Overview
Moving from Flexie to Mailchimp is an audience-consolidation migration rather than a schema-preservation migration. Flexie is a workforce management platform built around Workers, Shifts, Venues, and Shift Assignments; Mailchimp is an email marketing platform built around Audiences, Contacts, Tags, Segments, and Automations. The only first-class object that maps directly is Flexie Workers to Mailchimp Contacts. Shift scheduling data has no equivalent in Mailchimp and is flagged as non-migratable before migration begins. Custom properties on Worker records translate to Mailchimp merge fields, which we pre-create in the destination audience before contact import. Venue assignments become tags or segments depending on the customer's segmentation strategy. Flexie workflows are platform-native automation sequences and cannot be exported as code; we document every active workflow with its trigger, conditions, and actions so the customer's team can rebuild them in Mailchimp Customer Journeys. We do not migrate Entity Forms, Documents, or Shift records as these have no structural equivalent in Mailchimp's data model.

Object mapping
Each row shows how a Flexie 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.
Flexie
Worker
Mailchimp
Contact (within Audience)
1:1Flexie Workers map to Mailchimp Contacts within a destination Audience. First name, last name, and email address are the core fields. We resolve the email field from Flexie's worker contact details and use it as the subscriber key. Workers without a valid email address are held in a reconciliation queue for manual review before import because Mailchimp requires a valid email for contact creation.
Flexie
Custom Properties (Worker)
Mailchimp
Merge Fields
lossyEach Flexie custom property on a Worker record translates to a Mailchimp merge field in the destination Audience. We pre-create the merge field schema before contact import, mapping Flexie field types (text, number, date, picklist) to Mailchimp merge field types (text, number, date, dropdown). Picklist values from Flexie custom properties must be reviewed for character limits; Mailchimp merge field options support up to 255 characters per value.
Flexie
Venue
Mailchimp
Tag or Segment
1:manyFlexie Venues do not have a direct Mailchimp equivalent because Mailchimp is organized by Audience rather than by location. We offer two strategies: (1) Venue becomes a tag applied to every Worker assigned to that venue, preserving the worker-to-venue relationship; (2) Venue becomes a Segment definition within the Mailchimp Audience based on a merge field value. The customer chooses the strategy during scoping. Multi-location operations with over 20 venues may prefer tags for simplicity; operations requiring location-based reporting may prefer segments.
Flexie
Shift Assignment
Mailchimp
Tag
1:1Shift Assignment records link Workers to Shifts with status (accepted, pending, declined) and timestamp. If the customer wants to preserve shift participation history in Mailchimp, we apply tags like 'shift-accepted-q3-2025' or 'shift-pending' to the Worker's contact record. This is an optional scope item; Mailchimp cannot represent shift times or schedules as structured data. Tags are applied in batch after the core contact migration completes.
Flexie
Workflow
Mailchimp
Customer Journey (documented, not migrated)
lossyFlexie workflows are automation sequences with triggers, conditions, and actions that do not export as code to any external system. We document every active Flexie workflow during discovery, capturing the trigger type (entity form submission, shift status change, date-based), the conditional logic, and the sequence of actions. This document is delivered to the customer for manual rebuild in Mailchimp Customer Journeys. Workflow documentation includes a recommended Mailchimp trigger, condition, and action equivalent for each Flexie workflow.
Flexie
Entity Form
Mailchimp
Signup Form (documented, not migrated)
lossyFlexie Entity Forms serve as data entry points and workflow triggers within the workforce management context. Mailchimp Signup Forms serve a different purpose (audience capture for marketing). These do not map to each other structurally. We document the Flexie Entity Form field definitions and submission records as part of the schema discovery, but form rebuild is outside migration scope. The customer recreates signup forms in Mailchimp based on the contact fields they wish to capture.
Flexie
Document
Mailchimp
Not migratable
1:1Flexie Documents are files attached to Workers, Shifts, or Venues (such as certifications, onboarding paperwork, or shift schedules). Mailchimp has no document attachment capability on contacts. We extract document metadata (filename, URL, upload date, attached record type) and deliver it as a file inventory. Actual file hosting must be moved separately to a document management system or cloud storage, and links can be preserved as URL merge fields on the contact record if needed.
Flexie
Shift
Mailchimp
Not migratable
1:1Flexie Shifts represent time blocks with start time, end time, venue assignment, and capacity. Mailchimp has no scheduling or time-block model. Shift records cannot be represented in Mailchimp's audience structure. We extract shift metadata (shift date, venue, status) as a summary report during discovery and flag it as non-migratable. If the customer needs shift-related communications (reminders, confirmations), we document the Flexie shift trigger logic for rebuild as Mailchimp automations using date-based triggers.

Migration approach
Discovery and Flexie API access
We audit the Flexie account via API access (or with customer-assisted export if API documentation is insufficient) to extract Worker records with all standard and custom fields, Venue records, active Workflow definitions, Entity Form schemas, and document metadata. We also identify the Flexie contract renewal date to plan the cutover window and minimize exit fee exposure if the customer is on an annual plan. The discovery output is a written Flexie data inventory and a Mailchimp audience configuration plan.
Mailchimp audience setup and merge field pre-creation
We create the destination Mailchimp Audience and pre-create merge fields matching the Flexie custom property schema. Picklist values from Flexie are mapped to Mailchimp merge field options with character truncation applied where values exceed 255 characters. If the customer chooses a tag-based venue strategy, we create the initial tag group in Mailchimp. If the customer chooses segments, we define the segment filter logic for each venue. Merge field creation is validated before contact import begins.
Contact extraction and email reconciliation
We extract Worker records from Flexie with all mapped fields and run an email validation pass. Workers without a valid email address are isolated in a reconciliation queue. Workers with duplicate email addresses are flagged for the customer to resolve (Mailchimp uses email as the subscriber key, so duplicates cause import failures). Workers with invalid email formats are held for manual review. We provide the customer with a deduplication report and guidance on resolving the queue before migration resumes.
Contact import and venue tagging
We import validated Worker contacts into the Mailchimp Audience using the Mailchimp API with batch chunking and exponential backoff on rate limit responses (2,000 requests per minute on Standard plan). After core contact import completes, we apply venue tags in batch to every Worker contact based on the Flexie Venue-to-Tag mapping defined during scoping. Tags are applied via the Mailchimp Tags API endpoint with member batch operations for efficiency. Each batch emits a reconciliation count for verification.
Shift metadata export and automation inventory delivery
We export Flexie shift metadata (shift dates, venues, statuses) as a CSV report and deliver it alongside the migration completion report. We deliver the Flexie Workflow inventory document with every active workflow's trigger, conditions, and actions mapped to a recommended Mailchimp Customer Journey equivalent. Document metadata (filename, URL, attached record type) is delivered as a separate file inventory. These deliverables are the customer's handoff package for manual rebuild in Mailchimp.
Cutover and post-migration validation
We freeze Flexie write access during the cutover window to prevent record drift. We run a final delta import for any Worker records modified after the initial extraction. We validate the Mailchimp audience contact count against the Flexie Worker count and spot-check 20-30 records for field-level accuracy. We deliver the migration completion report with record counts, tag counts, and a list of any unreconciled records. We do not rebuild Flexie workflows as Mailchimp Customer Journeys inside the migration scope; the automation inventory is a handoff document for the customer's team to rebuild post-migration.
