Overview
Empire Suite stores contacts, companies, deals, and custom properties in a relational CRM schema. Mailchimp organizes data around a single Audience model with subscriber records, merge fields, tags, and campaign-level engagement tracking. The migration maps Empire Suite contacts to Mailchimp subscribers, translating company associations and custom contact properties into Mailchimp merge fields and tags. Deal and pipeline data has no direct Mailchimp equivalent and is exported as a reference CSV for manual review. Workflows and automation sequences in Empire Suite do not migrate — they must be rebuilt using Mailchimp's automation tools. FlitStack AI accesses Empire Suite via its API or bulk export, normalizes field names, de-duplicates by email address, and imports into Mailchimp in a sequenced run with a 24–48 hour delta pickup window capturing any new subscribers added during cutover. During the migration, FlitStack AI validates each record against Mailchimp's schema, maps each Empire Suite custom property to the appropriate merge field or tag, and flags any records that exceed Mailchimp's merge field limits for plan upgrade or tag conversion. After the initial import, a delta window captures new or updated contacts in Empire Suite, ensuring a continuous audience sync. Comprehensive audit logs record every record imported, any validation failures, and the actions taken. If unexpected divergence occurs, a one-click rollback reverts the Mailchimp audience to its pre-migration state, allowing your team to resolve data issues before finalizing the cutover.
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 Empire SUITE 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.
Empire SUITE
Contact
Mailchimp
Subscriber (Audience Member)
1:1Empire Suite contact records map 1:1 to Mailchimp audience members by email address. First name, last name, email, phone, job title, and address fields translate to Mailchimp's standard merge fields (FNAME, LNAME, EMAIL, PHONE, JOBTITLE, ADDRESS). Records without an email address are flagged for manual review before import.
Empire SUITE
Company
Mailchimp
Merge Field + Tag on Subscriber
1:1Empire Suite company name maps to a COMPANY merge field on the Mailchimp subscriber. Company industry, annual revenue, and employee count migrate as additional merge fields. If a contact has multiple associated companies, the primary company maps to the merge field and secondary companies are preserved as tags for segmentation reference.
Empire SUITE
Deal / Opportunity
Mailchimp
Reference CSV Export
1:1Empire Suite deal records — with pipeline stage, amount, close date, and owner — have no direct Mailchimp equivalent. We export these as a structured CSV so your team can import them into a separate spreadsheet or reporting tool. Deals do not become Mailchimp campaigns or automations.
Empire SUITE
Contact Custom Fields
Mailchimp
Merge Fields
1:1Every Empire Suite custom property on a contact becomes a Mailchimp merge field. Mailchimp's free plan allows 30 merge fields; Mailchimp Premium raises this to 80. If your Empire Suite contact record has more than 30 custom properties, we recommend a Premium plan or collapsing low-value fields into tags before migration.
Empire SUITE
Company Custom Fields
Mailchimp
Merge Fields
1:1Company-level custom properties (e.g., contract tier, account manager, renewal date) map to merge fields on the associated subscriber records. These add to the merge-field count alongside contact custom fields, so plan accordingly when choosing a Mailchimp plan tier. This ensures you stay within merge field limits and avoid import errors.
Empire SUITE
Contact Tags / Labels
Mailchimp
Mailchimp Tags
1:1Empire Suite contact tags and association labels (e.g., 'VIP', 'Decision Maker', 'Referral Partner') translate directly to Mailchimp tags on the subscriber record. Tags preserve segmentation logic built in Empire Suite and can be used immediately in Mailchimp segments and automation triggers.
Empire SUITE
Engagement Activity (Emails, Calls, Meetings)
Mailchimp
Historical Notes Field
1:1Empire Suite activity history (logged calls, emails, meetings, notes) is preserved as a structured note attached to the subscriber record in Mailchimp. This maintains a reference trail, but Mailchimp's native open/click tracking begins fresh after the migration date — historical engagement metrics do not carry over.
Empire SUITE
User / Owner
Mailchimp
No Equivalent
1:1Empire Suite owner assignments (sales rep, account manager) do not map to Mailchimp's shared-audience model. Mailchimp does not assign record ownership to individual users. If owner attribution matters for reporting, we can add an OWNER merge field so campaigns can be tagged by rep for manual attribution.
Empire SUITE
Pipeline
Mailchimp
No Equivalent
1:1Empire Suite deal pipelines and stage configurations have no Mailchimp equivalent. Pipeline definitions are exported as a reference document. Stage-based routing or deal-triggered automations must be rebuilt in Mailchimp using automation triggers based on merge-field values or tag changes. This ensures that workflow continuity is maintained after the migration.
Empire SUITE
Attachment / File
Mailchimp
External Storage Reference
1:1Files attached to Empire Suite contacts or companies are not imported into Mailchimp. We document the original file URLs in a reference CSV. If these files need to be accessible to subscribers, they must be hosted externally and linked from within Mailchimp email templates.

Migration approach
Export and audit Empire Suite data
FlitStack AI connects to Empire Suite via API or bulk export to retrieve all contact records, company records, custom field definitions, and contact tags. We run a data-quality audit that identifies duplicate email addresses, missing emails, unsubscribed status, custom field counts per record, and records exceeding Mailchimp's 30-merge-field free-plan limit. The audit output is a field-mapping spreadsheet reviewed by your team before migration begins.
Configure Mailchimp audience and merge fields
Before importing, we create the Mailchimp audience and pre-define all merge fields needed for the migration. Standard fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS, COMPANY) are created from Mailchimp's built-in set. Custom merge fields are created for each Empire Suite custom property that will migrate. If the custom field count exceeds Mailchimp's plan limit, we surface this and recommend upgrading or converting overflow fields to tags before the import run.
Suppress unsubscribed and bounced contacts
Empire Suite contacts with an unsubscribed or bounced email status are exported separately and imported into Mailchimp as a suppression list rather than active subscribers. This prevents re-engagement emails from being sent to contacts who previously opted out and protects your Mailchimp sending reputation from the outset. Only contacts with an active, opted-in status in Empire Suite are queued for the subscriber import.
Run sample migration with field-level verification
A representative slice of 100–500 contacts migrates first, spanning contacts with and without company associations, contacts with the highest custom field counts, and tagged contacts. We generate a field-level diff showing every Empire Suite field value alongside its Mailchimp merge field result so you can verify company mapping, tag assignment, and merge field population before the full run commits. Any discrepancies are flagged for your review before final import.
Execute full migration with delta pickup window
The full contact and company migration runs against Mailchimp. A delta pickup window of 24–48 hours runs in parallel, capturing any new contacts added to Empire Suite during the cutover period. Audit logs record every imported subscriber and any records that failed validation. One-click rollback is available if reconciliation uncovers unexpected data divergence. Post-migration, we provide a detailed summary report with import metrics and any action items for remediation.
