Overview
PropertySimple stores real estate prospect data as contacts with custom fields (agent assignment, property interest, ZIP code interest) and an internal CRM workflow layer. Mailchimp's data model centers on an audience — each subscriber has one contact record with standard fields (email, first name, last name) plus custom merge fields. PropertySimple's contact properties, tags, and deal-stage associations need to be translated into Mailchimp merge fields, tags, and group segments. We map the full contact record including email addresses, phone numbers, agent assignments, and any custom property fields to Mailchimp merge fields. Activity history (emails sent from PropertySimple sequences) migrates as historical campaign data if available via API, or surfaces as a tag-based reference record for your team to rebuild sequences in Mailchimp's automation builder. Workflows, automations, and social-media-triggered sequences do not transfer — they require manual rebuild in Mailchimp. We extract via PropertySimple's API, transform to Mailchimp's merge-field schema, and load into your Mailchimp audience. A 24–48 hour delta-pickup window captures any new leads created during the cutover window.
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 PropertySimple 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.
PropertySimple
Contact
Mailchimp
Subscriber (Audience Member)
1:1PropertySimple contacts map directly to Mailchimp subscribers in your primary audience. Each contact's email address becomes the subscriber identifier. First name, last name, and phone migrate as merge fields. Owner and agent assignment fields store as custom merge fields since Mailchimp has no native owner model.
PropertySimple
Lead
Mailchimp
Subscriber (same Audience)
1:1PropertySimple leads merge into the same Mailchimp audience as contacts. There is no separate lead object in Mailchimp — all prospects live in one subscriber list. Lead status or source tracking (inquiry form, open house, referral) stores as a merge field or tag so segmentation remains possible.
PropertySimple
Company
Mailchimp
Merge Field (Organization Name)
1:1PropertySimple company records (brokerage or agency names associated with contacts) flatten into the contact record as an ORGANIZATION merge field. Mailchimp has no native company object — company context lives as a text field on each subscriber record. Primary company assignment maps directly; multi-company associations collapse to one value per contact.
PropertySimple
Deal / Listing Interest
Mailchimp
Tag + Merge Field
1:1PropertySimple deal records and listing interest signals map to Mailchimp tags (e.g., 'Buyer', 'Seller', 'Investor') and a property-interest merge field capturing the ZIP code or listing ID. Tags enable segment-based email sends while merge fields preserve the specific property context for personalization.
PropertySimple
Agent Assignment
Mailchimp
Custom Merge Field (AgentName)
1:1PropertySimple's owner/agent assignment field has no direct Mailchimp equivalent. We create an AGENT_NAME merge field on the audience so each subscriber record retains which agent owns the relationship. If your team uses Mailchimp's multi-user accounts, agent names can alternatively map to Mailchimp user names for permission-based campaign assignment.
PropertySimple
Contact Tag / Category
Mailchimp
Tag
1:1PropertySimple's category labels (e.g., 'Hot Lead', 'Past Client', 'Sphere of Influence') map 1:1 to Mailchimp tags. Tags copy exactly so your existing audience segments based on contact type translate directly into Mailchimp segment filters. Tags are additive — a contact can carry multiple tags from PropertySimple.
PropertySimple
Property / Listing Association
Mailchimp
Merge Field (PropertyZIP or ListingRef)
1:1PropertySimple's listing and property associations (ZIP code interest, listing ID, property type preference) require a custom merge field in Mailchimp since the platform has no native real estate listing object. We create PROPERTYZIP and LISTINGREF merge fields capturing the source data for use in email personalization tokens.
PropertySimple
Activity History (Emails Sent)
Mailchimp
Historical Tag Reference
1:1PropertySimple sequence and email activity (opens, clicks, sends) has no clean Mailchimp equivalent because the activity originates in PropertySimple's own sequence builder. We create a tag for each active sequence (e.g., 'PS-Nurture-Sequence-Active') as a reference indicator. The full activity log does not transfer; it must be reviewed from PropertySimple reports before the migration cutover date.
PropertySimple
Custom Property Fields
Mailchimp
Merge Fields
1:1Any PropertySimple custom contact fields (mortgage status, move timeline, bedroom range preference) create as Mailchimp merge fields. Mailchimp supports text, number, date, address, phone, and URL merge field types. We match field type to Mailchimp's supported types — long text areas require a workaround since Mailchimp merge fields cap at 255 characters.
PropertySimple
Social Media Ad Data
Mailchimp
Not Migrated
1:1PropertySimple's social media ad performance data (impressions, clicks, ad spend per listing) lives in PropertySimple's native reporting and does not have a migration path to Mailchimp. If ad campaign context matters for your email personalization, you can export the ad performance CSV separately and manually append relevant signals as merge field values before import.
PropertySimple
Workflow / Automation Definitions
Mailchimp
Not Migrated
1:1PropertySimple workflows (AI follow-up triggers, lead assignment rules, social post schedules) do not transfer to Mailchimp. They require manual rebuild in Mailchimp's Customer Journeys builder. We provide a workflow audit export listing each active PropertySimple sequence with its trigger conditions, step count, and message content so your team can reconstruct the logic in Mailchimp.
PropertySimple
Unsubscribe / Preference Data
Mailchimp
Suppression Import
1:1PropertySimple unsubscribes and suppressed contacts export as a suppression list that gets imported into Mailchimp before the main audience import. This prevents accidentally emailing people who opted out in PropertySimple. FlitStack handles this as a pre-import step so your Mailchimp sender reputation is protected from day one.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
PropertySimple gotchas
No documented public API for automated data extraction
ZIP Code exclusivity settings have no standard CRM equivalent
AI-generated content assets are platform-locked
Pricing tiers are tied to platform features, not data limits
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Audit PropertySimple data export and define Mailchimp audience schema
We connect to PropertySimple via API and export a full contact and lead inventory, including all custom property fields, tags, lifecycle stages, and agent assignments. We review the field inventory against Mailchimp's merge field limits and types, flag any fields exceeding 255 characters, identify multi-value fields that need splitting, and confirm the suppression list export for pre-import into Mailchimp. You confirm which PropertySimple lists map to which Mailchimp audience(s) and whether consolidation is preferred.
Build merge field schema and tagging strategy in Mailchimp
FlitStack creates all required merge fields in your Mailchimp audience: AGENT_NAME, PROPERTYZIP, LISTINGREF, LIFECYCLE, DEALSTAGE, MORTGAGE, MOVETIME, BEDROOM, and any other PropertySimple custom fields. We also define the tag taxonomy matching PropertySimple contact types (Buyer, Seller, Investor, Sphere). Tags are applied during import; merge fields are populated from PropertySimple field values. Suppression list imports run before the main audience import to protect sender reputation.
Run sample migration with field-level validation
A representative sample of 200–500 PropertySimple contacts migrates into your Mailchimp audience. We generate a field-level validation report showing each merge field's populated rate, tag application accuracy, and any records that failed due to missing email addresses or malformed data. You review the sample in Mailchimp to confirm personalization tokens display correctly and segmentation preview makes sense before the full run commits.
Execute full migration with delta-pickup window
The full contact and lead inventory migrates into Mailchimp with a 24–48 hour delta-pickup window open. Any new PropertySimple contacts created or modified during the migration run are captured in the delta pass so your Mailchimp audience reflects PropertySimple's final state at cutover. Audit logs record every operation. One-click rollback is available if reconciliation against the source inventory reveals discrepancies.
Deliver workflow audit export for manual rebuild in Mailchimp
We export a structured reference document listing every active PropertySimple automation and sequence: trigger conditions, step count, message subject lines, and send-time logic. This becomes the blueprint for rebuilding in Mailchimp's Customer Journeys builder. We do not migrate automations automatically, but the export gives your team a complete rebuild checklist with source-side context preserved. Post-migration support includes a 30-minute review call to validate merge field population and answer segmentation questions.
