Overview
FieldEdge and Mailchimp serve fundamentally different operational roles — FieldEdge is a field service management platform for HVAC, plumbing, and electrical contractors, while Mailchimp is an email marketing platform for audience management and campaign automation. The migration is therefore a data-consolidation project: customers and contacts from FieldEdge map into Mailchimp subscribers and merge fields, while work orders, invoices, and equipment records have no native Mailchimp equivalent and must be transformed into merge fields or exported as reference data. FlitStack AI extracts FieldEdge customer, contact, work order, invoice, and service agreement data — either via the Azure API Management API or CSV exports — and loads it into Mailchimp using Mailchimp's batch subscriber API. Field service metadata like work order status, technician name, service agreement expiry, and equipment type becomes merge fields on the Mailchimp subscriber record. Tags from FieldEdge carry over as Mailchimp tags for segmentation. The 255-character limit on Mailchimp merge fields is a hard constraint we surface during planning. Workflows and automations in FieldEdge relate to field service dispatch and invoicing and have no Mailchimp equivalent — those must be rebuilt manually in Mailchimp or remain in FieldEdge as the system of record for operations.

Object mapping
Each row shows how a FieldEdge 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.
FieldEdge
Customer
Mailchimp
Mailchimp Audience / Subscriber
1:1FieldEdge customers map directly to Mailchimp subscribers. Company name becomes the subscriber name, address maps to Mailchimp's address merge fields, and primary phone and email map to standard Mailchimp subscriber fields. A Mailchimp audience is created for each FieldEdge company record.
FieldEdge
Contact
Mailchimp
Mailchimp Subscriber
1:1FieldEdge contacts map to Mailchimp subscribers using the contact's email as the unique identifier. First name, last name, phone, and email map to Mailchimp's standard FNAME, LNAME, PHONE, and EMAIL fields. Multiple contacts with unique emails within one FieldEdge customer create multiple Mailchimp subscribers.
FieldEdge
Contact (multi-contact households / businesses)
Mailchimp
Mailchimp Subscriber + Tags
many:1When one email address appears on multiple FieldEdge contact records (e.g., different roles at the same customer), we create one Mailchimp subscriber per email and apply tags for each contact role. This prevents duplicate subscriber creation while preserving the contact role context.
FieldEdge
Work Order
Mailchimp
Mailchimp Subscriber Merge Fields
1:1Mailchimp has no native work order object. Work order metadata (work order number, status, service type, technician, service date, description, total amount) maps to Mailchimp merge fields on the subscriber record. Merge field names follow Mailchimp's MERGEn convention. Long text fields (descriptions, notes) are truncated at 255 characters with a flag in the migration report.
FieldEdge
Work Order Line Item
Mailchimp
Mailchimp Subscriber Merge Fields (aggregated)
1:1Work order line items are aggregated into a single merge field capturing part numbers, descriptions, and quantities. Full line-item detail exceeds Mailchimp's merge field capacity and must remain as reference data in FieldEdge. The aggregated summary provides context for email personalization without losing the data entirely.
FieldEdge
Invoice
Mailchimp
Mailchimp Subscriber Merge Fields
1:1Invoice metadata (invoice number, status, date, amount, balance due) maps to merge fields on the Mailchimp subscriber. Full invoice history and line-item detail have no Mailchimp equivalent and must remain in FieldEdge. Storing the most recent invoice status provides a signal for re-engagement campaigns.
FieldEdge
Service Agreement
Mailchimp
Mailchimp Subscriber Merge Fields + Tags
1:1Service agreement type, status, start date, and end date map to Mailchimp merge fields. Agreement status drives Mailchimp subscriber tags: 'Active Service Agreement', 'Expired Service Agreement', or 'No Service Agreement'. Monthly recurring revenue (MRR) is stored as a merge field for segmentation into high-value and standard service tiers.
FieldEdge
Equipment / Asset
Mailchimp
Mailchimp Subscriber Merge Fields
1:1Equipment records (manufacturer, model, serial number, install date, warranty status) attached to a FieldEdge customer map to merge fields on the corresponding Mailchimp subscriber. Mailchimp has no native equipment object, so this metadata is preserved as custom merge fields for segmentation by equipment type or warranty status.
FieldEdge
Custom Properties (Customer / Contact)
Mailchimp
Mailchimp Merge Fields
1:1FieldEdge custom properties on Customer and Contact records map 1:1 to Mailchimp merge fields. Text, number, date, and pick-list property types map to equivalent Mailchimp merge field types. Each custom property in FieldEdge creates a corresponding merge field in the Mailchimp audience before import.
FieldEdge
Tags / Labels
Mailchimp
Mailchimp Tags
1:1Tags and labels applied to FieldEdge contacts carry over directly as Mailchimp subscriber tags. The Mailchimp tag model is fully compatible with FieldEdge's labeling system, preserving the meaning and context of each tag. Tags serve as the primary driver for segmentation in Mailchimp campaigns, including roles like 'Decision Maker', 'Billing Contact', 'Site Manager', and equipment-specific tags such as 'Equipment Type: HVAC' or 'Equipment Type: Plumbing'. Subscriber tags enable targeted messaging to specific audience segments without requiring additional data manipulation after migration.
FieldEdge
Field Service Workflows / Dispatch Rules
Mailchimp
No Equivalent
1:1FieldEdge's dispatch automation, work order routing, and technician assignment rules are field service constructs with no Mailchimp equivalent. These must remain in FieldEdge as the system of record for field operations. Any email triggers tied to these workflows must be rebuilt in Mailchimp using Mailchimp Automations.
FieldEdge
Native Mailchimp Integration (FieldEdge Premier)
Mailchimp
Manual Export / API Sync
1:1FieldEdge's Premier tier includes a native Mailchimp integration that syncs customer lists. This integration does not transfer to the destination Mailchimp account and must be rebuilt manually after migration. FlitStack documents the current sync rules before migration so your team can recreate them in Mailchimp.

Migration approach
Extract FieldEdge data via API or CSV
We begin by determining the most reliable extraction path from FieldEdge — either the Azure API Management API (available to integrated partners) or CSV exports from the FieldEdge UI for customers, contacts, work orders, invoices, and service agreements. If the API is available, we apply throttling logic to avoid overwhelming the endpoint and batch records to manage volume. If CSV exports are required, we parse and consolidate multiple export files. The extraction method is documented before mapping begins so downstream validation has a known data boundary.
Plan merge field mapping and validate data quality
We review FieldEdge's data schema — custom properties, work order fields, service agreement metadata — and map each to a Mailchimp merge field or tag. During this phase, we identify contacts without email addresses (which cannot be imported into Mailchimp), duplicate email addresses across multiple contacts, and fields that will truncate at Mailchimp's 255-character merge field limit. The mapping plan is reviewed with your team before any data movement begins. Contacts missing required fields are flagged in a pre-migration data quality report.
Set up Mailchimp audience and merge fields
Before importing data, we create the Mailchimp audience and pre-configure all merge fields referenced in the mapping plan. Standard merge fields (FNAME, LNAME, PHONE, EMAIL, ADDRESS) are created using Mailchimp's defaults. Custom merge fields for work order status, technician name, service agreement expiry, equipment type, and other field service metadata are created using Mailchimp's MERGEn naming convention. Tags for contact roles and customer status are pre-configured in Mailchimp so they are available for immediate assignment during import.
Import contacts in batches and apply tags
Cleaned and validated contacts are imported into Mailchimp in batches using Mailchimp's batch subscriber API. We verify the imported subscriber count matches the expected record count and flag any contacts that failed import due to malformed email addresses or API errors. Tags for contact roles (Decision Maker, Billing Contact) and customer status (Active Service Agreement, No Service Agreement) are applied during or immediately after import. Deduplication logic handles contacts with matching email addresses by role — each unique email creates one subscriber, with multiple roles captured as tags.
Map work order and service agreement metadata to merge fields
Field service metadata from work orders, service agreements, and equipment records is mapped to pre-configured Mailchimp merge fields on the corresponding subscriber record. Work order status, technician name, service date, and total amount are stored as merge fields to support segmentation for follow-up campaigns and technician-specific communications. For records with long text fields (job descriptions, resolution notes), we truncate at 255 characters and flag the record in the migration report so your team knows where context was reduced.
Validate import, deliver migration report, and configure delta pickup
We run a validation pass checking subscriber counts, merge field population rates, and tag assignment accuracy across a representative sample of records. The final migration report documents what was migrated (customers, contacts, merge fields, tags), what was truncated (long text fields), what could not be migrated (contacts without email), and what must be rebuilt manually (Mailchimp automations and integration). A delta-pickup window captures any new or modified FieldEdge records created during the cutover window before your team switches to Mailchimp as the active marketing platform.
