Overview
Moving from FreeCRM to Mailchimp is a data-model simplification: FreeCRM's CRM objects (Contacts, Companies, Leads, Deals, Activities) have no direct Mailchimp equivalents except Contacts which map to audience Members. We extract FreeCRM data via CSV export (no public API exists), normalize account-specific template fields into typed Mailchimp merge fields, preserve FreeCRM tags as audience tags, and flag any Company, Deal, and Activity data that cannot map to Mailchimp's audience-centric model. Mailchimp has no pipeline, deal, or owner-assignment structure; we document these gaps and deliver a written map of every FreeCRM workflow and automation requiring manual rebuild in Mailchimp's automation builder post-migration. Workflows, automations, and form definitions do not migrate as code.
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 FreeCRM 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.
FreeCRM
Contact
Mailchimp
Member
1:1FreeCRM Contacts map to Mailchimp Members in the primary audience. Standard fields (first name, last name, email, phone, address) map to Mailchimp's corresponding standard member fields. We preserve the FreeCRM contact ID in a custom merge field freecrm_id__c for audit and reconciliation. Email status (subscribed, unsubscribed, cleaned) is derived from FreeCRM's contact status field at migration time.
FreeCRM
Company
Mailchimp
Tag or Note
1:manyFreeCRM Company records do not have a direct Mailchimp equivalent. We offer two strategies during scoping: (1) add Company name as a Mailchimp tag on each Member linked to that Company, enabling segment-based filtering by account; or (2) store Company name, domain, and industry as merge fields on the Member record. The customer chooses. Industry classification becomes a merge field regardless of tag strategy for segmentation purposes.
FreeCRM
Lead
Mailchimp
Member (segment-tagged)
1:1FreeCRM Leads migrate as Members with a lead_status tag applied. We preserve the FreeCRM lead source in a merge field lead_source__c and lifecycle stage in lifecycle_stage__c if those fields exist in the account's template set. Leads without an email address cannot migrate to Mailchimp because every Member requires an email address; we flag these records in the reconciliation report.
FreeCRM
Tag
Mailchimp
Tag
1:1FreeCRM tags export as comma-separated values on Contact and Company records. We split them into individual tags and apply each to the corresponding Member in the destination Mailchimp audience. Tags are preserved verbatim; Mailchimp tags are case-sensitive and unlimited per audience. If a tag name conflicts with a Mailchimp system tag (unsubscribe, clean, bounced), we prefix it with freecrm_ to avoid override.
FreeCRM
Custom Field
Mailchimp
Merge Field
lossyFreeCRM template-driven custom fields vary per account. We inventory every unique custom field across all active templates during discovery, type each field (text, number, date, checkbox, dropdown), then create corresponding Mailchimp merge fields in the audience before import. Text merge fields in Mailchimp are capped at 255 characters; FreeCRM text fields exceeding this limit are truncated with a flag in the reconciliation report. Dropdown values in FreeCRM map to radio button or dropdown merge fields in Mailchimp.
FreeCRM
Deal
Mailchimp
Not migrated
1:1FreeCRM Deals have no equivalent in Mailchimp. Pipeline stages, deal amounts, expected close dates, and deal owner assignment cannot map to Mailchimp's audience model. We extract deal data as a CSV export separate from the audience migration and deliver it as a standalone file for the customer to use in a dedicated CRM or spreadsheet. Deal records are documented in the migration inventory with a recommendation to evaluate Mailchimp's integrations with CRMs (Salesforce, HubSpot, Zoho) if pipeline tracking is required post-switch.
FreeCRM
Activity
Mailchimp
Not migrated
1:1FreeCRM Activities (calls, emails, meetings, tasks) have no Mailchimp equivalent. Mailchimp tracks opens, clicks, unsubscribes, and purchases as engagement events on Member records, but FreeCRM's task-level activity history (subject, body, timestamps, disposition) cannot map. We preserve activity data as a separate CSV export delivered with the migration package and flag it for the customer's admin to evaluate whether any records warrant manual entry into Mailchimp contact notes.
FreeCRM
Pipeline
Mailchimp
Not migrated
1:1FreeCRM Kanban pipeline stages (account-defined text values) cannot migrate to Mailchimp because Mailchimp has no pipeline or deal-stage concept. We extract the pipeline stage list during discovery, document each stage with its probability percentage, and deliver this as a written pipeline map for the customer to use when selecting a CRM that integrates with Mailchimp (Salesforce, HubSpot, or Zoho all have Mailchimp integrations).

Migration approach
Discovery and template inventory
We request full CSV exports from FreeCRM covering Contacts, Companies, Leads, Deals, Activities, and any custom template records. We inventory every active FreeCRM template, catalog each field with its data type, and identify which fields map directly to Mailchimp standard fields versus custom merge fields. We also extract unsubscribe and bounce lists separately for suppression import. This phase produces a written field map and a FreeCRM object inventory noting which objects have Mailchimp equivalents and which do not.
Mailchimp audience setup and merge field creation
We create or confirm the destination Mailchimp audience and configure merge fields for every FreeCRM custom field that has a valid Mailchimp type mapping. We apply the 255-character limit to text fields, map FreeCRM dropdown values to Mailchimp merge field options, and set field labels that match the original FreeCRM field names for admin recognition. If the contact count exceeds the merge field limit for the chosen Mailchimp plan, we present consolidation options and confirm a plan upgrade with the customer before proceeding.
Suppression list import
We import the FreeCRM unsubscribe and bounce list into Mailchimp as a suppression list before any Member records are added. This step is required to prevent Mailchimp from sending to contacts who previously opted out and to protect sender reputation scores. We also import any FreeCRM contacts marked as cleaned or recycled through the suppression pipeline.
Contact and Lead migration
We import FreeCRM Contacts as Mailchimp Members using the field map built in discovery. Email addresses serve as the unique identifier. We apply FreeCRM tags from the comma-separated tag field on each contact and store owner names, lifecycle stages, and lead sources as merge fields. FreeCRM Leads migrate as Members with a lead_status tag applied. Records without a valid email address are logged to the reconciliation report and excluded from migration.
Company and Deal data export
FreeCRM Companies and Deals do not migrate to Mailchimp objects. We export these as standalone CSV files delivered alongside the Mailchimp audience migration. For Companies, we include the Company-to-Contact linkage so the customer can reconstruct relationships in a new CRM. For Deals, we include stage, amount, close date, and owner. We document these files in the migration inventory with guidance on importing them to a dedicated CRM if needed.
Cutover, validation, and workflow handoff
We validate the Mailchimp audience by spot-checking record counts, tag distribution, and merge field completeness against the FreeCRM export. We deliver the written workflow inventory documenting every FreeCRM automation and follow-up sequence with its trigger and recommended Mailchimp Customer Journey equivalent. We do not rebuild automations as Mailchimp Customer Journeys inside the migration scope. We support a three-day post-migration review window where the customer can flag any missing contacts or field mapping errors.
