Overview
Moving from Xapsys CRM to Mailchimp is a scope reduction, not a lateral platform move. Xapsys is a full CRM with Companies, Contacts, Opportunities, custom entities, document management, and workflow automation. Mailchimp is an email marketing platform built around Audiences, Contacts, Tags, Segments, Campaigns, and Automations. We migrate what maps cleanly — Contacts into Subscribers, tag classifications into Mailchimp tags, and custom field values into merge fields — and we flag what has no Mailchimp equivalent: Opportunities, Documents, Custom Entities, and Xapsys Workflows. We do not migrate workflows, automations, or sequences as code; we produce a written inventory of each active rule so your team rebuilds them in Mailchimp's Automation builder post-migration. The migration sequence loads Contacts first, resolves company affiliations through the Tags system, and validates opt-in status before the final audience sync.
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 Xapsys 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.
Xapsys CRM
Contact
Mailchimp
Subscriber/Contact
1:1Xapsys Contacts migrate to Mailchimp Contacts within a designated Audience. The Contact's email address becomes the subscriber key and the primary dedupe identifier. First name, last name, phone, and address fields map to Mailchimp standard merge fields (FNAME, LNAME, PHONE, ADDRESS). Opt-in status is set based on Xapsys communication preferences field; contacts with no explicit opt-in preference are flagged for confirmation email before the audience goes live.
Xapsys CRM
Company
Mailchimp
Audience or Tag
1:manyXapsys Companies do not have a direct Mailchimp equivalent because Mailchimp does not have an Account/Company object. We handle the affiliation in one of two ways during scoping: for organizations that want to preserve company context, we create a Mailchimp Tag named after the Company and apply it to all Contacts belonging to that Company. For organizations prioritizing a flat contact list, we drop the company linkage and document it as a post-migration data enrichment task.
Xapsys CRM
Tag / Classification
Mailchimp
Tag
1:1Xapsys classification tags on Contacts map directly to Mailchimp Tags. Each Xapsys tag value becomes a Tag in Mailchimp, and we apply it to all Contacts with that classification. If a Contact has multiple Xapsys tags, it receives multiple Mailchimp Tags. Tags are used for segmentation in Mailchimp so the mapping preserves the segmentation logic that the team built in Xapsys.
Xapsys CRM
Custom Fields
Mailchimp
Merge Fields
lossyXapsys custom fields on Contact records (beyond the standard name/email/phone/address set) translate to Mailchimp Merge Fields of the equivalent type: text fields to TEXT merge fields, date fields to DATE merge fields, numeric fields to NUMBER merge fields, and picklist fields to either RADIO or dropdown merge fields. We extract the custom field schema from the Xapsys instance during discovery and provision merge fields in the target Audience before import.
Xapsys CRM
Custom Entities
Mailchimp
Tags, Notes, or External Reference
1:1Xapsys custom entities vary by deployment and have no direct Mailchimp equivalent. During scoping we extract the custom entity schema, identify which entities are actively used versus historical, and decide per-entity: tag the associated Contact with the entity name, store the entity value as a text merge field, or flag it as requiring a post-migration external reference document. No custom entity migrates as a first-class object.
Xapsys CRM
Opportunity
Mailchimp
Not migratable
lossyXapsys Opportunities (deals with stages, values, and close dates) have no Mailchimp equivalent. Mailchimp does not track pipeline stages, deal values, or sales forecasting. We flag the total count and stage distribution of Opportunities during discovery, export them as a CSV for the customer's admin to load into a spreadsheet or alternative CRM, and document the Opportunity count and field set in the migration inventory report.
Xapsys CRM
Document
Mailchimp
Not migratable
lossyXapsys Documents linked to Companies and Opportunities cannot migrate to Mailchimp. Mailchimp supports file attachments to campaigns and emails but has no document library or attachment-to-contact association. We export the document metadata (filename, linked Contact, linked Company, upload date) as a CSV that the customer's admin uses to repoint document storage to SharePoint, Google Drive, or a dedicated DMS post-migration.
Xapsys CRM
Workflow
Mailchimp
Not migratable
lossyXapsys workflow rules — automated triggers, stage-change actions, and email sequences — do not export via any documented mechanism. Mailchimp Automation has a different trigger-and-customer-journey model that cannot import Xapsys workflow logic. We catalog every active Xapsys Workflow during discovery with its trigger, conditions, actions, and target audience, and deliver a written automation inventory so the customer's team rebuilds the revenue-critical automations in Mailchimp's Automation builder after go-live.

Migration approach
Schema discovery and custom entity extraction
We connect to the Xapsys instance using read-only credentials (obtained from the customer's admin) and extract the full schema: standard objects (Contacts, Companies, Opportunities), custom entity definitions, tag/classification field definitions, workflow list, and document metadata. We produce a schema inventory document that lists every field, its type, and its usage count. This phase confirms that Xapsys API export is available and identifies any objects that require manual CSV extraction rather than API pull.
Audience design and merge field provisioning
We create the target Mailchimp Audience and provision merge fields matching the Xapsys custom field schema extracted in discovery. We decide with the customer whether Xapsys Companies map to Tags (preserving affiliation) or are dropped (flat contact list). We configure tag names for Xapsys classification values and set up the confirmation email flow for any contacts without an explicit opt-in flag.
Data cleansing and deduplication
We run a data quality pass on the Xapsys export before import: email deduplication (mailchimp subscriber key is email address), address normalization, phone format standardization, and identification of contacts with no email address (these cannot migrate and are flagged in the inventory). We resolve Xapsys Company affiliations to tag application during this phase.
Pilot import of 50 contacts
We import a sample of 50 Contacts from the Xapsys export into the Mailchimp Audience, verify that merge fields populate correctly, tags apply as expected, and the confirmation email fires for unconfirmed contacts. The customer's team spot-checks the sample in Mailchimp before we proceed to full import. Any field mapping corrections happen at this stage.
Full contact migration and reconciliation
We run the full Contact import using Mailchimp's bulk API with batching and rate-limit handling. We reconcile row counts: Contacts exported from Xapsys versus Subscribers created in Mailchimp. Any rejected records (due to invalid email format or API errors) are logged and resolved in a second-pass import. We then apply tags corresponding to Xapsys Company affiliations and classification values.
Cutover, validation, and automation inventory delivery
We freeze writes to Xapsys during cutover and run a delta migration for any contacts modified during the migration window. We deliver the written inventory of Opportunities, Documents, Custom Entities, and Workflows with field counts and recommended handling (archive, CSV export, or rebuild). We support a 72-hour hypercare window for reconciliation issues raised by the customer's team.
