Overview
improveit 360 is a purpose-built CRM for residential remodelers and replacement contractors, managing leads, quotes, appointments, and project schedules in a single platform. Mailchimp is an audience-first email marketing platform that stores contacts as subscribers within Audiences, using merge fields and tags to hold custom data. The two platforms share only a surface-level contact model: name, email, phone, and address. Everything else in improveit 360 — deals, quotes, pipeline stages, project records, appointment schedules, task queues, and custom CRM fields — has no equivalent in Mailchimp's flat subscriber model. FlitStack AI migrates contacts and leads with their standard fields, preserves original timestamps and owner emails, suppresses unsubscribed records to protect deliverability, and maps improveit 360 custom properties to Mailchimp merge fields. Your improveit 360 automations, sequences, appointment workflows, and quote templates must be rebuilt manually in Mailchimp. We export the data via improveit 360's API, validate subscriber counts against your Mailchimp plan limits, and run a sample import before committing the full cutover.
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 improveit 360 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.
improveit 360
Contact
Mailchimp
Subscriber
1:1Improveit 360 contacts migrate as Mailchimp subscribers. Each contact's email address becomes the subscriber key. Duplicate emails are flagged before import and suppressed if unsubscribed in Mailchimp.
improveit 360
Lead
Mailchimp
Subscriber
1:1Improveit 360 leads also map to Mailchimp subscribers. Leads and contacts are merged into a single subscriber list; a SOURCE_IMPROVEIT360 field marks the origin record type for segmentation.
improveit 360
Company
Mailchimp
Merge Field (COMPANY_NAME)
1:1Mailchimp has no native company object. Improveit 360 company names map to a COMPANY_NAME merge field on the subscriber record. If a contact has multiple companies, the primary company is used.
improveit 360
Quote
Mailchimp
No Equivalent
1:1Improveit 360 quotes have no Mailchimp equivalent. Quote IDs and amounts can be stored as custom merge fields (QUOTE_ID, QUOTE_AMOUNT) for reference, but the quote documents themselves are exported as a separate CSV for manual recordkeeping.
improveit 360
Project
Mailchimp
No Equivalent
1:1Improveit 360 project records (job sites, contract status, project stages) have no Mailchimp counterpart. Project status can be stored as a merge field or tag, but the project management workflow must be rebuilt in a separate tool.
improveit 360
Appointment
Mailchimp
No Equivalent
1:1Improveit 360 appointment records (scheduled visits, measurements, installations) do not migrate. Appointment history is exported as a CSV. Mailchimp's automation triggers can recreate reminder email flows if scheduling is managed elsewhere.
improveit 360
Task
Mailchimp
No Equivalent
1:1Improveit 360 task records (follow-up reminders, call logs, to-dos) have no Mailchimp equivalent. Task owner emails can be mapped to Mailchimp tags for internal routing, but task management must continue in a separate system.
improveit 360
Lead Source
Mailchimp
Merge Field (LEAD_SOURCE)
1:1Improveit 360 lead source values (Google Ads, referral, walk-in) map to a LEAD_SOURCE merge field. This field can drive Mailchimp segment filters for source-based drip campaigns.
improveit 360
Lifecycle/Status
Mailchimp
Tag or Merge Field
1:1Improveit 360 lifecycle stages (New Lead, Quote Sent, Under Contract, Job Scheduled, Completed) map to Mailchimp tags or a LIFECYCLE_STATUS merge field. Tags allow more flexible segmentation than pick-list merge fields.
improveit 360
Owner
Mailchimp
Merge Field (OWNER_EMAIL) + Tag
1:1Improveit 360 owner (sales rep) email addresses map to an OWNER_EMAIL merge field. The owner name can be stored as a tag so each sales rep can filter their own subscriber list within Mailchimp.
improveit 360
Unsubscribe List
Mailchimp
Suppression List
1:1Improveit 360 unsubscribed contacts are exported and uploaded to Mailchimp as a suppression list before the main import. This prevents accidentally mailing people who opted out in the source CRM, protecting deliverability.
improveit 360
Attachment/File
Mailchimp
No Equivalent
1:1Improveit 360 files attached to records (photos, contracts, proposals) have no Mailchimp equivalent. File URLs can be stored as merge fields if hosted externally, but the files themselves do not migrate.

Migration approach
Extract improveit 360 contacts and leads via API
FlitStack AI authenticates to your improveit 360 instance using API credentials and exports all Contact and Lead records with their standard fields and custom properties. We pull owner emails, lead sources, lifecycle stages, and unsubscribed flags. The export runs in batches to respect improveit 360's API rate limits and generates a manifest showing record counts by type.
Create Mailchimp merge fields before import
Based on the improveit 360 field inventory, we pre-create Mailchimp merge fields for all non-standard mappings (COMPANY_NAME, LEAD_SOURCE, LIFECYCLE, JOIN_DATE, QUOTE_AMOUNT, PROJECT_STAGE, etc.). Merge field names are abbreviated to comply with Mailchimp's 30-character limit. Tags for owner names and lifecycle stages are also pre-created so segmentation is ready at import time.
Upload suppression list and deduplicate
Improveit 360 unsubscribed contacts are exported and uploaded to Mailchimp as a suppression list before the main subscriber import. We also run email deduplication across the combined lead and contact set — if the same email appears in both improveit 360 Leads and Contacts, we merge the records and preserve all field values. Duplicate email addresses across different contacts are flagged for your review before the import commits.
Run a sample import with field-level validation
A representative slice of 200–500 records imports into your Mailchimp staging Audience first. We verify that merge fields populated correctly, tags applied as expected, the SOURCE_IMPROVEIT360 marker is present, and unsubscribed records were correctly excluded. A field-level diff report is shared with you for sign-off before the full migration runs.
Full import with delta-pickup window
The complete contact and lead set imports into your Mailchimp Audience. A delta-pickup window (24–48 hours) captures any new records or email changes made in improveit 360 during the cutover. We generate an audit log of every imported subscriber with source record IDs and timestamps. One-click rollback is available if reconciliation finds unexpected discrepancies.
