Overview
MeasureSquare and Mailchimp serve fundamentally different functions, which shapes every migration scope. MeasureSquare CRM stores project management data — contacts, companies, projects, estimates, product catalogs, and pipeline stages — alongside industry-specific custom fields for the flooring trade. Mailchimp is an email marketing platform whose data model centers on audiences, contacts, tags, and automations. FlitStack AI migrates the contact and company data that both platforms share (names, emails, phones, addresses, company associations) and translates MeasureSquare-specific fields into Mailchimp custom contact properties or audience tags. Projects, estimates, work orders, product catalogs, and purchase orders have no Mailchimp equivalent and do not migrate. MeasureSquare workflow automations — pipeline-stage triggers, estimate notifications, approval sequences — do not carry over and must be rebuilt in Mailchimp. We extract data via the MeasureSquare Cloud API, map fields to Mailchimp's import format, and deliver a pre-migration field-level diff so you can verify every custom field before your audience goes live. Delta-pickup captures any new contacts created in MeasureSquare during the cutover window.
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 MeasureSquare 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.
MeasureSquare
Contact
Mailchimp
Mailchimp Contact
1:1MeasureSquare contacts map directly to Mailchimp contacts in the target audience. Email address is the unique identifier — contacts without a valid email are flagged before migration since Mailchimp requires an email address for every subscriber. Duplicate emails are resolved by most-recently-modified date, retaining the latest MeasureSquare contact record.
MeasureSquare
Company
Mailchimp
Mailchimp Contact (company property)
1:1MeasureSquare companies map to a custom contact field or merged text property in Mailchimp (e.g., 'Company Name: Acme Flooring'). Mailchimp does not have a separate Company/Account object. For contacts with multiple associated MeasureSquare companies (N:1 or N:N), we preserve the primary company and surface others as comma-separated text or tags.
MeasureSquare
Pipeline / Stage
Mailchimp
Mailchimp Segment / Tag
1:1MeasureSquare pipeline stages (Lead, Prospect, Bid Sent, Awarded, In Progress, Completed) have no native Mailchimp equivalent. We create Mailchimp segments keyed by pipeline stage name and apply them at import time. Stage names are mapped value-by-value, and contacts are automatically placed into the correct segment based on their MeasureSquare pipeline stage.
MeasureSquare
Lifecycle Stage
Mailchimp
Mailchimp Custom Field
1:1MeasureSquare lifecycle stages (Lead, Prospect, Customer, Inactive) require a custom contact field in Mailchimp — typically a pick-list field named 'MS_Lifecycle_Stage'. We create the custom field before import and map every contact's lifecycle value. This field can then drive Mailchimp segments for lifecycle-based email sequences.
MeasureSquare
Deal / Estimate Amount
Mailchimp
Mailchimp Custom Field
1:1MeasureSquare deal amounts (estimated project value) migrate as a custom number field in Mailchimp — typically 'MS_Deal_Amount' — stored on the contact record. This lets you segment customers by estimated project size for targeted re-engagement campaigns. Values are preserved as the decimal amount from MeasureSquare.
MeasureSquare
Project / Job
Mailchimp
No equivalent
1:1MeasureSquare projects, work orders, purchase orders, and job costing records have no Mailchimp equivalent. Mailchimp is a contact and campaign platform, not a project management tool. These records are exported as a separate CSV report for your records. Projects cannot be represented as Mailchimp contacts or custom objects.
MeasureSquare
Product / Service Catalog
Mailchimp
Mailchimp Tag / Custom Text Field
1:1MeasureSquare product databases (flooring materials, stone slabs, labor rates, supplier SKUs) are not contacts and do not migrate as Mailchimp objects. For teams using MeasureSquare product data for marketing (e.g., product-interest tags on contacts), we extract product catalog entries and apply them as Mailchimp tags or custom text fields on the contact record.
MeasureSquare
Task / Activity
Mailchimp
No equivalent
1:1MeasureSquare tasks, activities, and estimator notes are not imported to Mailchimp. Mailchimp tracks engagement activities (email opens, clicks, unsubscribes) but not internal CRM tasks. Activity history from MeasureSquare is exported as a separate audit CSV and retained for your records.
MeasureSquare
Custom Properties
Mailchimp
Mailchimp Custom Fieldset
1:1Any MeasureSquare custom contact properties beyond the standard fields (e.g., 'Flooring Type Interest', 'Estimator Assigned', 'Referral Source', 'Warranty Status') are mapped to Mailchimp custom fields. We create a custom fieldset matching the MeasureSquare property types — text, number, date, or pick-list — and apply field names based on the source property names.
MeasureSquare
Attachment / File
Mailchimp
No equivalent
1:1MeasureSquare attachments (floor plan files, cut sheets, slab layout PDFs) are not imported to Mailchimp. Mailchimp's contact record does not support file attachments. We export a list of MeasureSquare file references with their associated contact IDs so you can maintain a link between contacts and their attached documents outside of Mailchimp.

Migration approach
Export MeasureSquare contacts and companies via Cloud API
FlitStack AI connects to the MeasureSquare Cloud REST API using your account credentials and extracts all contact and company records in JSON format. We pull standard fields (name, email, phone, address) and custom properties, and flag any contacts missing a valid email address — Mailchimp requires email for every subscriber. The export also captures lifecycle stage, pipeline stage, and deal associations per contact for downstream field mapping.
Create Mailchimp custom fieldset and verify domain authentication
Before importing data, we create the Mailchimp custom fieldset that mirrors your MeasureSquare custom properties — MS_Lifecycle_Stage, MS_Deal_Amount, MS_Pipeline_Stage, MS_Project_Name, and any industry-specific fields from your MeasureSquare CRM. We also verify DKIM, SPF, and DMARC records on your sending domain. If authentication is missing, we provide the exact DNS records to add and wait for DNS propagation before proceeding. This preparation ensures a smooth, accurate import process.
Map fields and run a sample import with field-level diff
Standard MeasureSquare fields (first name, last name, email, phone, address, company) map directly to Mailchimp contact properties. Custom MeasureSquare properties are mapped to the custom fieldset created in Step 2. We run a sample import of 100–500 records first and generate a field-level diff showing every source value alongside its Mailchimp destination value, so you can verify lifecycle stage mapping, company name mapping, and deal amount precision before the full audience is touched.
Run full import with delta-pickup and post-migration validation
The full contact list imports into your Mailchimp audience with custom field values applied. A delta-pickup window captures any new contacts created in MeasureSquare during the cutover. After import, we validate subscriber counts, custom field completeness, and segment membership (pipeline stage segments should reflect MeasureSquare stage values). You receive an audit log of every imported contact with its source MeasureSquare ID for traceability.
