Overview
Field Service Trakker stores customer relationships alongside work orders, scheduling, dispatch logs, and site locations. Mailchimp models everything as an Audience of contacts with Merge Tags and standard address fields. The migration carries customer contact data — names, emails, phone numbers, addresses, service types, and custom properties — into Mailchimp's audience structure using Mailchimp's REST API and bulk-import endpoint. Work orders, scheduling data, technician assignments, and dispatch logs have no native Mailchimp equivalent; those records either become custom fields on the contact or require a different data storage approach. Email engagement history (opens, clicks) captured inside Field Service Trakker is platform-specific and does not transfer — Mailchimp begins tracking engagement from the moment your first campaign sends. FlitStack sequences the export, field-type transformation, value mapping for status pick-lists, and bulk upload so contacts land in the correct audience with tags applied before your go-live date. During the migration, we handle duplicate detection, invalid email flagging, and suppression list population to maintain list hygiene from day one.

Object mapping
Each row shows how a Field Service Trakker 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.
Field Service Trakker
Customer / Client
Mailchimp
Audience Contact
1:1Field Service Trakker customer records map to Mailchimp audience contacts. Each customer becomes one contact with standard fields (name, email, phone) and address data populating Mailchimp's built-in address merge fields. Duplicate contacts with identical emails merge automatically in Mailchimp during import, preventing duplicate records from accumulating in your audience over time.
Field Service Trakker
Customer Custom Fields
Mailchimp
Merge Tag
1:1Custom fields on Field Service Trakker customers (account type, billing tier, customer since date, technician assigned) require Merge Tag creation in Mailchimp before migration. We map each custom field's data type to the appropriate Mailchimp field type: text, number, date, or pick-list. The field type mapping ensures data validation rules work correctly in Mailchimp after import.
Field Service Trakker
Service Type / Customer Type
Mailchimp
Audience Tag
1:1Field Service Trakker customer-type labels (residential, commercial, preventive maintenance) map directly to Mailchimp Tags. Tags apply to contacts during migration for instant segmentation — no post-migration tagging required. Each unique type value becomes one tag in Mailchimp, and contacts can have multiple tags applied simultaneously for compound segmentation.
Field Service Trakker
Site / Location Address
Mailchimp
Contact Address Fields
1:1Field Service Trakker stores full address strings on Site records. We parse and split these into Mailchimp's structured address fields: addr1, addr2, city, state, zip, country. Malformed or incomplete addresses map to addr1 as free text with a flag for manual review, ensuring no address data is lost during the transformation process.
Field Service Trakker
Site / Location Name
Mailchimp
Merge Tag
1:1When customers have multiple service sites in Field Service Trakker, the primary site name maps to a Merge Tag (SITE_NAME) on the contact. Secondary site names require multiple contact records or a custom field storing a comma-separated list — flagged for your Mailchimp admin to decide based on your segmentation needs.
Field Service Trakker
Work Order Status
Mailchimp
Custom Field
1:1Work order status values (scheduled, in-progress, completed, cancelled) have no native Mailchimp equivalent. We preserve the most recent work order status as a Merge Tag (LAST_STATUS) for reference — but Mailchimp cannot natively trigger automations from work order state changes since the platform lacks a work order object model.
Field Service Trakker
Work Order Count
Mailchimp
Merge Tag
1:1The total count of work orders per customer in Field Service Trakker migrates as a number-type Merge Tag (TOTAL_JOBS). This gives your marketing team a quantitative signal for high-value customer campaigns without needing to query the source system after migration is complete.
Field Service Trakker
Technician Assignment
Mailchimp
Merge Tag
1:1Technician names assigned to customer accounts in Field Service Trakker map to a Merge Tag (PRIMARY_TECH). Mailchimp cannot route campaigns or automations based on technician assignment — this field is informational for your marketing team to use in segmentation logic or personalization tokens.
Field Service Trakker
Invoice History
Mailchimp
Custom Field
1:1Billing and payment history from Field Service Trakker has no native equivalent in Mailchimp. If retention of this data is required, we store the most recent invoice date and total as Merge Tags (LAST_INVOICE_DATE, LAST_INVOICE_AMOUNT) — full invoice history requires a separate system designed for financial record storage.
Field Service Trakker
Opt-out / Subscription Status
Mailchimp
Audience Suppression List
1:1Active customers in Field Service Trakker migrate as subscribed Mailchimp contacts. Customers marked as do-not-contact, unsubscribed, or with invalid email addresses are exported separately and uploaded to Mailchimp's suppression list to protect deliverability before the migration completes.
Field Service Trakker
Customer Create Date
Mailchimp
Merge Tag
1:1The original customer creation date from Field Service Trakker cannot replace Mailchimp's native CreatedAt timestamp (set at import time). We preserve it as a date-type Merge Tag (ORIGINAL_CREATE_DATE) for date-based segmentation and lifecycle reporting across the full customer history.
Field Service Trakker
Contact Role (Primary / Billing)
Mailchimp
Merge Tag
1:1When a single customer account in Field Service Trakker has multiple contact roles (primary contact, billing contact, site manager), we map the primary role directly and store secondary roles as a text Merge Tag (CONTACT_ROLES) — comma-separated for segmentation reference and reporting purposes.

Migration approach
Audit Field Service Trakker data and design Merge Tag schema
FlitStack AI exports a full inventory of Field Service Trakker customer records, Site records, custom field definitions, and pick-list values. We analyze which records qualify for Mailchimp migration and which Field Service Trakker data has no Mailchimp equivalent. The output is a Merge Tag schema — a list of every Merge Tag to create in Mailchimp, its data type, and which Field Service Trakker field feeds it. We deliver this as a pre-migration checklist so your Mailchimp admin creates the fields before the import runs.
Export and transform customer contact data
We export customer records and Site records from Field Service Trakker via the platform's API or CSV export. Address strings are parsed and split into Mailchimp's structured address fields (addr1, city, state, zip, country). Pick-list values for customer status and service tier are mapped to Mailchimp Merge Tag pick-list values. Custom fields are typed (text, number, date) according to their Field Service Trakker data type. Records are prepared in batches of 5,000 for Mailchimp's bulk import endpoint.
Map service types to Mailchimp Tags
Field Service Trakker customer-type labels are extracted and applied as Mailchimp Tags during migration. Each unique value in the customer type or service category field becomes one tag in Mailchimp — for example, 'residential', 'commercial', 'preventive-maintenance'. Tags apply to contacts at import time so segmentation is immediately available when your first campaign launches. We map every unique type value found in the export and flag any values that may require additional tags.
Import a sample audience for validation
Before committing the full migration, we upload a representative sample of 50–100 contacts to your Mailchimp audience. We verify that Merge Tags populate correctly, address fields parse as expected, Tags apply to the right contacts, and email addresses pass Mailchimp's validation. A field-level diff report is generated comparing source Field Service Trakker values against the imported Mailchimp contact data. You review and approve before the full run proceeds.
Run full migration and sync suppression list
The complete customer contact dataset imports to Mailchimp using Mailchimp's bulk-import API. A delta-pickup window captures any new records or status changes in Field Service Trakker during the import window. Separately, contacts marked as unsubscribed, do-not-contact, or with invalid email addresses are compiled and uploaded to Mailchimp's suppression list to protect deliverability before your first campaign sends. An audit log records every record imported, any field-level warnings, and the suppression list upload.
