Overview
ServiceTracker organizes field-service operations around clients, contacts, work orders, projects, assets, and invoices. Mailchimp organizes everything around subscribers in audiences, using merge fields and tags to store profile data. The only overlapping data is contact information: names, emails, phone numbers, company affiliations, and custom fields can map into Mailchimp subscriber profiles. ServiceTracker's work orders, service history, invoicing, dispatch rules, scheduling, and location data have no Mailchimp schema equivalent and cannot migrate. We read from ServiceTracker API using CSV or JSON export, map every contact field to Mailchimp's standard and custom fields, create merge tags dynamically, and load contacts in batched API calls that respect Mailchimp's throttling limits. Original ServiceTracker record IDs are stored on each Mailchimp contact as a reference field for audit and delta-run de-duplication. Workflows, automation rules, and dispatch logic in ServiceTracker are field-service-specific and must be rebuilt manually as Mailchimp automations if needed — we provide an exported definition for reference.
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 ServiceTracker 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.
ServiceTracker
Client
Mailchimp
Audience / Subscriber
1:1ServiceTracker Client records hold the business entity — company name, billing address, primary contact, and custom fields. We extract these as contact profiles in a Mailchimp Audience. The client name becomes the subscriber's company affiliation stored in a merge field; the primary contact name and email become the subscriber's core record.
ServiceTracker
Contact
Mailchimp
Subscriber
1:1ServiceTracker Contact records map 1:1 to Mailchimp subscribers — first name, last name, email, phone, address. These are Mailchimp's standard subscriber fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS). Each Contact from ServiceTracker becomes one subscriber in the target Mailchimp audience. Each mapped field is validated against Mailchimp's schema to ensure compatibility.
ServiceTracker
Custom Client Fields
Mailchimp
Merge Tags
1:1ServiceTracker custom fields on Client records (dropdown menus, text fields, date fields) require manual creation as Merge Tags in the Mailchimp Audience before migration. We provide a field-mapping manifest listing every custom field name, type, and pick-list value so your Mailchimp admin creates the correct tag type (text, number, dropdown, date, or checkbox) in advance.
ServiceTracker
Custom Contact Fields
Mailchimp
Merge Tags
1:1ServiceTracker custom fields on Contact records map to Mailchimp merge tags the same way. Pick-list values in ServiceTracker become Mailchimp merge tag options. We flag any field types (like multi-select or rich text) that cannot map directly to a Mailchimp merge tag type and recommend alternatives such as tag-based segmentation.
ServiceTracker
Customer Type / Category
Mailchimp
Tag / Segment
1:1ServiceTracker uses customer-type or category pick-lists to classify clients (e.g., Residential, Commercial, Industrial). These values map to Mailchimp Tags applied at import time so you can build segments in Mailchimp without needing a matching merge tag. Each ServiceTracker category value is applied as a tag on the subscriber record.
ServiceTracker
Service Address
Mailchimp
Merge Tag / Address Field
1:1ServiceTracker stores separate service-location address fields per client or work order. Mailchimp's standard address merge field uses a combined street/city/state/zip structure. We split ServiceTracker's service address fields into Mailchimp's address merge fields. If multiple service locations exist per client, additional locations are stored in a custom merge tag as a comma-separated reference.
ServiceTracker
Work Order
Mailchimp
No Equivalent
1:1Work orders are the core operational record in ServiceTracker — job type, status, assigned technician, parts used, service notes, and timestamps. Mailchimp has no work-order or job-record schema. Work orders cannot migrate to Mailchimp; they remain in ServiceTracker or get exported as a CSV and archived separately.
ServiceTracker
Project / Contract
Mailchimp
No Equivalent
1:1ServiceTracker projects and service contracts associate multiple work orders, milestones, and billing terms. Mailchimp organizes contacts into audiences and segments but has no project or contract object. These records have no Mailchimp equivalent and stay behind or are exported as reference CSVs.
ServiceTracker
Invoice / Payment
Mailchimp
No Equivalent
1:1ServiceTracker generates invoices and tracks payment status linked to work orders and clients. Mailchimp is an email platform with no billing or payment schema. Invoices cannot migrate and must remain in ServiceTracker or be moved to a dedicated accounting tool.
ServiceTracker
Asset / Equipment Record
Mailchimp
No Equivalent
1:1ServiceTracker asset records track equipment, serial numbers, maintenance schedules, and service history linked to client sites. Mailchimp has no asset or equipment schema. Asset records cannot migrate and remain in ServiceTracker or are exported as a standalone CSV. This preserves historical context even if the records cannot be used within Mailchimp.
ServiceTracker
Notes / Attachments on Contact
Mailchimp
Note (external reference)
1:1ServiceTracker may store internal notes or file attachments on contact records. Mailchimp does not have a native note or attachment feature for subscriber profiles. Notes text is preserved in a merge tag as a read-only reference; attachments cannot migrate. Please review the exported notes for completeness.

Migration approach
Audit ServiceTracker contact and client records
We connect to the ServiceTracker API or export via CSV, pulling all Client and Contact table records — including custom fields, customer-type pick-list values, service-address fields, and create timestamps. We count records, identify missing email addresses, and catalog every custom field name and type. This produces the field-mapping manifest used in all subsequent steps and surfaces any data-quality issues before migration begins.
Create Mailchimp merge tags and set up the audience
Based on the field-mapping manifest, we provide a detailed setup checklist for your Mailchimp admin: which merge tags to create, what type (text, number, date, dropdown, checkbox), and which pick-list values to enter for dropdowns. We also recommend enabling double opt-in before contacts are loaded. This step prevents import errors caused by missing merge tag types mid-migration and ensures your audience structure aligns with the source data schema.
Run a sample migration with 50–100 contacts
A representative slice of ServiceTracker contacts — spanning different customer types, geographic regions, and custom field values — migrates to Mailchimp first. We generate a field-level comparison showing source values versus Mailchimp subscriber profile values. You verify that names, emails, merge tag values, and applied tags are correct before we commit to the full run. Any field mapping errors are corrected before the bulk migration.
Execute bulk migration in batched API calls
Full migration runs against the Mailchimp API. Contacts are loaded in batches of up to 500, with each batch completing before the next starts — keeping concurrent connections below Mailchimp's 10-connection limit. Merge tags are applied per contact. Customer-type pick-list values are applied as Mailchimp tags at import. Source system IDs and original create dates are stored as custom merge fields. A delta-pickup window (24 hours) captures any new or modified ServiceTracker contacts during the migration window.
Validate counts, spot-check fields, and deliver archive package
Post-migration, we compare the total subscriber count in Mailchimp against the imported contact count from ServiceTracker, flagging any records that failed to load. We spot-check 20–30 subscriber profiles to verify field-level accuracy across standard fields, merge tags, and applied tags. We deliver the full archive package: Mailchimp subscriber export, ServiceTracker reference CSV of unmigrated records (work orders, invoices, contacts without email), and workflow export JSON for any ServiceTracker automations you want to reference when rebuilding Mailchimp automations.
