Overview
Migrating from Anthill CRM to Mailchimp is a directional shift from a full-process CRM to an email marketing platform. Anthill stores Enquiries, Customers, Activities, Workflow streams, and custom dashboard configurations that have no direct Mailchimp analog. We extract contact records with their email, phone, and address fields and map them to Mailchimp Contacts within the target Audience. We preserve subscription status, tags, and any email engagement history as merge-field values. We do not migrate Deals, workflow states, automations, dashboards, or user team assignments because Mailchimp's data model does not support these objects. We deliver a written inventory of every Anthill workflow, automation trigger, and dashboard that requires rebuild in Mailchimp's automation and design tools post-migration.
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 Anthill 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.
Anthill CRM
Customer
Mailchimp
Contact (within Audience)
1:1Anthill Customer records map to Mailchimp Contacts within the target Audience. We extract first_name, last_name, email, phone, and address fields and map them to Mailchimp's standard contact fields. Email address serves as the dedupe key. Any Customer without a valid email address is flagged for the customer to supply or archive. Customer status fields from Anthill map to Mailchimp Tags for segmentation in post-migration cleanup.
Anthill CRM
Company
Mailchimp
Tag or Merge Field
lossyAnthill Company records do not have a direct Mailchimp equivalent because Mailchimp has no native company-account object. We map Company name to a merge field (COMPANY or COMPANY_NAME) applied to each Contact. If the customer requires company-level segmentation, we create Tags prefixed with the company name and apply them to all Contacts belonging to that company during the import run. This is a manual design decision made during scoping.
Anthill CRM
Enquiry
Mailchimp
Tag (status-based)
lossyAnthill Enquiry records represent intake or inbound leads at the top of the workflow stream. Because Mailchimp has no pipeline or deal object, we carry Enquiry status as Tags on the corresponding Contact record. Each workflow stage name becomes a Tag value, preserving which stage the original Enquiry occupied. The customer decides during scoping whether to carry full stage history as multiple tags or retain only the most recent stage.
Anthill CRM
Activity (email and SMS engagements)
Mailchimp
Merge Field or Tag
1:1Anthill email and SMS activities tied to Customer records migrate as tagged metadata on the Mailchimp Contact. We extract the most recent engagement date, total engagement count, and preferred channel (email vs SMS) and write these as merge field values. Full activity timestamps and content do not migrate as records because Mailchimp's contact model does not support a native activity timeline. We document each engagement record in a CSV inventory for the customer to reference if needed.
Anthill CRM
User
Mailchimp
Mailchimp User (access tier)
1:1Anthill Users assigned to Sales, Admin, and Support teams map to Mailchimp Users with appropriate access tiers (Manager, Admin, Author, Viewer). We match by email. Anthill's team-level role restrictions have no Mailchimp equivalent; team-level permission scoping is a configuration the customer sets in Mailchimp's audience permissions after migration. Users without a Mailchimp account are reconciled before production migration.
Anthill CRM
Workflow
Mailchimp
Customer Journey (documented for rebuild)
1:1Anthill Workflows define customer interaction processes with team-level task assignments and state-based triggers. Mailchimp's Customer Journeys use a different trigger-and-delay model with no concept of team task allocation. We do not migrate Workflows as code. We audit every active Anthill Workflow, document its trigger conditions, stage sequence, and assigned actions, and deliver a written Workflow Inventory specifying which Customer Journey steps the customer's admin should configure in Mailchimp to replicate the customer communication logic.
Anthill CRM
Automation
Mailchimp
Customer Journey (documented for rebuild)
1:1Anthill Automations trigger personalised email and SMS sequences based on workflow state transitions. Mailchimp Customer Journeys support comparable trigger-based automation but use a different builder and action model. We do not migrate Automations as code. We document every active Anthill Automation with its trigger, conditions, sequence order, and delay rules, and deliver this as a rebuild guide for the customer's Mailchimp admin.
Anthill CRM
Dashboard
Mailchimp
No equivalent (documented for manual rebuild)
1:1Anthill live role-based dashboards are configuration files stored in the platform's visualisation engine and are not accessible via API. Mailchimp does not offer a custom dashboard builder. We cannot export dashboard configurations. We document every Anthill dashboard's layout, metrics, filters, and data sources from the live system during scoping and deliver this as a rebuild specification for the customer's admin to reference when building reports in Mailchimp's analytics section or exporting to an external BI tool.

Migration approach
Discovery and scoping
We audit the Anthill CRM instance via the JSON API, extracting Customer records, Company records, Enquiry records, Activity counts, active Workflow definitions, active Automations, and dashboard configurations. We pull a field inventory by introspecting actual API responses to capture any custom properties. We review the Mailchimp target Audience and access tier setup. The discovery output is a written scope document specifying which objects migrate, which are documented for rebuild, which fields map directly, and which require transformation or tagging decisions from the customer.
Data cleansing and deduplication
We run contact records through a validation pass: email format checks, duplicate detection (matching on email address), and identification of records missing required fields (email, first name). Duplicate records are flagged for the customer to decide which to retain. Records with invalid or missing email addresses are held in a quarantine list. We also normalise phone number formats and address fields to Mailchimp's expected structure before the import run.
Schema mapping and tagging strategy
We design the Mailchimp tagging strategy based on the Anthill data model. Company names become Tags or merge field values on each Contact. Workflow stage states become Tags on the Contact record. Any Anthill custom fields are mapped to Mailchimp merge fields where type-compatible, or flagged as Tags for manual segmentation. This mapping is documented and signed off by the customer before any data is written to Mailchimp.
Sandbox import and validation
We run a trial import into a Mailchimp test Audience using a representative data sample (typically 10-20% of total records). We validate contact field mapping, tag application, merge field population, and subscription status transfer. We reconcile row counts between the Anthill source and the Mailchimp destination. Any mapping corrections are applied before the production import run begins.
Production import and reconciliation
We run the full production import into the target Mailchimp Audience in batches. Each batch emits a reconciliation report comparing source record count to destination contact count and flagging any records that failed to import. Failed records are retried in a corrective pass. We validate subscription status (opted-in, opted-out) against the Anthill source preferences and ensure no unintended status changes occurred during import.
Deliverables handoff and Workflow rebuild guide
We deliver the final migration report including record counts by object, import success rate, and any records held in quarantine with reasons. We deliver the Workflow Inventory and Automation Inventory documents specifying every Anthill workflow and automation requiring rebuild in Mailchimp Customer Journeys. We deliver the Dashboard Rebuild Specification documenting every Anthill dashboard's layout and metrics. We do not rebuild workflows, automations, or dashboards as these fall outside migration scope. We offer a one-week post-migration support window to address import reconciliation issues raised during the first send.
