Overview
Virtual Case Management stores client records for nonprofit and human services organizations — tracking demographics, program enrollments, referral sources, service histories, and caseworker assignments. The platform uses a flat contact record with custom fields for program-specific data. Mailchimp is an email marketing platform organized around audiences, contacts, tags, and merge fields. Migrating from VCM to Mailchimp means extracting client contact data (names, emails, phone numbers, addresses) and mapping program enrollment status, referral sources, and client tags into Mailchimp's tag-based segmentation or custom merge fields. VCM's case notes, document attachments, referral chain data, and service history records have no Mailchimp equivalent and must be documented separately or exported to a document repository. We use VCM's API export and Mailchimp's bulk import API to move contact records, applying tag-based value mappings for program enrollment and referral source fields. A 24–48 hour delta pickup window captures any new client intakes or contact updates made during the cutover. FlitStack does not migrate VCM workflows, automated intake rules, or case assignment logic — those constructs are destination-side and must be rebuilt in Mailchimp's automation tools.

Object mapping
Each row shows how a Virtual Case Management 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.
Virtual Case Management
Client / Contact Record
Mailchimp
Mailchimp Contact (Audience Member)
1:1VCM's client record maps directly to a Mailchimp audience member. Every client with a valid email address becomes a Mailchimp subscriber. Clients without email addresses are flagged for manual review — your team decides whether to include them or hold them in a separate VCM export.
Virtual Case Management
Client Email Address
Mailchimp
Mailchimp EMAIL field
1:1The primary email address on a VCM client record maps directly to Mailchimp's EMAIL field, which is the unique identifier for each audience member. Mailchimp enforces email format validation; invalid addresses are flagged and excluded from the import. During the pre-migration data audit, we identify malformed email addresses and provide a report so your team can correct or remove them before the import process begins.
Virtual Case Management
Client First Name / Last Name
Mailchimp
Mailchimp FNAME / LNAME merge fields
1:1VCM first name and last name fields map to Mailchimp's standard FNAME and LNAME merge fields, which are automatically available in every Mailchimp audience. These power personalization tokens like 'Dear *|FNAME|*' in email templates, allowing you to address recipients by name in your campaigns. If VCM stores names in a single field rather than separate first and last name fields, we split them during the transformation process before loading into Mailchimp.
Virtual Case Management
Program Enrollment Status
Mailchimp
Mailchimp Tag or Merge Field
1:1VCM program enrollment checkboxes or pick-lists (e.g., 'Housing Program', 'Food Bank', 'Youth Services') map to Mailchimp tags applied per enrollment. This preserves the multi-program client scenario — a client enrolled in three programs receives three tags in Mailchimp, enabling segment-based campaigns.
Virtual Case Management
Referral Source
Mailchimp
Mailchimp Tag or Merge Field
1:1VCM referral source pick-list values (e.g., 'Hospital', 'School', 'Self-Referral', 'Court') map to Mailchimp tags or a custom merge field (REFERRAL_SOURCE). Value-by-value mapping ensures each referral category is represented in Mailchimp's segmentation UI. During planning, your team chooses whether referral sources should be tags (for flexible segment building) or a structured merge field (for reporting dashboards). We document all pick-list values from VCM to ensure no referral category is lost in translation.
Virtual Case Management
Client Phone Number
Mailchimp
Mailchimp PHONE merge field
1:1VCM phone number fields map to Mailchimp's PHONE merge field, which is available by default. Note that Mailchimp does not use phone numbers for SMS campaigns unless your Mailchimp plan includes mobile optimization and you separately configure SMS opt-in. If you anticipate using SMS outreach in the future, we can flag phone numbers for mobile marketing compliance during the migration, ensuring you're prepared to activate SMS features when your plan allows.
Virtual Case Management
Client Address (Street, City, State, Zip)
Mailchimp
Mailchimp ADDRESS merge field
1:1VCM address fields map to Mailchimp's structured ADDRESS merge field, which stores street, city, state, and zip as sub-fields. This enables Mailchimp's postal merge feature for physical mail campaigns if your nonprofit uses that channel. For organizations that send printed newsletters, event invitations, or donation acknowledgments via postal mail, the ADDRESS merge field allows personalized letter generation directly from Mailchimp without manual label creation.
Virtual Case Management
Caseworker / Assigned Staff
Mailchimp
Mailchimp Merge Field (CASEWORKER)
1:1VCM's assigned caseworker field has no native Mailchimp equivalent. We create a CASEWORKER merge field on the Mailchimp audience and populate it with the staff member's name or email. This lets you segment by assigned caseworker if needed for internal coordination emails.
Virtual Case Management
Case Notes and Service History
Mailchimp
No Equivalent in Mailchimp
1:1VCM case notes, service entries, and interaction history are narrative records with no Mailchimp equivalent. Mailchimp is not a case management tool. We export these as a separate CSV and document their location; your team manages them in VCM or an alternative system if you maintain both platforms temporarily.
Virtual Case Management
Client Intake Date
Mailchimp
Mailchimp Merge Field (INTAKE_DATE)
1:1VCM's client intake date maps to a custom INTAKE_DATE merge field in Mailchimp (date type). This preserves enrollment recency for segmentation — useful for welcome series triggers based on how long a client has been in the system. You can create segments for 'clients enrolled in the last 30 days' or 'clients active for over a year,' enabling time-based automation that delivers tailored outreach to different client cohorts based on their tenure with your organization.
Virtual Case Management
VCM Document Attachments
Mailchimp
No Equivalent in Mailchimp
1:1VCM stores consent forms, referral letters, and case documents as file attachments. Mailchimp does not have a document repository. We flag attachments for separate export and storage; if documents need to be referenced in emails, they must be hosted externally and linked.
Virtual Case Management
VCM Custom Fields (Program-Specific)
Mailchimp
Mailchimp Merge Fields
1:1VCM custom fields created for program-specific data (e.g., 'Housing Voucher Status', 'Income Bracket', 'Household Size') map to Mailchimp custom merge fields. Each field requires creation in Mailchimp before import; we deliver a merge field setup plan as part of the migration package.

Migration approach
Conduct pre-migration data audit and field mapping plan
FlitStack AI extracts a full contact export from Virtual Case Management via API, profiles the data for invalid emails, duplicate records, and blank required fields, and identifies all active custom fields. We deliver a field mapping plan showing which VCM fields map to Mailchimp merge fields (created as part of setup), which become tags, and which have no Mailchimp equivalent and will be exported separately. Your team approves the plan before any data moves.
Create Mailchimp audience and configure merge fields
We create a new Mailchimp audience (or use an existing one per your direction) and pre-create all custom merge fields needed for the migration — CASEWORKER, INTAKE_DATE, STATUS, and any program-specific fields identified in the audit. Tags are pre-configured with naming conventions for program enrollment and referral source. This step runs in parallel with your VCM team continuing normal operations.
Run sample migration with field-level verification
A representative sample (typically 100–500 records) migrates first, loading into your Mailchimp audience. We generate a field-level diff report showing source VCM values against destination Mailchimp field values for every mapped field. You verify tag application for multi-enrollment clients, merge field population for custom fields, and overall contact count in Mailchimp versus VCM total. No full migration commits until this sample passes your sign-off.
Execute full migration with delta-pickup window
The full VCM contact list migrates via Mailchimp's bulk import API. A delta-pickup window of 24–48 hours captures any new client intakes or email updates made during the cutover. After the window closes, we run a final reconciliation report comparing total contacts, tag counts, and merge field completeness against the VCM source. FlitStack AI provides a rollback-capable audit log; if reconciliation fails beyond agreed tolerances, we can re-import from the VCM snapshot.
