounting platform with no published REST API. Mailchimp is a contact-centric email marketing platform with a REST API. The only objects that map cleanly are Contacts and Companies (mapped to Mailchimp audience members with company stored as a merge field or tag), Marketing Campaigns and Groups (mapped to Mailchimp Audiences and Tags), and email subscription status. Projects, Opportunities, Vendors, Purchase Orders, Time Entries, and ERP data have no Mailchimp equivalent and must be explicitly excluded or archived separately. We coordinate with the customer's FileMaker host to extract via FileMaker export scripts, clean and deduplicate contacts, and load via Mailchimp's REST API with batch chunking and idempotency keys. Workflows, automations, and FileMaker Pro custom scripts do not migrate; we deliver a written inventory for the customer's admin to evaluate what can be rebuilt in Mailchimp.

Object mapping
Each row shows how a Jarvis CRM 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 CRM
Contact
Mailchimp
Audience Member
1:1Jarvis Contacts map to Mailchimp Audience Members. The Contact's email address becomes the subscriber key (email_md5 hash used by Mailchimp's API). First name, last name, phone, address, and any standard fields map to Mailchimp merge fields (FNAME, LNAME, PHONE, ADDRESS). We extract Contact IDs and relationship fields from FileMaker to reconstruct any contact-to-company association during import. Subscription status (email opt-in) from Jarvis maps to Mailchimp's Marketing Permissions and Status fields. Duplicate emails detected during import are flagged for the customer's review before finalization.
Jarvis CRM
Company
Mailchimp
Audience Member (merge field or tag)
lossyJarvis Companies do not have a direct Mailchimp equivalent because Mailchimp does not have an Account or Company object separate from the audience member. We map Company by storing the company name in a custom merge field (COMPANY) on each related Audience Member. Alternatively, for organizations that want to segment by company, we map Company records to Mailchimp Tags applied to each Audience Member (one tag per unique company name). The customer chooses the strategy during scoping based on their reporting and segmentation needs.
Jarvis CRM
Marketing Campaign and Group
Mailchimp
Audience
1:1Jarvis Marketing Campaigns map to Mailchimp Audiences. We extract campaign metadata (campaign name, description, creation date, campaign type) and group memberships (which contacts are in which groups). Each Jarvis group becomes a Mailchimp Tag or Segment within the corresponding Audience. If the customer uses multiple Jarvis campaigns with different contact lists, we map each to a separate Mailchimp Audience. Campaign content and email templates from Jarvis require separate export and rebuild as Mailchimp templates because template code and design do not carry over in a data migration.
Jarvis CRM
Custom Properties (contact fields)
Mailchimp
Merge Fields
lossyJarvis custom contact fields identified during the FileMaker schema audit map to Mailchimp audience merge fields. We create each merge field in Mailchimp (type: text, number, date, or checkbox matching the source field type) before importing. Merge fields are audience-specific in Mailchimp, so each destination Audience must have its merge field definitions created independently if the customer maintains multiple Audiences. Fields with no meaningful destination mapping are flagged in the scope document for the customer's review.
Jarvis CRM
Opportunities
Mailchimp
Not migrated
lossyJarvis Opportunities (deal pipeline, stage, value, close date) have no Mailchimp equivalent. Mailchimp does not have an Opportunity, Deal, or Sales Pipeline object. We do not migrate Opportunities. If the customer needs to preserve Opportunity data, we export it as a CSV file for their records and recommend a separate CRM implementation. This is an explicit scope exclusion discussed during discovery.
Jarvis CRM
Projects
Mailchimp
Not migrated
lossyJarvis Projects (with Gantt data, tasks, assignees, and templates) have no Mailchimp equivalent. Mailchimp is not a project management platform. We do not migrate Projects. We export Project records as a separate CSV file if the customer wants an archival copy.
Jarvis CRM
Vendors and Purchase Orders
Mailchimp
Not migrated
lossyJarvis Vendor records and Purchase Orders (part of the ERP module) have no Mailchimp equivalent. Mailchimp does not support vendor management, purchasing, or accounting data. We do not migrate these objects. If the customer maintains QuickBooks Online integration with Jarvis, vendor and PO data may be accessible directly in QuickBooks Online as the system of record for accounting.
Jarvis CRM
Time Entries
Mailchimp
Not migrated
lossyJarvis Time Entries (billable and non-billable hours linked to projects, contacts, or vendors) have no Mailchimp equivalent. Time tracking is outside Mailchimp's scope. We do not migrate Time Entries. If time tracking is required, we recommend a separate time-tracking tool or CRM with native time entry.
Jarvis CRM
Attachments
Mailchimp
Not migrated
lossyFile attachments stored within the FileMaker instance (documents, images, PDFs linked to contacts or companies) cannot be imported into Mailchimp's audience data model. Mailchimp stores attachments as campaign assets (images in templates) but not as contact-level document repositories. We identify attachment storage paths during the FileMaker schema audit and export attachments as a separate file archive for the customer's records.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Jarvis CRM gotchas
No documented public API means migration requires FileMaker-native exports
FileMaker schema varies per deployment because the platform is fully customizable
Customizations are not included in base pricing and require separate engagement
Data relationships between FileMaker tables must be reconstructed manually
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Discovery and FileMaker access coordination
We audit the Jarvis FileMaker instance to identify which objects and fields are in use. We confirm data access permissions with the customer's FileMaker host and coordinate a schema export. We document every custom contact field, custom company field, and custom object identified in the deployment. We also analyze contact volume (for Mailchimp pricing), duplicate email rate, and the scope of ERP and project data that will be excluded from migration. The discovery output is a written migration scope, a FileMaker export plan, and a Mailchimp pricing estimate based on the contact volume.
FileMaker export and data extraction
We work with the customer's FileMaker host to export data from relevant tables: Contacts, Companies, Campaigns, Groups, and any custom contact fields. We extract primary keys and foreign keys to reconstruct relationships (contact-to-company associations, group memberships). If the Scarpetta Group has added custom export scripts, we use those; otherwise, we coordinate direct table exports. We export ERP and project objects as separate CSV archives for the customer's records, not as part of the Mailchimp migration scope.
Data cleansing and deduplication
We clean and normalize the extracted data before Mailchimp import. This includes standardizing phone number formats, address formatting, and date fields to match Mailchimp's merge field expectations. We run duplicate detection on email addresses and flag duplicates for customer resolution. We create the Mailchimp merge field definitions in the destination Audience before importing any contacts.
Mailchimp audience and merge field configuration
We create the Mailchimp Audience structure before importing data. This includes creating the Audience (or Audiences if multiple contact lists are being consolidated), creating merge field definitions for each mapped custom property, and setting up tags or segments for Jarvis Groups and Companies if those are being preserved. We configure Mailchimp's GDPR and marketing permission fields to match the opt-in status captured in Jarvis.
API-based contact import with batch chunking
We import Contacts into Mailchimp via Mailchimp's REST API using batch operations. We chunk large imports to stay within Mailchimp's API rate limits (200 requests per minute for most endpoints, with batch endpoints allowing up to 5,000 members per request). We use idempotency keys to prevent duplicate imports on retry. Each import batch emits a reconciliation report (contacts imported, errors, duplicates skipped). Company associations and group memberships are applied via tag operations after the contact base is loaded.
Cutover, validation, and automation rebuild inventory
We freeze Jarvis writes during cutover and run a final delta import of any contacts modified during the migration window. We validate the Mailchimp audience against the source contact count and spot-check 25-50 records for field accuracy. We deliver the written inventory of Mailchimp-compatible automations (Customer Journeys that can be rebuilt) and the CSV archives of excluded data (Opportunities, Projects, Vendors, Time Entries) to the customer's admin team. We do not rebuild Mailchimp Customer Journeys as part of the migration scope; that is a separate engagement for the customer's marketing team.
