Overview
Migrating Fieldy to Mailchimp addresses a fundamental platform-type shift: Fieldy is a field-service management system built around jobs, technicians, and service dispatch, while Mailchimp is an audience-centric email marketing platform built around subscriber lists, tags, and campaign automations. FlitStack AI maps the subset of Fieldy that overlaps with Mailchimp — contact records, company data, and custom fields — into Mailchimp audiences via API. Fieldy's job records, invoice objects, service agreements, and scheduling data have no native Mailchimp counterpart and cannot migrate automatically; we document every non-transferable object with the field names and values your team needs to recreate them manually in Mailchimp automations or a separate job-management tool. The migration reads Fieldy contacts via your API credentials with scoped read-only access, transforms field names to Mailchimp merge-tag conventions, and upserts into your target Mailchimp audience. A 24–48 hour delta-pickup window captures any contacts modified in Fieldy during the cutover. Workflows, sequences, and automation logic built inside Fieldy do not transfer — those must be rebuilt in Mailchimp's automation builder after go-live.
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 Fieldy 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.
Fieldy
Customer (Fieldy CRM)
Mailchimp
Subscriber (Mailchimp Audience Member)
1:1Fieldy Customer records — which store contact name, email address, phone, and company association — map directly to Mailchimp subscribers. Each Fieldy customer with an email address becomes one subscriber record in your target Mailchimp audience. Customers without email addresses are flagged for manual review before migration.
Fieldy
Contact (standalone Fieldy CRM contact)
Mailchimp
Subscriber (Mailchimp Audience Member)
1:1Fieldy standalone Contact records map 1:1 to Mailchimp subscribers. The contact's first name, last name, and email address populate the corresponding Mailchimp merge fields. Phone number maps to the phone merge field if configured in the Mailchimp audience schema. Any additional contact details such as job title or secondary email are preserved in custom merge fields or exported as supplementary data.
Fieldy
Company (Fieldy CRM)
Mailchimp
Merge Fields on Subscriber / Audience Group
1:1Fieldy Company records store business name, industry, website, and employee count. These values migrate as Mailchimp merge fields on the Subscriber record — typically COMPANY_NAME, INDUSTRY, and WEBSITE — rather than as a separate object, since Mailchimp has no native company/account object at the subscriber level.
Fieldy
Job (Fieldy FSM)
Mailchimp
No equivalent in Mailchimp
1:1Fieldy Job records contain job type, status, scheduled date, technician assigned, service address, and completion notes. Mailchimp has no job or work-order object. These records cannot auto-migrate. FlitStack documents all Fieldy job field names and values in a CSV rebuild reference so your team can manually recreate job-status email triggers in Mailchimp automations if desired.
Fieldy
Invoice (Fieldy FSM)
Mailchimp
No equivalent in Mailchimp
1:1Fieldy Invoice records include invoice number, amount, status (paid/unpaid/overdue), line items, and payment date. Mailchimp has no invoice object. Invoice data cannot migrate to Mailchimp's subscriber schema. We export the invoice dataset separately as a CSV and flag it for import into a dedicated billing or accounting tool.
Fieldy
Quote (Fieldy FSM)
Mailchimp
No equivalent in Mailchimp
1:1Fieldy Quote records store quoted service name, line items, pricing, validity date, and acceptance status. Mailchimp has no quote object. Quotes are exported as a separate CSV with field names preserved. Your team can map quote acceptance status as a trigger for a Mailchimp automation that sends a follow-up campaign, but the quote record itself must be recreated in your quoting tool.
Fieldy
Custom Field on Customer (Fieldy FSM)
Mailchimp
Merge Field or Audience Group (Mailchimp)
1:1Fieldy custom fields on Customer records — such as service_agreement_type, preferred_technician, or renewal_date — are type-mapped to Mailchimp equivalents. Text custom fields become Mailchimp text merge tags. Date fields become Mailchimp date merge tags. Pick-list or dropdown fields in Fieldy map to Mailchimp Groups with the pick-list values as group names. Custom fields on Job or Invoice objects cannot migrate.
Fieldy
Technician / User (Fieldy FSM)
Mailchimp
Admin or User role (Mailchimp)
1:1Fieldy Users and Technicians are operational staff with dispatch assignments and service territories. Mailchimp Admin and User roles manage audience access and campaign permissions — they are not a counterpart to technician records. Technician contact information that serves as a customer-facing point of contact can be stored as a custom merge field on the subscriber if needed.
Fieldy
Location / Branch (Fieldy Multi-location)
Mailchimp
Separate Audience per location (Mailchimp)
1:manyFieldy supports multiple business locations or branches, each with its own customer and job records. When your migration involves multiple Fieldy locations, we split the contacts by location_id and upsert them into separate Mailchimp audiences — one audience per location. This preserves segmentation by branch and allows location-specific campaign targeting in Mailchimp.
Fieldy
Attachment / Photo on Job (Fieldy FSM)
Mailchimp
No equivalent in Mailchimp
1:1Fieldy job records may include photos, signed forms, or PDF attachments (e.g., service completion photos, before/after images). Mailchimp subscriber records do not support attachments or file uploads. Attachments are exported separately and can be linked in Mailchimp campaigns via URL if hosted externally, but the attachment files themselves do not migrate into Mailchimp.

Fieldy gotchas
No documented public API or bulk export endpoint
Custom workflow automations do not export as portable rules
Pricing tiers and per-user limits not publicly confirmed
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Audit Fieldy data exportability and schema
FlitStack connects to Fieldy via your API credentials with read-only access and inventories all object types available for export: Customer records, standalone Contacts, Companies, Job records, Invoices, Quotes, custom fields, and tags. We generate a schema inventory report listing every field name, data type, and non-null record count. This report identifies which objects can migrate to Mailchimp and which will be exported as separate reference CSVs. You review and approve the inventory before any data moves.
Design Mailchimp audience structure and merge tag schema
Based on the Fieldy schema inventory, FlitStack creates the Mailchimp merge tag configuration for your target audience or audiences. For multi-location Fieldy setups, we design one Mailchimp audience per location. We create the necessary merge fields (COMPANY_NAME, INDUSTRY, PREF_TECH, SRC_CREATED, etc.), configure Groups for Fieldy pick-list fields, and establish tag-naming conventions. This schema is validated against Mailchimp's API before migration records are written so field types are correct on first import.
Handle subscription consent and contact hygiene
FlitStack reviews every Fieldy contact record for an email opt-in flag. Contacts without documented consent are flagged in the migration plan with one of three dispositions: subscribed (if consent exists elsewhere), pending (imports with double opt-in confirmation in Mailchimp), or excluded. We also run a deduplication pass — matching on email address — to prevent duplicate subscribers in Mailchimp, and flag hard bounces or invalid email formats. Your team approves the consent disposition list before migration commits.
Run sample migration and field-level diff
A representative sample — typically 200–500 Fieldy contact records — migrates into Mailchimp first. FlitStack generates a field-level diff comparing source values in Fieldy against the corresponding subscriber fields in Mailchimp, including merge fields and Group membership. You verify that consent statuses are correct, tags are applied, and custom field values are populated as expected. Any field mapping corrections are adjusted before the full run commits. This sample validates the entire pipeline end-to-end.
Execute full migration with delta-pickup window
The full Fieldy contact and company dataset migrates into Mailchimp using Mailchimp's API with batch operations for efficiency. A delta-pickup window of 24–48 hours runs after the initial load, capturing any Fieldy contacts created or updated during the cutover window. FlitStack generates a reconciliation report comparing total migrated subscribers, subscribed/pending/excluded counts, and tag application totals. One-click rollback is available if the reconciliation reveals discrepancies. Non-transferable Fieldy objects (Job, Invoice, Quote) are delivered as separate reference CSVs with complete field schemas.
