Overview
Mobile Worker is a field-service and mobile-workforce management platform — it tracks workers, jobs, assignments, time entries, and customer locations. Mailchimp is an email marketing platform organized around audiences, contacts, tags, and merge fields. These two data models are structurally different: Mobile Worker stores operational records (work orders, assignments, job statuses) that have no native equivalent in Mailchimp. The migration carries every contact, customer organization, and worker record into Mailchimp contacts, maps worker status and service-history data into custom merge fields and tags, and preserves work-order references as notes or custom field text for segmentation use cases. FlitStack AI sequences the migration so contacts land in Mailchimp first, then custom fields and tags are populated from the operational history. Mailchimp automations, email templates, and campaign structures do not migrate — those must be rebuilt in Mailchimp's automation builder. The migration runs against the Mailchimp API using scoped read access to Mobile Worker; your team continues working in Mobile Worker during cutover, with a delta-pickup window capturing any in-flight 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 Mobile Worker 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.
Mobile Worker
Worker
Mailchimp
Contact
1:1Mobile Worker Worker records map directly to Mailchimp Contacts. Each worker email, phone, and name field transfers as a Mailchimp contact profile field. Workers without email addresses are flagged for manual review before migration. The mapping also captures the worker's original hire date and team assignment as separate fields, preserving tenure and organizational context for segmentation and reporting purposes.
Mobile Worker
Worker Status
Mailchimp
Tag / Merge Field
1:1Mobile Worker worker status values (Active, On Job, On Break, Offline, Inactive) have no Mailchimp native equivalent. FlitStack creates a STATUS__c merge field on the Mailchimp audience and maps each status value by name. Tags (e.g., 'On-Job', 'Active-Worker') can also be applied for segmentation.
Mobile Worker
Customer (Organization)
Mailchimp
Contact (merge field ORGANIZATION)
1:1Mobile Worker Customer records carry company name, site address, and primary contact name. The company name maps to a custom FNAME merge field or a separate ORGANIZATION merge field. Primary contact from the Customer record can merge into the Worker's contact profile if the worker is also a subscriber.
Mobile Worker
Work Order
Mailchimp
Contact Notes / Custom Text Field
1:1Work orders carry job name, status, location, schedule, and assignment data. Mailchimp has no work-order object. FlitStack summarizes each worker's last N work orders into a JOB_HISTORY__c text field (JSON or plain text) and appends a job-history note to the contact record for reference.
Mobile Worker
Assignment
Mailchimp
Tag / Merge Field
1:1Mobile Worker Assignments link a Worker to a Work Order with a role and status. Assignment roles (e.g., Primary Technician, Helper) become Mailchimp Tags applied to the contact record so campaigns can segment by field-role without a custom object. Status values from assignments also transfer as separate tags, enabling targeting based on whether a worker is currently assigned or available.
Mobile Worker
Time Entry
Mailchimp
Custom Merge Field
1:1Time entries track hours worked per job. Mailchimp has no time-tracking model. FlitStack preserves the most recent time entry date and total hours as TOTAL_HOURS__c and LAST_JOB_DATE__c merge fields — useful for re-engagement campaigns but not for operational reporting. Multiple time entries per worker accumulate into the total hours field, while the most recent entry date reflects the worker's latest activity window.
Mobile Worker
Location / Site Address
Mailchimp
Contact Address Fields
1:1Mobile Worker site addresses attached to Customers map to Mailchimp's built-in address merge fields (ADDR1, CITY, STATE, ZIP, COUNTRY). Multiple site addresses per customer collapse to the primary address on the contact profile; secondary sites preserved as a custom LOCATIONS__c text field.
Mobile Worker
Worker Photo / Document
Mailchimp
External URL in Merge Field
1:1Worker profile photos and certifications stored in Mobile Worker cannot live inside Mailchimp. FlitStack downloads each file and populates a PROFILE_URL__c merge field pointing to the re-hosted file URL. Mailchimp does not host these natively — they must live in external storage (S3, Dropbox, etc.).
Mobile Worker
Custom Object (Worker Extension)
Mailchimp
Custom Merge Field
1:1Mobile Worker custom objects extending Worker (e.g., certifications, equipment assignments) map to Mailchimp custom merge fields. Field types map to merge field types where supported (text, number, date, phone). Long-text custom objects become text fields with content preserved. Array or list-type custom properties serialize into comma-separated or JSON-formatted text values stored in the corresponding merge field for reference.
Mobile Worker
Job Status Picklist
Mailchimp
Tag / Status__c Merge Field
1:1Mobile Worker job status values (Scheduled, In Progress, Completed, Cancelled) need explicit value-by-value mapping to Mailchimp tags or a STATUS__c merge field. Status color codes or priority levels do not transfer — only the named value is preserved in Mailchimp.
Mobile Worker
Mobile Worker Groups / Teams
Mailchimp
Mailchimp Tag
1:1Mobile Worker team or group assignments map directly to Mailchimp Tags applied to each contact. A worker in 'Team Alpha' receives the tag 'Team-Alpha' in Mailchimp. Tags allow segmentation by team for team-targeted campaign sends. Multiple team memberships per worker result in multiple tags, enabling complex team-based audience splits for region-specific or department-focused campaigns.
Mobile Worker
Subscription / Marketing Opt-In
Mailchimp
Mailchimp Contact Status
1:1Mobile Worker may track whether a contact has consented to marketing. This maps to Mailchimp's SUBSCRIBED / UNSUBSCRIBED / ARCHIVED contact status. FlitStack sets status per source value and surfaces any contacts with no opt-in flag for your team to decide before migration.

Migration approach
Audit Mobile Worker data and define Mailchimp audience schema
FlitStack connects via scoped read access to Mobile Worker and inventories every Worker, Customer, Work Order, Assignment, and Time Entry record. We flag records without email addresses, records missing opt-in flags, and records with file attachments. You then confirm the Mailchimp audience setup: which custom merge fields to create, what tag taxonomy to use for team and role segmentation, and which job-history fields to include. This phase produces a data audit report and a Mailchimp schema setup plan before a single record moves.
Create Mailchimp custom merge fields and tag taxonomy
FlitStack delivers a Mailchimp merge-field setup guide (or creates the fields directly via the Mailchimp API if you grant access). STATUS__c, JOB_HISTORY__c, ORGANIZATION__c, TOTAL_HOURS__c, HIRE_DATE__c, SOURCE_ID__c, and all other custom fields are created as text, date, or number merge fields on the target audience. Tag groups for TEAM, ROLE, ASSIGNMENT_ROLE, and JOB_STATUS are configured. No data moves until the schema is confirmed to be in place.
Resolve email matches and flag non-marketing contacts
Every Mobile Worker record is checked for a valid email address. Records without email are exported to a separate workfile for your team to handle manually. Records with an email are matched against existing Mailchimp contacts to detect duplicates. Opt-in status from Mobile Worker is mapped to Mailchimp contact status (Subscribed / Unsubscribed / Archived) at this stage — contacts with no marketing flag are defaulted to Archived or held for your review based on your pre-migration decision.
Run a sample migration with field-level diff
A representative slice of 100–500 records migrates first — spanning workers across different teams, job statuses, and attachment types. FlitStack generates a field-level diff report showing every merge field value as it appears in Mobile Worker versus what landed in Mailchimp. You verify job-history serialization, tag application, address mapping, and status flags before the full run commits. This is the checkpoint to correct merge field names, adjust tag taxonomy, or trim the job-history JSON before scale.
Execute full migration with delta-pickup window
The full dataset loads into Mailchimp via the Mailchimp API, respecting Mailchimp's rate limits (typically 2,000 requests per minute for Standard plans). A delta-pickup window of 24–48 hours runs concurrently: any Mobile Worker records created or modified during the migration window are captured and applied to Mailchimp so the final audience reflects Mobile Worker's state at go-live. FlitStack produces an audit log of every operation, and one-click rollback is available if contact records are misaligned or duplicate suppression fails.
