Overview
LionDesk is a real estate CRM focused on contacts, drip campaigns, and deal pipelines. Mailchimp is an email marketing platform built around audiences, campaigns, and customer journeys. This migration transfers LionDesk contacts — including names, emails, phone numbers, custom field values, and tags — into a Mailchimp audience, preserving the original data types and structures. Deal stages, task assignments, and drip sequences have no direct Mailchimp equivalents and must be rebuilt using Mailchimp's Journey Builder and segmentation tools. The process pulls data through LionDesk's API, validates email addresses, deduplicates records, and transforms fields to match Mailchimp's merge‑field schema. API credentials are transmitted over TLS, and read‑only access ensures no changes to LionDesk during extraction. A test migration with field‑level comparison runs before the full cutover, followed by a 24–48 hour delta window that captures any LionDesk changes made during the switch. Audit logs record every operation, and one‑click rollback is available if reconciliation fails, ensuring data integrity throughout the cutover. Optional pre‑migration services include contact hygiene, duplicate resolution, and custom field type mapping to further align the schema.
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 LionDesk 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.
LionDesk
Contact
Mailchimp
Audience Member
1:1LionDesk contacts map to Mailchimp audience members. Email address is the unique identifier — each LionDesk contact becomes one member record in your target Mailchimp audience. Duplicate email addresses are flagged during extraction and resolved before loading. The primary company association is stored in the COMPANY merge field for each audience member.
LionDesk
Contact Custom Fields
Mailchimp
Merge Fields
1:1LionDesk custom fields (Text, Number, Date, Dollar Amt types) are created as matching Mailchimp merge fields in the target audience. Data type is preserved — number fields stay numeric, dates stay date-typed — so segmentation and filtering in Mailchimp work correctly after migration.
LionDesk
Contact Tags
Mailchimp
Tags
1:1LionDesk tags applied to contacts migrate as Mailchimp tags on the same audience member. Tags are preserved as-is and can immediately drive segmentation, campaign targeting, and Customer Journey triggers without manual re-tagging. Tags are transferred exactly as they appear; case differences produce separate tags. If you use tag groups, we can apply a consistent prefix so segmentation remains clear in Mailchimp.
LionDesk
Contact Notes
Mailchimp
Notes Merge Field
1:1LionDesk notes migrate to a dedicated text merge field labeled LD_Notes for reference. Mailchimp has no native notes object for members, so the content is stored as a text field. Note truncation occurs for content exceeding 255 characters — flagged in the field-level diff.
LionDesk
Deal / Pipeline Stages
Mailchimp
No equivalent
1:1LionDesk deal pipelines and stage values have no direct Mailchimp equivalent. Mailchimp is an email marketing platform, not a CRM — deal names, amounts, and pipeline stages cannot be stored as structured records. These are documented as rebuild items. If you need to preserve deal amounts or stage names, we can create custom number or text merge fields to store these values, then use them for segmentation or reporting in Mailchimp.
LionDesk
Tasks / Reminders
Mailchimp
No equivalent
1:1LionDesk task assignments and reminders cannot migrate to Mailchimp, which has no task management module. We recommend exporting the task list as a CSV before cutover so your team can recreate critical follow-ups manually in their preferred task tool. The exported CSV includes due dates, assignees, and task descriptions to facilitate straightforward recreation in tools such as Asana, Trello, or a spreadsheet.
LionDesk
Drip Campaigns / Sequences
Mailchimp
Customer Journeys
1:1LionDesk drip campaigns are built on a different automation model than Mailchimp Customer Journeys. There is no direct translation between the two. We export campaign definitions as a structured reference document so your Mailchimp admin can rebuild sequences in Journey Builder.
LionDesk
Company Records
Mailchimp
No equivalent (COMPANY merge field only)
1:1Mailchimp has no native company or account object — contacts are flat records within an audience. The primary company name maps to the COMPANY merge field. If you rely on LionDesk company associations for segmentation, those must be reconstructed using merge fields or tags in Mailchimp.
LionDesk
SMS Message Logs
Mailchimp
No equivalent
1:1LionDesk SMS conversations and logs cannot be stored in Mailchimp, which is email-focused. We recommend exporting SMS history as a CSV using LionDesk's native export function before cutover for compliance and record-keeping purposes. The CSV export can be used for compliance audits, regulatory retention requirements, or imported into a dedicated SMS platform if you decide to continue texting through a third-party service.
LionDesk
Video Email History
Mailchimp
No equivalent
1:1LionDesk video email files do not transfer to Mailchimp. If video content is critical to your outreach, host videos externally and embed links in your Mailchimp campaigns. The video files themselves remain in LionDesk until account deprovisioning. If you need to keep video content accessible after deprovisioning, download the files from LionDesk before the account is closed, and store them in a cloud drive or media library.

Migration approach
Extract LionDesk contacts via API
FlitStack AI authenticates to LionDesk using your API credentials and extracts all contact records, including standard fields, custom field definitions, custom field values, associated tags, and company associations. The extraction runs in read-only mode — no LionDesk data is modified during the export. We capture the full contact payload including timestamps, owner references, and any linked notes so nothing is missed before the schema mapping phase begins.
Audit custom fields and create Mailchimp merge fields
We inventory every LionDesk custom field definition — type, name, data format, and usage across contacts — and create matching merge fields in your target Mailchimp audience. Text fields become text merge fields, numbers become number merge fields, and dates become date merge fields. The Mailchimp merge field schema is fully set up before any contact data is loaded, so the first migration run has a complete destination schema to map against.
Run a test migration with field-level diff
A representative batch of contacts — typically 100–500 records spanning different tag groups, custom field usage patterns, and note lengths — migrates first. We generate a field-level diff comparing every source field against its destination merge field, surfacing truncated text, missing values, tag mismatches, and any custom field gaps. You review the diff and approve or adjust the field mapping before the full run commits. This step catches the 255-character truncation issue before it affects your entire list.
Execute full migration with delta-pickup window
The full contact list loads into your Mailchimp audience. A delta-pickup window of 24–48 hours captures any LionDesk contacts created or modified during the cutover, ensuring Mailchimp reflects LionDesk's final state at go-live. Audit logs record every insert and update operation, and one-click rollback is available if the Mailchimp audience does not reconcile with your expected record counts or field values.
Deliver automation rebuild reference and post-migration verification
We export your LionDesk drip campaign definitions and task list as structured documentation — trigger logic, stage sequences, delay rules, and email content references — for your Mailchimp admin to use when rebuilding in Journey Builder. Post-migration, we run a final count verification comparing LionDesk contact totals against Mailchimp audience member counts and surface any gaps for manual review. We also flag any contacts with truncated notes for your team to handle.
