Overview
The Real Estate Platform (REP) is a cloud-based CRM built for global real estate brokerages, handling leads, contacts, companies, deals, listings, and marketing campaigns across multi-lingual, multi-currency configurations. REP offers per-feature pricing and integrates primarily with Google Calendar, with limited third-party extension options that prompt teams to seek dedicated tools. Mailchimp is an email marketing platform organized around Audiences containing Subscribers, with Merge Fields replacing CRM custom properties and Tags enabling segmentation. The migration carries REP contacts into Mailchimp Subscribers using email as the unique identifier, maps REP custom contact properties to Mailchimp Merge Fields with type-aware conversion, and converts REP lists or segments into Mailchimp Tags or audience groups. The key technical decisions involve Mailchimp's Merge Field type constraints (text, number, date, address, phone, currency only), its email-uniqueness enforcement (duplicate emails collapse to one subscriber), and the absence of any deal, listing, or agent objects. FlitStack sequences the migration so Mailchimp merge field definitions are created before contacts land, ensuring no records arrive with unmapped properties. We preserve REP owner email assignments as a merge field for attribution. Workflows, sequences, and automation logic do not migrate — they require manual rebuild in Mailchimp's automation builder, and we export REP workflow definitions as a rebuild reference. Data volume, custom property count, and tag complexity drive the pricing range.

Object mapping
Each row shows how a The Real Estate Platform (REP) 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.
The Real Estate Platform (REP)
Contact
Mailchimp
Subscriber
1:1REP contacts migrate to Mailchimp subscribers by email as the unique key. Every REP contact property becomes a Mailchimp merge field or tag. Multiple REP contacts with the same email collapse to one subscriber — we surface this before migration and let you choose the primary record.
The Real Estate Platform (REP)
Lead
Mailchimp
Subscriber
1:1REP leads map directly to Mailchimp subscribers. REP lead status and lifecycle stage become merge fields since Mailchimp has no native lead-lifecycle concept. Lead source, lead score, and any custom lead properties migrate as merge fields. The migration treats leads identically to contacts — both become subscribers in Mailchimp with their REP attributes preserved in custom merge fields.
The Real Estate Platform (REP)
Company
Mailchimp
Merge Field (COMPANY)
1:1REP company associations do not create a separate object in Mailchimp. Instead, the primary company name migrates as a COMPANY merge field on the subscriber. If REP contacts link to multiple companies, additional company names are appended to the merge field or stored as a comma-separated list.
The Real Estate Platform (REP)
Deal
Mailchimp
No Equivalent
1:1Mailchimp has no deal or pipeline objects. Deal name, amount, stage, close date, and owner do not map to any Mailchimp construct. We preserve deal data as a JSON-encoded string in a custom merge field for reference, but deal management requires a separate CRM post-migration.
The Real Estate Platform (REP)
Listing
Mailchimp
No Equivalent
1:1REP listing objects (property address, status, price, MLS ID, listing agent) have no Mailchimp equivalent. Mailchimp's contact-centric model cannot represent real estate inventory. Listing data is excluded from the migration and must be managed in a dedicated property management or MLS tool.
The Real Estate Platform (REP)
Agent
Mailchimp
No Equivalent
1:1REP agent profiles with role-based access and productivity metrics do not translate to Mailchimp. Mailchimp users are platform administrators only. Agent attribution on contacts migrates as a custom merge field so you can see which REP agent managed each contact.
The Real Estate Platform (REP)
REP List / Segment
Mailchimp
Mailchimp Tag or Audience Group
1:1REP named lists and segments map to Mailchimp tags applied to subscribers. If REP uses audience-level lists (separate contact pools), we create multiple Mailchimp audiences and map each REP list to its corresponding audience. Segments requiring compound filter logic become Mailchimp tags plus Saved Segments for rebuild reference.
The Real Estate Platform (REP)
REP Tag
Mailchimp
Mailchimp Tag
1:1REP tags with categorical values (e.g., property_type: condo, source: website) map directly to Mailchimp tags. Tag names are preserved verbatim. Multi-value tags (a contact may have multiple tag values) are handled by applying each value as a separate Mailchimp tag on the same subscriber.
The Real Estate Platform (REP)
Custom Property (checkbox, multi-select, URL)
Mailchimp
Merge Field (text-encoded)
1:1Mailchimp merge fields do not support checkbox, multi-select, or URL types natively. We convert checkbox to text (true/false), multi-select to comma-separated text, and URL to text. If a REP property uses a multi-select with many possible values, we discuss with you whether to use tags or a text merge field.
The Real Estate Platform (REP)
REP Campaign History
Mailchimp
Campaign Name Reference
1:1REP email campaign subject lines and send dates are preserved as a custom merge field for historical reference. The actual campaign content and performance metrics do not migrate — Mailchimp's campaign reporting starts from go-live. This preserves the audit trail of what was sent from REP without transferring engagement data that would be meaningless in a new platform.
The Real Estate Platform (REP)
Owner / Agent Attribution
Mailchimp
Merge Field (OWNER_EMAIL)
1:1Mailchimp has no owner model. REP owner email assignments migrate as an OWNER_EMAIL merge field on each subscriber so you can attribute contacts to the REP agent who managed them. This is informational only — Mailchimp's user management is separate.
The Real Estate Platform (REP)
Activity (calls, notes, meetings)
Mailchimp
No Equivalent
1:1REP activity history (logged calls, notes, meeting records) has no Mailchimp equivalent. Mailchimp tracks opens and clicks on campaigns sent through its platform, but historical REP activity records are not transferred. We recommend exporting REP activity logs as a CSV for offline reference.

Migration approach
Audit REP contact schema and run pre-migration duplicate-email check
We connect to REP using read-only API credentials and pull a complete export of contacts, leads, custom properties, lists, segments, and tags. We run a duplicate-email audit to identify contacts sharing the same address — a critical step since Mailchimp enforces email uniqueness. We also inventory all REP custom properties, classify their data types, and flag any that exceed Mailchimp's merge field type constraints. This audit produces a migration plan document with the full field mapping table and any conflicts that need your decision before migration.
Create Mailchimp merge field definitions before contacts land
We create all required Mailchimp merge fields in your audience before any subscriber records are migrated. This includes standard fields (FNAME, LNAME, PHONE, COMPANY, etc.) and custom fields (LIFECYCLE_STAGE, LEAD_STATUS, OWNER_EMAIL, DEAL_REFERENCE, etc.) with appropriate type assignments. If the field count exceeds Mailchimp's 40-field limit, we implement the consolidation strategy agreed upon in Step 1 and document it in the field mapping reference. Merge fields are created via Mailchimp's API with validation to confirm each field is correctly typed.
Resolve owner emails and map REP tags to Mailchimp tags
We match REP owner email addresses against Mailchimp subscriber records to resolve attribution. For REP tags, we create corresponding Mailchimp tags and apply them to migrated subscribers. If REP uses separate lists (distinct contact pools rather than tags), we create multiple Mailchimp audiences and map each REP list to its audience. For REP segments, we build the equivalent Mailchimp Saved Segments using the segment translation document. This step runs in parallel with merge field creation to minimize total migration time.
Run sample migration with field-level diff before full commit
A representative slice of contacts — typically 100–500 records spanning different REP lists, lifecycle stages, and contacts with the most custom properties — migrates first. We generate a field-level diff comparing each REP field value against the corresponding Mailchimp merge field value. You verify the mapping for lifecycle stages, owner attribution, multi-select consolidation, and tag application. Any mapping errors are corrected before the full migration runs. This sample also validates that Mailchimp's 40-field limit is not exceeded in the production audience.
Execute full migration with delta-pickup and rollback availability
Full REP contact migration runs against your Mailchimp audience using the validated field mapping. A delta-pickup window of 24–48 hours captures any REP contacts modified or created during the cutover period. Our audit log records every operation (create, update, skip, collapse) for reconciliation. If post-migration validation finds unexpected issues, one-click rollback reverts the Mailchimp audience to its pre-migration state so you can correct the mapping and re-run without data loss.
