Overview
Formitize organizes business data around contacts, clients, jobs, and custom forms — it is a field-service and operations CRM. Mailchimp organizes data around audiences, members, tags, and merge fields — it is a permission-based email marketing platform. These models overlap only at the contact level, so the migration centers on extracting Formitize contacts with their associated custom field values and loading them into Mailchimp as audience members. FlitStack AI reads Formitize contact records via API, builds a Mailchimp merge field schema matching every source custom field, and performs a bulk import with field-level validation before your team goes live. Workflows, job records, quotes, and documents from Formitize have no email-marketing equivalent in Mailchimp — those are surfaced in the migration plan as rebuild items. The delta-pickup window captures any new Formitize contacts added during the cutover window so your Mailchimp audience reflects the final state at switchover. All existing Formitize contact timestamps and original field values transfer without modification, ensuring historical accuracy for your marketing records.
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 Formitize 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.
Formitize
Contact
Mailchimp
Audience Member
1:1Formitize contacts map 1:1 to Mailchimp audience members. The contact's email address serves as the primary key for the migration — FlitStack resolves each Formitize email to a corresponding Mailchimp member record, creating new members where no match exists or updating existing ones by email match during the import process.
Formitize
Client
Mailchimp
Audience + Tag
1:1Formitize clients represent businesses associated with contacts. Since Mailchimp has no native client-account object, FlitStack maps each unique client name to a Mailchimp tag that gets applied to all contacts belonging to that client. This approach preserves the original grouping relationship from Formitize for segmentation and filtering purposes.
Formitize
Contact Custom Field (text, number, date)
Mailchimp
Merge Field
1:1Every Formitize custom contact field becomes a Mailchimp merge field of the corresponding type. Text fields become text merge fields, date fields become date merge fields, and number fields become number merge fields — all created in the Mailchimp audience before any data import begins.
Formitize
Contact Custom Field (pick-list / dropdown)
Mailchimp
Merge Field (radio or dropdown)
1:1Formitize pick-list custom fields migrate to Mailchimp merge fields with identical option values maintained. Each Formitize pick-list value is created as a merge field option in Mailchimp so that email templates can reference the values for personalization and conditional content without requiring manual re-entry of the options.
Formitize
Contact Status (active/inactive)
Mailchimp
Member Status
1:1Formitize active contacts are mapped to Mailchimp subscribed status to ensure they receive campaigns. Formitize inactive or deleted contacts are mapped to unsubscribed status in Mailchimp to prevent accidentally mailing outdated or unwanted records during the migration.
Formitize
Job (service records)
Mailchimp
No equivalent
1:1Formitize jobs, service records, and job-linked notes have no email-marketing analogue in Mailchimp's contact-centric model. These records are documented in the migration plan as reference-only exports, and your team decides whether to archive them separately or rebuild service-history summaries as Mailchimp tags for future reference.
Formitize
Form (submission data)
Mailchimp
No equivalent
1:1Formitize form submissions represent operationally specific records that do not map cleanly to Mailchimp's contact model. Form submission data is exported as a separate reference file for archival purposes. Mailchimp signup forms are set up independently after the migration using Mailchimp's native form builder tools.
Formitize
Quote / Invoice
Mailchimp
No equivalent
1:1Formitize quotes and invoices are billing documents with no email marketing counterpart in Mailchimp's feature set. These records remain out of scope for the Mailchimp migration — they stay in Formitize or can be migrated separately via a billing-system export if your team requires that data in another platform.
Formitize
Workflow
Mailchimp
Mailchimp Automation
1:1Formitize Workflows automate job routing, compliance tasks, and multi-step business processes that cannot directly translate to Mailchimp's email-trigger automation model. FlitStack exports the workflow definitions as a JSON reference file so your team can manually evaluate and map the business logic to appropriate Mailchimp customer journeys.
Formitize
Asset
Mailchimp
No equivalent
1:1Formitize assets represent physical equipment or inventory items tracked in connection with service jobs. Mailchimp's platform has no asset object or inventory tracking capability. Asset data is exported as a reference CSV file for archival purposes — it is not imported into the Mailchimp audience.

Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Formitize gotchas
Limited bulk export mechanism complicates migration scoping
Custom field schemas are per-account, not organizational templates
Workflow definitions do not transfer between platforms
Asset zone and GPS data requires explicit extraction
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

Migration approach
Audit Formitize contacts and custom field schema
FlitStack reads your Formitize account via API to enumerate all contact records, custom field definitions, and client associations. We produce a comprehensive schema inventory listing every standard field and custom field with its data type, sample values, and a flag for any field exceeding Mailchimp's 255-character merge field limit. This inventory drives the merge field creation plan and the pre-migration cleanup checklist your team reviews before proceeding.
Create Mailchimp audience and merge fields
Using the schema inventory, FlitStack creates the matching merge field structure in your Mailchimp audience before any data loads. Text, number, date, and dropdown fields are all created with the appropriate Mailchimp field types. If your Formitize setup exceeds Mailchimp Standard's 30-field limit, we surface this finding during this step and your team decides whether to upgrade to Premium or consolidate fields before the migration proceeds.
Map client relationships to Mailchimp tags
Formitize client-contact associations are not native to Mailchimp's flat audience model. FlitStack extracts the complete list of unique Formitize client names and creates corresponding tags within your Mailchimp audience. Each contact receives the tag(s) for its associated client(s) during the bulk import, preserving the original grouping relationship for future segmentation, campaign filtering based on client associations, and automated audience splits in Mailchimp automations.
Run sample import with field-level diff
A representative slice of Formitize contacts — typically 100–500 records spanning different custom field combinations — imports into Mailchimp first. FlitStack generates a field-level diff showing every mapped value as it appears in Formitize versus how it landed in Mailchimp, including truncation events for long fields and tag assignments for client grouping. You review the diff and approve before the full run commits.
Execute full import with delta-pickup window
The full contact set loads into Mailchimp with the validated schema and tag structure. A delta-pickup window of 24–48 hours captures any new Formitize contacts or updated records added during the cutover period. FlitStack's audit log records every imported member, and one-click rollback is available if the import produces unexpected results. After the delta window closes, your Mailchimp audience reflects Formitize's final contact state at go-live.
