Overview
Inmovilla organizes real estate data around properties, contacts, and agencies — with objects for property listings, client contacts, leads, activities, and portal sync. Mailchimp is an audience-first platform that stores subscribers with standard contact fields plus custom properties, tags, and segmentation lists. The fundamental mismatch is that Inmovilla's property-centric model (with property IDs, listing statuses, and real estate portal associations) has no direct equivalent in Mailchimp, which treats every record as a subscriber in an audience. FlitStack AI resolves this by mapping Inmovilla contacts to Mailchimp subscribers, storing property references and listing status as custom fields, converting activity history into tagged notes, and preserving original timestamps. Workflows, automation sequences, email templates, and portal sync configurations do not migrate — those must be rebuilt in Mailchimp's automation builder. The migration uses Inmovilla's API export to read contacts and related data, transforms property associations into Mailchimp custom fields, and imports into your Mailchimp audience with a delta-pickup window to capture in-flight changes during 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 Inmovilla 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.
Inmovilla
Contacto (Contact)
Mailchimp
Subscriber (Mailchimp Audience)
1:1Inmovilla contacts map directly to Mailchimp subscribers within an audience. Email address is the primary key for matching. Inmovilla contacts without valid email addresses are flagged for manual review before import, as Mailchimp requires a deliverable email for every subscriber record.
Inmovilla
Empresa / Inmueble (Company / Property)
Mailchimp
Custom Fields on Subscriber
1:1Inmovilla's property associations have no native equivalent in Mailchimp. We store property reference IDs, listing status (Activo, Reservado, Vendido), and property type as custom fields on each subscriber record. This preserves the property-contact relationship without requiring a separate Property object in Mailchimp.
Inmovilla
Lead / Prospecto
Mailchimp
Subscriber with Tag
1:1Inmovilla leads migrate as Mailchimp subscribers and are tagged 'Lead' or 'Prospecto' to distinguish them from confirmed clients. This allows Mailchimp segmentation to isolate lead-stage contacts for nurture campaigns without requiring a separate audience. Additionally, tagging preserves lead source information for future analysis and re-engagement workflows.
Inmovilla
Actividad (Call, Email, Meeting, Note)
Mailchimp
Subscriber Notes + Tags
1:1Inmovilla activity history (calls, emails, meetings, notes) is reconstructed in Mailchimp using a combination of subscriber notes fields and tags for activity type. Each activity type gets its own tag (e.g., 'Activity-Call', 'Activity-Meeting') so you can filter subscribers by engagement history. Timestamps are preserved as tag metadata.
Inmovilla
Etiqueta / Segmento (Tag / Segment)
Mailchimp
Mailchimp Tag
1:1Inmovilla tags and segments map 1:1 to Mailchimp tags. Tag names are preserved exactly, and tags are applied during the initial import. Mailchimp's flat tag model means any Inmovilla tag hierarchy collapses into a simple tag list — we document the original hierarchy for your team to rebuild as groups or separate tags if needed.
Inmovilla
Usuario / Propietario (Owner)
Mailchimp
Mailchimp Merge Field + Tag
1:1Inmovilla owner assignment (the agent responsible for a contact or property) migrates as a custom merge field (OwnerName__c) on each subscriber. We also tag each subscriber with the owner's name so segmentation by agent works immediately in Mailchimp. If an owner has no matching email in your Mailchimp account, the tag still applies but no Mailchimp user is assigned.
Inmovilla
Portal sync status (Idealista, Fotocasa)
Mailchimp
No Equivalent
1:1Inmovilla's portal synchronization status for property listings (synced to Idealista, Fotocasa, etc.) has no Mailchimp equivalent. We export this as a reference note on the subscriber record but do not recreate portal sync functionality in Mailchimp, which is not a real estate platform.
Inmovilla
Custom Fields (Contacto, Inmueble)
Mailchimp
Mailchimp Custom Fields
1:1Inmovilla custom fields on contacts and properties are mapped to Mailchimp custom fields. We create the custom field in Mailchimp with the appropriate type (text, number, date, dropdown) before import. For dropdown-type custom fields, we replicate the Inmovilla pick-list values as Mailchimp options.
Inmovilla
Documento / Adjunto
Mailchimp
No Equivalent
1:1Inmovilla documents attached to contacts or properties (contracts, ID scans, property photos) do not migrate to Mailchimp. Mailchimp has no document attachment capability for subscriber records. We export a manifest of all attached files with their Inmovilla record reference so your team can re-upload them to a document storage system if needed.
Inmovilla
Workflow / Automatización
Mailchimp
No Equivalent (Must Rebuild)
1:1Inmovilla workflows (lead distribution rules, follow-up sequences, portal auto-sync) cannot migrate to Mailchimp. Mailchimp Customer Journeys use a different trigger-and-action model. We export your Inmovilla workflow definitions as a structured reference document so your team can rebuild them in Mailchimp's automation builder.

Migration approach
Audit Inmovilla data export and audience design
FlitStack AI connects to Inmovilla via API to inventory all contacts, properties, owners, tags, and custom fields. We generate a data audit report showing field-level mapping to Mailchimp's standard and custom field model. Your team decides whether to use one Mailchimp audience for all contacts or split by client type (buyers, sellers, tenants). This decision affects both the migration mapping and Mailchimp's billing calculation.
Create Mailchimp custom fields before import
We create the Mailchimp custom fields required for the migration: Property_ID__c, Property_Ref__c, Property_Type__c, Listing_Status__c, Property_Price__c, Owner_Name__c, Client_Type__c, Lead_Status__c, Agency__c, and Source_ID__c. For pick-list fields, we replicate Inmovilla's option values. This schema setup happens before any records are imported so the import process encounters no field-missing errors. We also document each custom field's purpose and expected data format, and perform a test import with a small sample to verify that values populate correctly before the full dataset loads.
Export contacts with property associations and activity history
Inmovilla's API exports contacts with their associated property references, owner assignments, and tags. Activity records (calls, emails, meetings, notes) are exported separately and linked to contacts by Inmovilla ID. We transform the property association data into the custom field values set up in step 2, and convert activity records into a tag + notes structure for Mailchimp's subscriber model. Inmovilla's internal IDs are preserved as Source_ID__c for traceability.
Run sample migration with field-level verification
A representative slice of 100-500 contacts migrates first — including contacts with property associations, activity history, and a range of tag types. We generate a field-level verification report comparing source values against the imported Mailchimp subscriber records. Your team reviews custom field values, tag application, and activity reconstruction before the full migration commits. Any mapping adjustments are applied to the migration template before the full run.
Execute full migration with delta-pickup window
The full contact database migrates into your Mailchimp audience(s). A delta-pickup window of 24-48 hours captures any Inmovilla records modified or created during the migration window — contacts added by agents during cutover are included without a separate import run. We apply all tags, custom field values, and activity-based notes during the migration. An audit log records every operation, and one-click rollback is available if reconciliation against the Inmovilla export manifest fails.
