Overview
LeadManaging organizes leads around property interests, lease applications, and prospect communications for multifamily residential teams. Mailchimp organizes subscribers around audiences, campaigns, and engagement tags with no native CRM object for property or unit data. The migration carries everything Mailchimp can accept — contacts, subscription status, phone numbers, addresses, and any LeadManaging custom property re-created as Mailchimp merge fields — and surfaces what must be rebuilt manually. LeadManaging lead stages (New, Touring, Applying, Leased, Lost) map to Mailchimp tags and segments so marketing teams can re-activate nurture sequences. Property interest data (desired unit type, move-in date, budget) migrates as custom merge fields (MERGE6, MERGE7, etc.) so campaign personalization tokens work immediately. Automations, workflows, and lease-application logic have no Mailchimp equivalent and must be rebuilt using Mailchimp's automation builder after migration. During the migration, original create timestamps and source attribution are stored as custom merge fields so historical reporting continuity is preserved. All tags that existed in LeadManaging, such as property-specific labels or demographic markers, are transferred as Mailchimp tags, maintaining segmentation logic. Because Mailchimp does not include a native lead scoring mechanism, any scoring data from LeadManaging can be stored as a numeric merge field for future reference. The delta pickup window captures changes made during the cutover window, ensuring the final Mailchimp audience reflects the latest state of your LeadManaging data.

Object mapping
Each row shows how a LeadManaging 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.
LeadManaging
Contact / Prospect
Mailchimp
Mailchimp Contact (Audience Member)
1:1LeadManaging contact records (name, email, phone, address) map directly to Mailchimp audience members. Email address serves as the primary key for deduplication. If a LeadManaging contact has no email address, it is flagged for review before migration because Mailchimp requires an email address for every subscriber.
LeadManaging
Lead Status / Stage
Mailchimp
Mailchimp Tag + Segment
1:1LeadManaging stages (New, Touring, Applying, Leased, Lost) cannot map to a native Mailchimp field because Mailchimp has no lifecycle stage object. We create a LEAD_STAGE tag per contact with the stage value, then build Mailchimp segments filtering by that tag. Segments can be used in automation triggers for stage-appropriate campaigns.
LeadManaging
Property Interest
Mailchimp
Mailchimp Merge Field (custom)
1:1LeadManaging stores desired property name, unit type preference, and rent range per lead. Mailchimp has no property object — this data migrates as custom merge fields (PROPERTY_NAME, UNIT_TYPE, RENT_MIN, RENT_MAX, MOVE_IN_DATE) created in the Mailchimp audience before contacts are imported. Merge fields must be created manually in Mailchimp or via the Mailchimp API prior to data load.
LeadManaging
Lead Source / Attribution
Mailchimp
Mailchimp Tag
1:1LeadManaging lead source fields (Website Inquiry, ILS, Referral, Walk-in, etc.) migrate as tags on each contact in Mailchimp. Tags preserve attribution data for source-based segmentation and campaign performance reporting. Multiple source tags per contact are supported. These tags can be combined with other contact attributes to build highly targeted re-engagement campaigns.
LeadManaging
Custom Property (generic)
Mailchimp
Mailchimp Merge Field
1:1Any LeadManaging custom property not covered by standard fields maps to a Mailchimp merge field. We read the LeadManaging field schema during discovery and create a corresponding merge field in Mailchimp for each custom property before importing contacts. Merge field type (text, number, date, phone) is inferred from the source data type.
LeadManaging
Notes / Activity Log
Mailchimp
Mailchimp Note
1:1LeadManaging contact notes and activity timestamps (last contacted date, last tour date, last email open) migrate as Mailchimp notes on each contact. Note content preserves the original timestamp and activity type label. Mailchimp displays notes in the contact profile sidebar for reference by the marketing team.
LeadManaging
Subscription / Opt-in Status
Mailchimp
Mailchimp Member Status
1:1LeadManaging email opt-in flag maps to Mailchimp member status: opted-in contacts become 'subscribed', explicitly opted-out contacts become 'unsubscribed', bounced or cleaned contacts from LeadManaging become 'cleaned' in Mailchimp. This ensures Mailchimp's compliance model is respected and prevents sending to non-consenting addresses.
LeadManaging
Lease Application
Mailchimp
Mailchimp Tag (reference only)
1:1LeadManaging lease application records (application status, screening result, approved amount) have no Mailchimp equivalent. We preserve this data as a structured tag (APPLICATION_STATUS: Approved / Pending / Denied) and a custom merge field (APPLICATION_DATE, SCREENING_SCORE) for reference. The actual leasing workflow must be managed outside Mailchimp.
LeadManaging
Owner / Assigned User
Mailchimp
Mailchimp Tag
1:1LeadManaging owner assignment (the leasing team member assigned to a prospect) migrates as an OWNER tag on the Mailchimp contact. This enables segmentation by assigned leasing agent for team-specific campaigns or routing follow-ups. If Mailchimp is used by multiple agents, tags can be used to filter the audience for agent-dashboard views.
LeadManaging
Tags / Labels
Mailchimp
Mailchimp Tag
1:1LeadManaging contact tags (property-specific labels, demographic tags, preference tags) migrate 1:1 as Mailchimp tags. Tag names are preserved exactly as stored in LeadManaging. Tag-based segmentation in Mailchimp replicates the audience filtering logic from LeadManaging. After migration, you can use Mailchimp's tag management interface to merge, rename, or retire tags as your marketing strategy evolves.

Migration approach
Audit LeadManaging schema and audience scope
FlitStack reads your LeadManaging data model to identify all standard and custom fields, lead stages, property associations, and tags. We also identify contacts without email addresses (which cannot import to Mailchimp) and contacts assigned to multiple properties (which may require audience splitting). The audit output is a migration plan listing every field, its Mailchimp target (merge field, tag, or note), and any data quality issues that need resolution before import.
Create Mailchimp merge fields and audience structure
Before any contact data moves, we create the required merge fields in your Mailchimp audience(s) based on the schema discovered in Step 1. If leads should be split into multiple audiences (e.g., by property or portfolio), we set up the audience structure now. Merge field creation is done via the Mailchimp Marketing API or documented as manual setup steps if your account lacks API permissions. This step also includes configuring tag groups for lead stage and lead source to keep tagging consistent.
Export LeadManaging contacts with field-level mapping and subscription status
We export all LeadManaging contacts via the platform's API or CSV export, applying the field mapping defined in the migration plan. Email addresses are validated for format and deliverability. Opt-out flags from LeadManaging are translated to Mailchimp member statuses (subscribed, unsubscribed, cleaned). Leads with ambiguous consent status are flagged for your review. Tags, notes, and activity history are bundled per contact for import in a single operation to maintain data integrity.
Run sample import and field-level diff
A representative sample (typically 200–500 contacts spanning all lead stages, property types, and custom field values) is imported first. We generate a field-level diff comparing source values in LeadManaging against what landed in Mailchimp, so you can verify merge field mapping, tag assignment, and status translation before committing the full dataset. Sample import validation typically runs within 4–8 hours. If any discrepancies appear, we adjust the mapping and re-run the sample until the data matches your expectations.
Full import with delta pickup and audit log
The full contact dataset migrates into Mailchimp. A delta-pickup window (24–48 hours) runs concurrently, capturing any contacts created or modified in LeadManaging during the migration window. Every import operation is logged with source record ID, destination contact ID, and field-level outcome. If reconciliation reveals mismatches, a rollback to the pre-migration state is available. After final validation, your Mailchimp audience is ready for campaign setup and automation rebuild.
