Overview
Migrating from Variable Soft CRM to Mailchimp is a deliberate platform-type change: VSCRM is a full relationship CRM with Leads, Contacts, Companies, Deals, Pipelines, and Workflow Automations; Mailchimp is a contact-centric email marketing platform with Audiences, Tags, Campaigns, and customer journeys. The migration is scoped to what Mailchimp can receive—Contacts and Leads from VSCRM become Mailchimp audience members, Company records become Tags or merge field values, and Deal associations become Notes or Tags on the contact record. VSCRM Workflow Automations, Pipelines, custom objects, and engagement history (calls, emails, meetings) have no Mailchimp equivalent and cannot migrate. We deliver a written automation inventory for manual rebuild and a deduplication pass against existing Mailchimp audiences before import to prevent duplicate records.
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 Variable Soft CRM 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.
Variable Soft CRM
Contact
Mailchimp
Audience Member
1:1VSCRM Contact records map to Mailchimp audience members. The contact's email address is the Mailchimp subscriber hash key for deduplication. First name, last name, phone, and lifecycle stage migrate as standard Mailchimp merge fields (FNAME, LNAME, PHONE, LIFEycle). We validate email format and suppress invalid addresses before import to protect deliverability metrics.
Variable Soft CRM
Lead
Mailchimp
Audience Member
1:1VSCRM Lead records map to Mailchimp audience members. Mailchimp has no Lead object, so unqualified prospects migrate as standard audience members. We flag any Lead records with status values that indicate disqualified or spam sources so they can be suppressed at import rather than added to the active audience.
Variable Soft CRM
Company/Account
Mailchimp
Tags or Merge Field (COMPANY)
lossyVSCRM Company records do not have a direct Mailchimp equivalent. We map the company name to the COMPANY merge field on each associated Contact's audience member record. If the customer uses company as a segmentation signal, we create a Tag per unique company name and apply it to all members from that company. Company-level custom fields (industry, size, region) cannot migrate to Mailchimp because Mailchimp lacks a custom fields API beyond standard merge fields.
Variable Soft CRM
Deal
Mailchimp
Note or Tag (no CRM equivalent)
1:1VSCRM Deals carry value, stage, owner, expected close date, and pipeline. Mailchimp has no deal or opportunity object. We document the active deal count, total pipeline value, and stage distribution in a written deal inventory delivered alongside migration. If the customer wants deal context preserved on the contact record, we apply a Tag matching the deal name and stage to the associated Contact's audience member record, but this is informational only and not a functional CRM link.
Variable Soft CRM
Pipeline
Mailchimp
Not migratable
1:1VSCRM Pipelines (custom stage sequences per line of business) have no Mailchimp equivalent. Mailchimp's segmentation is tag-based and campaign-based, not pipeline-based. We document the pipeline names and stage labels in the automation inventory so the customer's admin can decide whether to represent pipeline context as tags or to retire the pipeline concept entirely in favor of Mailchimp's audience journey model.
Variable Soft CRM
Activity (calls, emails, meetings, tasks)
Mailchimp
Not migratable
1:1VSCRM Activity records (call logs, email content, meeting records, task completions) are linked to Contacts and Deals. Mailchimp does not store activity history for individual contacts beyond campaign-level engagement metrics (opens, clicks, unsubscribes) which are generated by Mailchimp sends, not imported. We cannot migrate VSCRM activity content. Campaign engagement history generated inside Mailchimp post-migration is tracked natively.
Variable Soft CRM
Custom Fields
Mailchimp
Merge Fields (limited to 255 chars)
lossyVSCRM custom fields on Contacts and Companies are discovered from the customer's export file. Mailchimp supports text, number, date, phone, address, and birthday merge field types, each capped at 255 characters. Long-text custom fields in VSCRM are truncated or dropped. We map each VSCRM custom field to the nearest Mailchimp merge field type during the transform pass and flag any truncation above 200 characters as a data-loss risk for customer review before import.
Variable Soft CRM
Workflow Automations
Mailchimp
Not migratable
1:1VSCRM Workflow rules are server-side and non-exportable. We do not migrate automations. We document every active VSCRM workflow rule (trigger, conditions, actions) during discovery and deliver a written rebuild checklist so the customer's admin can reconstruct equivalent logic in Mailchimp Customer Journeys if they hold the required plan tier. Mailchimp Customer Journeys are available on Essentials and above; the free Standard plan does not include journey automation.

Migration approach
VSCRM export coordination
We confirm the customer's VSCRM tier and verify export availability. VSCRM does not expose a public API, so we request a full data export from the customer's instance—typically a CSV bundle covering Contacts, Leads, Companies, Deals, and Pipeline definitions. If the customer is on VSCRM's free tier and the export tool is not self-serve, we escalate to VSCRM support on the customer's behalf. We validate the export against reported record counts and flag any missing objects or truncated fields before proceeding.
Mailchimp audience audit and plan check
We audit the destination Mailchimp account for existing audience structure, applied tags, merge field definitions, and plan tier. If the customer holds a free or Standard plan, we confirm that Customer Journeys are not included so the automation rebuild checklist reflects the correct Mailchimp capability set. We run the pre-import deduplication pass against the existing audience and deliver a duplicate-resolution report for the customer to approve before import begins.
Schema mapping and transform design
We design the field-level mapping from VSCRM export columns to Mailchimp merge fields. Contact and Lead records map to audience members. VSCRM Company name maps to the COMPANY merge field or a Tag per company. Lifecycle stage from VSCRM maps to a TAG on the audience member record. Custom fields are mapped to the nearest Mailchimp merge field type and truncated at 255 characters with a truncation report delivered for review. Deals and Pipelines are documented in the deal inventory rather than mapped to Mailchimp fields.
Sandbox import and reconciliation
We run a test import into a new or staging Mailchimp audience using a representative data sample (typically 10% of records or 500 records, whichever is larger). We validate subscriber hash generation, merge field population, tag application, and duplicate handling. The customer spot-checks 25-50 imported records against the VSCRM source and signs off the mapping before production import proceeds.
Production import with deduplication
We run the full production import into the active Mailchimp audience. The import uses the approved mapping, applies the deduplication logic from the pre-import pass, and sets subscriber status based on VSCRM contact lifecycle (active contacts import as subscribed; bounced or unsubscribed VSCRM records import as unsubscribed or suppressed). Each import run emits a row-count reconciliation report. If the customer holds Essentials or Standard, we apply the documented Tags from the company and lifecycle mapping.
Cutover, delivery, and automation handoff
We freeze VSCRM write access on cutover date, run a final delta import of any records modified during the migration window, and confirm final audience counts match the VSCRM source. We deliver the migration package: the Mailchimp audience with verified member counts, the deal inventory document, and the VSCRM workflow rebuild checklist. We do not rebuild VSCRM automations as Mailchimp Customer Journeys inside the migration scope; that is a separate engagement or an internal admin task.
