Overview
Ziggu and Mailchimp occupy fundamentally different functional categories — Ziggu is a client-portal and project-management platform for property developers, while Mailchimp is an email service provider. The migration therefore centers on a single data operation: extracting Ziggu's contacts, companies, and custom client properties, then importing them into a Mailchimp audience with equivalent merge fields. We do not migrate Ziggu projects, conversation threads, document libraries, approval workflows, or task trackers — those have no Mailchimp equivalent. We preserve all contact-level data including names, email addresses, phone numbers, company associations, custom property values, tags, and opt-in timestamps. The migration runs via Mailchimp's bulk import API, with a 24–48 hour delta window to capture any contact changes in Ziggu during cutover. Owner resolution is not applicable since Mailchimp contacts are not assigned to named users. Before import, we audit the Ziggu contact schema, create matching Mailchimp merge fields, and validate data types to ensure accurate mapping. Duplicate detection uses email addresses as the primary key; any contacts lacking a valid email are excluded and reported. Custom property values are transformed to the appropriate Mailchimp field type (text, date, dropdown, or number), and any overflow beyond Mailchimp's 40-merge-field limit is handled by storing extra data in a JSON-encoded NOTES field. Throughout the process, FlitStack AI uses read-only API access to Ziggu, ensuring your team can continue working without interruption.

Object mapping
Each row shows how a Ziggu 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.
Ziggu
Contact
Mailchimp
Mailchimp Contact (Audience Member)
1:1Every Ziggu contact maps to a Mailchimp audience member. Email address is the unique identifier used for deduplication. Contacts without a valid email address are excluded from migration and flagged in the pre-migration audit report. All other contact fields such as name, phone, and custom properties are transferred as merge fields or tags to preserve full profile data.
Ziggu
Company
Mailchimp
Merge Field (COMPANY) + Tag
many:1Ziggu company name maps to the standard Mailchimp COMPANY merge field. If a contact has multiple associated companies in Ziggu, the primary company is used for the merge field and additional companies are added as tags (e.g., 'Company: Acme Corp').
Ziggu
Project
Mailchimp
Mailchimp Tag or Audience Segment
1:1Ziggu projects have no direct Mailchimp equivalent. We tag contacts by their associated project name (e.g., 'Project: Riverside Development') or create a Mailchimp segment filtered by that tag so you can target project-specific campaigns. If multiple projects apply, each is added as a separate tag, allowing segmentation across the entire development portfolio.
Ziggu
Custom Contact Property
Mailchimp
Mailchimp Merge Field
1:1Each Ziggu custom contact property (e.g., Unit Number, Selection Status, Survey Score) requires a corresponding Mailchimp merge field to be created before import. Field type mapping: text properties become Mailchimp text fields; date properties become date fields; pick-list properties become dropdown or radio merge fields.
Ziggu
Tag
Mailchimp
Mailchimp Tag
1:1Ziggu contact tags migrate 1:1 to Mailchimp tags on the same contact record. Tags are preserved exactly as named in Ziggu, including any categorization prefixes (e.g., 'Status: Active Buyer'). This ensures that segmentation logic built on tag names in Ziggu maps directly to Mailchimp audience segments without manual renaming.
Ziggu
Opt-in / Consent Timestamp
Mailchimp
Mailchimp Stats / Timestamp Merge Field
1:1Ziggu does not natively track GDPR-style consent timestamps, but if your Ziggu setup includes a consent property or registration date, we preserve it as a custom datetime merge field (OPTIN_DATE__c) in Mailchimp for compliance segmentation. This field enables you to filter contacts based on when consent was given, supporting GDPR and CAN-SPAM compliance requirements.
Ziggu
Conversation / Message Thread
Mailchimp
No Equivalent
1:1Ziggu conversation threads and client messaging history do not migrate. Mailchimp has no concept of threaded conversation storage. If message content is business-critical, export Ziggu conversations as a PDF report separately — FlitStack can include this as a companion deliverable but it is not a Mailchimp contact import.
Ziggu
Document / File Attachment
Mailchimp
No Equivalent
1:1Ziggu documents and file attachments have no Mailchimp equivalent. Files stored in Ziggu cannot be migrated into Mailchimp. We recommend downloading the full Ziggu document library as a ZIP archive before migration — this is outside the scope of the Mailchimp contact migration but we can coordinate timing.
Ziggu
Approval / Task Record
Mailchimp
No Equivalent
1:1Ziggu approval workflows and task records are project-management constructs that do not translate to Mailchimp. Task ownership and approval status in Ziggu are not surfaced in Mailchimp — those processes must be re-established using Mailchimp's customer-journey automations if desired. This ensures that your team can rebuild approval logic in Mailchimp using triggers such as tag additions or field updates.
Ziggu
Survey Response
Mailchimp
Merge Field + Tag
1:1Ziggu survey responses stored as contact properties map to Mailchimp merge fields (for numeric or text responses) or tags (for categorical responses like NPS detractor/promoter). NPS scores can also be stored as a number merge field for segmentation. This mapping preserves survey insights and enables targeted campaigns based on respondent categories.
Ziggu
Phone Number
Mailchimp
Merge Field (PHONE) or SMSConsent
1:1Ziggu phone numbers map to the standard Mailchimp PHONE merge field. SMS marketing consent must be handled separately — Mailchimp requires explicit SMS opt-in that is independent of email consent tracked in Ziggu.
Ziggu
Unit / Property Reference
Mailchimp
Merge Field (UNIT) + Tag
1:1For property developers, Ziggu stores which unit a client is associated with. This maps to a custom UNIT merge field in Mailchimp (e.g., 'Unit 4B, Riverside'). If a contact is associated with multiple units, additional units are added as tags. This approach lets you segment by unit for targeted launch announcements and post-handover communications.

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.
Ziggu gotchas
Deactivated projects lock tasks and files but keep conversations open
Per-active-project pricing creates a minimum portfolio cost
Add-ons scale per active unit, not per project
No public API means migration runs through manual export workflows
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
Pre-migration audit and contact extraction from Ziggu
We authenticate against the Ziggu API using your account credentials and extract all contact records, company records, tags, and custom property schemas. We generate a pre-migration audit report showing total contacts, contacts without email addresses (excluded), duplicate email addresses, and the full list of custom property names and data types. This report drives the merge-field creation scope in Mailchimp before any import begins.
Mailchimp audience setup and merge field configuration
We create the target Mailchimp audience (or multiple audiences if your scoping call identified a multi-audience strategy) and configure all required merge fields before importing data. Merge fields are created with matching data types — text fields for free-text properties, dropdowns for pick-lists, date fields for timestamps. Tags from Ziggu are noted for bulk application during import. If your setup exceeds Mailchimp's 40-merge-field limit, we present the prioritization options and get your sign-off before proceeding.
Sample migration with field-level validation
A representative slice of contacts — typically 100–500 records — is imported first into the Mailchimp audience. We generate a field-level diff comparing source values in Ziggu against the imported values in Mailchimp for every merge field and tag. You verify that custom properties, tag assignments, company associations, and opt-in timestamps landed correctly before we commit to the full migration run.
Full migration with delta-pickup window
The full contact set is imported into Mailchimp using Mailchimp's bulk import API with upsert semantics (existing contacts are updated, new contacts are created). A delta-pickup window of 24–48 hours runs concurrently with your final days in Ziggu — any contacts created or modified in Ziggu during cutover are pulled into Mailchimp so the audience reflects Ziggu's final state. All operations are logged in an audit trail. One-click rollback reverts the Mailchimp audience to its pre-migration state if reconciliation fails.
Post-migration companion deliverables and rebuild reference
After the Mailchimp audience is confirmed, we deliver: (1) a Ziggu document library ZIP archive downloaded from Ziggu before account access is revoked; (2) a Ziggu workflow export documenting your approval workflows, task automations, and notification rules as a rebuild reference for Mailchimp Customer Journeys; (3) a contact migration summary report with counts, excluded records, and merge-field mapping confirmation. Your team uses the rebuild reference to re-create high-priority automations in Mailchimp independently or with FlitStack's automation-rebuild add-on.
