CRM migration
Field-level mapping, validation, and rollback between Sales Journey and Mailchimp. We move data and schema; workflows are rebuilt natively in Mailchimp.

Overview
Moving from Sales Journey to Mailchimp is a migration from a sales CRM to an email marketing platform, not a like-for-like CRM replacement. Sales Journey organizes data around Contacts, Companies, Deals, Leads, and Activity history; Mailchimp organizes around Audiences (contacts), Tags, and Merge Fields. We migrate contacts with their core fields and associated tags, map company information into Mailchimp merge fields, and flag the structural gaps. Deals, Pipelines, Activity history, and Custom Objects have no Mailchimp equivalent and do not migrate. Workflows and automations are not code-compatible between platforms; we deliver a written inventory for the customer's admin to rebuild as Mailchimp Customer Journeys post-migration. Sparse Sales Journey API documentation means we may request a live data export from the platform UI during discovery rather than relying on published API references.
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 Sales Journey 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.
Sales Journey
Contact
Mailchimp
Audience Member
1:1Sales Journey Contacts migrate to Mailchimp Audience members. The primary matching key is email address. Standard fields (first name, last name, email, phone) map to Mailchimp FNAME, LNAME, EMAIL, and PHONE merge fields. Any Sales Journey contact with a missing or malformed email is flagged in the reconciliation report and held for customer review before import.
Sales Journey
Company/Account
Mailchimp
Merge Fields
1:manySales Journey Company records do not have a direct Mailchimp equivalent. We extract company name, industry, size, and address fields from Sales Journey and map them to custom Merge Fields on the Audience (COMPANY, INDUSTRY, COMPANY_SIZE). Multiple Sales Journey contacts associated with the same company will carry matching merge field values; we do not deduplicate contacts by company because Mailchimp operates at the individual subscriber level.
Sales Journey
Deal
Mailchimp
Not Migrated
lossySales Journey Deals have no Mailchimp equivalent. Mailchimp is an email marketing platform without deal management, pipeline stages, or opportunity tracking. We flag the existence of Deals in the scoping report and note that deal values, stages, probabilities, and owners do not transfer. The customer documents any deal context they wish to preserve (e.g., customer vs. prospect status) for manual tagging in Mailchimp.
Sales Journey
Lead
Mailchimp
Audience Member (with tag)
1:1Sales Journey Leads migrate to Mailchimp Audience members with a LEAD tag applied. Any lead status or lead score fields from Sales Journey are preserved as Merge Fields (LEAD_STATUS, LEAD_SCORE). We do not create a separate Lead object in Mailchimp because Mailchimp has a unified contact model. The customer decides whether leads and customers should live in the same Audience or separate Audiences during scoping.
Sales Journey
Tag/Label
Mailchimp
Tag
1:1Sales Journey tags export as flat lists per contact and map directly to Mailchimp Tags. Tag taxonomy is preserved as-is; Mailchimp applies tags as single-level labels without hierarchy. If the Sales Journey taxonomy includes nested tag groups, we flatten them to a flat tag list and note the original grouping in the scoping document for the customer's admin to restructure in Mailchimp if needed.
Sales Journey
Activity/Engagement
Mailchimp
Not Migrated
lossySales Journey activity records (calls, emails, meetings, tasks) have no Mailchimp equivalent. Mailchimp tracks email campaign engagement (opens, clicks, bounces, unsubscribes) but does not maintain a sales activity timeline. We do not migrate activity history. The scoping report notes the volume of activity records that will not transfer so the customer can assess impact.
Sales Journey
Custom Fields
Mailchimp
Merge Fields
1:1Sales Journey custom fields on Contacts map to Mailchimp Merge Fields of the appropriate type (text, number, date, dropdown). Mailchimp supports up to 40 merge fields per Audience. If the customer has more than 40 custom fields, we prioritize the fields actively used in segmentation or reporting and flag the remainder for manual entry or a secondary tagging strategy.
Sales Journey
Owner/User
Mailchimp
Not Migrated
lossySales Journey owner assignment does not map to Mailchimp. Mailchimp does not have a user-assignment model for contacts. Owner information is dropped during migration. If the customer needs to track rep-level attribution for marketing purposes, we recommend creating a rep tag or merge field and populating it manually post-migration based on Sales Journey records.

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.
Sales Journey gotchas
Sparse platform documentation limits migration discovery
Limited customization creates rigid data structures
Engagement and activity data may not survive transit intact
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 data export
We audit the Sales Journey instance for contact volume, company associations, tags, custom fields, and any engagement or activity data. Because Sales Journey has no published API documentation, we request a live data export from the platform UI during discovery. If the export is incomplete or unavailable, we escalate to the customer so they can request data directly from Sales Journey support before migration begins. We also assess the Mailchimp destination account for existing audiences, merge fields, and tag taxonomy.
Merge field and tag mapping design
We design the Mailchimp merge field schema based on the Sales Journey data audit. Company name, industry, size, and any lead status or score fields map to named Merge Fields. Tags from Sales Journey map to Mailchimp Tags. If the customer has more than 40 custom fields, we prioritize the fields used in segmentation and flag the remainder. We design the mapping in a sandbox Mailchimp audience or a staging import for validation before the full migration runs.
Contact export and data quality check
We extract all Sales Journey contacts with their associated fields, company associations, and tags. Records with missing or invalid email addresses are flagged in a separate reconciliation queue for customer review. Records with duplicate email addresses are flagged with the source records identified so the customer can decide which record to prioritize. We do not automatically de-dupe; that decision requires customer input based on business context.
Audience import and merge field population
We import contacts into the target Mailchimp Audience using the Mailchimp API with batch chunking and exponential backoff on rate limit responses. Merge fields populate during import. Tags apply per record based on the tag mapping table. We run a row-count reconciliation comparing the source export row count against the Mailchimp audience member count to confirm completeness. Any discrepancy triggers a second extraction and re-run.
Gap documentation and rebuild handoff
We deliver a written migration report documenting what was migrated, what was not migrated, and why. This includes the deal and pipeline gap inventory, activity history gap inventory, and any custom fields that could not be mapped due to Mailchimp's 40-merge-field limit. The report includes a Customer Journey rebuild guide: a written inventory of any Sales Journey workflows or automations with their trigger, conditions, and actions mapped to recommended Mailchimp Customer Journey equivalents. The customer's admin rebuilds Customer Journeys post-migration; that work is outside the migration scope.
