Overview
Moving from VAIL-CRM to Mailchimp is a deliberate simplification: you are consolidating from a full CRM with sales force, marketing automation, and service automation modules into an email marketing platform with audience management. The migration centers on Contacts and Companies mapping to Mailchimp Audience members, with VAIL-CRM Deals, Pipelines, and Service Tickets having no Mailchimp equivalent and requiring either archival or manual reconstruction outside the platform. We use Mailchimp's API or CSV import to load contacts, preserving the original VAIL-CRM owner and company relationships as Mailchimp tags. Email engagement history migrates to campaign activity notes, but Mailchimp Automations are not code-compatible with VAIL-CRM Workflows and require documented recreation. We contact Velosi directly to confirm export capabilities given the lack of public API documentation, and we fall back to CSV export with manual field validation where API access is unavailable.
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 VAIL-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.
VAIL-CRM
Contact
Mailchimp
Mailchimp Audience Member
1:1VAIL-CRM Contacts map directly to Mailchimp Audience members. Email address is the primary key for deduplication. First name, last name, phone, and social media identifiers migrate to standard Mailchimp merge fields (FNAME, LNAME, PHONE). We set the member status based on VAIL-CRM subscription or opt-in status. Any VAIL-CRM contact without an email address is flagged in a reconciliation report because Mailchimp requires an email address for every Audience member.
VAIL-CRM
Company
Mailchimp
Mailchimp Tag or Group
1:manyVAIL-CRM Company records have no direct Mailchimp equivalent. We map Company names to Mailchimp Tags applied to each Contact member, and optionally to a Group Category (e.g., 'Company') with Group values for each distinct company name. Tags are preferred for simple company tracking; Groups are recommended if the customer needs to segment by company for campaign targeting. The customer chooses the strategy during scoping.
VAIL-CRM
Deal
Mailchimp
Archive or Tag
1:1VAIL-CRM Deals have no Mailchimp equivalent. We do not migrate Deals as live records. We offer two options: (1) export Deals as a CSV archive delivered alongside the migration, or (2) map Deal stage names to Tags on the associated Contact records so that sales pipeline context is preserved as a tag reference. The customer selects the approach during scoping. Opportunity values and close dates do not transfer to Mailchimp.
VAIL-CRM
Pipeline
Mailchimp
Not migratable
lossyVAIL-CRM Pipeline configurations and stage sequences have no Mailchimp equivalent. Mailchimp does not support deal pipelines, stage probabilities, or sales process management. We document the pipeline schema (stage names, order, probabilities) in a written deliverable so the customer's admin can reference it if they later move to a full CRM.
VAIL-CRM
Engagement: Email
Mailchimp
Mailchimp Campaign Activity Note
1:1VAIL-CRM email engagement records migrate to Mailchimp as campaign activity notes on the relevant Audience member. The email subject, timestamp, and engagement status (opened, clicked) are preserved as merge field data or as a tagged note. We use the Mailchimp Members API to add activity context. Note that Mailchimp tracks its own engagement data post-migration; historical VAIL-CRM engagement data is appended as historical context rather than native Mailchimp analytics.
VAIL-CRM
Engagement: Note
Mailchimp
Mailchimp Note
1:1VAIL-CRM Notes migrate to Mailchimp Notes attached to the relevant Audience member. We resolve the note's related Contact in VAIL-CRM and attach the note to the corresponding Mailchimp member by email match. Note timestamps are preserved. Attachments stored in VAIL-CRM Notes are exported as separate files and delivered alongside the migration.
VAIL-CRM
Marketing Automation Workflow
Mailchimp
Documentation
lossyVAIL-CRM Marketing Automation workflows do not migrate to Mailchimp Automations. Mailchimp Automations use a different trigger-and-action model (Customer Journey builder with predefined triggers). We deliver a written inventory of every active VAIL-CRM workflow with its trigger conditions, action sequence, and delay rules, mapped to a recommended Mailchimp Automation template. The customer's admin rebuilds workflows in Mailchimp manually or with assistance from a Mailchimp partner.
VAIL-CRM
Custom Fields
Mailchimp
Mailchimp Merge Fields or Tags
1:1VAIL-CRM custom fields on Contact and Company objects map to Mailchimp merge fields. Mailchimp Standard allows up to 30 merge fields per Audience; Mailchimp Premium allows up to 80. For fields exceeding the limit, we map values to Tags applied to the relevant member. Date fields, numeric fields, and picklist fields are mapped to text merge fields by default. Multi-select fields are mapped to comma-separated text or to Mailchimp Groups.
VAIL-CRM
Service Automation Ticket
Mailchimp
Archive or External System
1:1VAIL-CRM Service Automation tickets (support cases) have no Mailchimp equivalent. Mailchimp is an email marketing platform and does not manage support tickets. We export tickets as a CSV archive with status, assignment, and conversation history. If the customer uses a separate helpdesk (Zendesk, Freshdesk, HubSpot Service Hub), we can map ticket data to that system as a separate migration scope.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
VAIL-CRM gotchas
Limited public API documentation requires direct inquiry with Velosi for export capabilities
Multi-module data isolation requires identifying which components are active
CRM migration complexity underestimated without discovery phase
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Discovery and module audit
We audit the VAIL-CRM instance to identify which modules are active: sales force automation, marketing automation, and service automation. We document the custom field schema for Contact, Company, Deal, and any active pipeline objects. We contact Velosi directly to confirm API access and export capabilities. We extract a 50-100 record sample to validate field mapping and identify data quality issues (missing emails, duplicate companies, null custom fields). The discovery output is a written scope document confirming export method, object mapping, and any field reduction requirements.
Mailchimp audience setup and field planning
We create the Mailchimp audience structure during or before migration. This includes configuring the audience name, setting up Group Categories (e.g., Company, Industry, Owner), and creating merge fields for each VAIL-CRM custom field that fits within Mailchimp's field limits. For any fields exceeding the limit, we define a tag-based fallback strategy. We set default opt-in and opt-out settings aligned with VAIL-CRM subscription statuses.
Contact and company extraction
We extract all Contacts from VAIL-CRM via API (where available) or CSV export. Email address is the primary deduplication key. We extract Company records in parallel and build a company-to-contact mapping table. Owner relationships (sales rep assignments) are extracted for mapping to Mailchimp Tags if the customer wants owner context preserved on audience members. Duplicate records (same email, multiple entries) are flagged for manual review.
Data transformation and field mapping
We transform VAIL-CRM field values to Mailchimp merge field formats. Date fields are converted to Mailchimp-compatible date format. Multi-select fields are joined with commas or mapped to Groups. Phone numbers are normalized to a consistent format. Company names are mapped to Tags or Groups per the customer's selected strategy. We run the transformation on the 50-100 record discovery sample and share a validation report before running the full migration.
Audience import and validation
We import Contacts into Mailchimp via the Mailchimp Members API or CSV upload, applying Tags and Group assignments during import. We run a row-count reconciliation (contacts extracted vs. members imported) and a field-density check (merge fields populated vs. null). Any import errors (missing email, invalid format, field limit exceeded) are logged and resolved in a second-pass import. The customer spot-checks 20-30 records against the VAIL-CRM source.
Handoff and automation documentation
We deliver the migration handoff package: row-count reconciliation report, CSV archive of Deals and Service Tickets (if applicable), written automation inventory for VAIL-CRM workflows with Mailchimp Customer Journey equivalents, and the custom field mapping document. We do not rebuild VAIL-CRM workflows in Mailchimp; that work is the customer's admin responsibility or a separate Mailchimp implementation engagement. We support a three-day hypercare window for reconciliation issues raised during initial Mailchimp sends.
