Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Ziggu

What's pushing teams away

  • Teams outgrow the platform when project volumes exceed tier minimums — the per-active-project pricing model becomes expensive at scale and forces difficult decisions about which legacy projects to deactivate.
  • The lack of a public REST API means Zapier/Make integrations must be built around screen scraping or webhook triggers, creating fragile automations that break on UI updates.
  • Property developers with complex multi-entity corporate structures find Ziggu's flat account model insufficient — there is no parent-company hierarchy or multi-subsidiary consolidation view.
  • When a project is deactivated it becomes read-only and cannot accept new tasks, conversations, or file uploads, which creates friction in post-handover support scenarios where the development team still needs to communicate with buyers.

Choosing

Mailchimp

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How Ziggu objects map to Mailchimp

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

maps to

Mailchimp

Mailchimp Contact (Audience Member)

1:1
Fully supported

Every 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

maps to

Mailchimp

Merge Field (COMPANY) + Tag

many:1
Fully supported

Ziggu 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

maps to

Mailchimp

Mailchimp Tag or Audience Segment

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

Mailchimp Merge Field

1:1
Fully supported

Each 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

maps to

Mailchimp

Mailchimp Tag

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

Mailchimp Stats / Timestamp Merge Field

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

No Equivalent

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

No Equivalent

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

No Equivalent

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

Merge Field + Tag

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

Merge Field (PHONE) or SMSConsent

1:1
Fully supported

Ziggu 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

maps to

Mailchimp

Merge Field (UNIT) + Tag

1:1
Fully supported

For 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.

Pair-specific challenges

  • Ziggu's project-centric data model flattens into a single Mailchimp audience

    Ziggu stores contacts in the context of projects — a client may be associated with multiple projects, units, and conversations simultaneously. Mailchimp has a flat audience model: each contact exists once per audience with merge fields and tags. We resolve this by tagging contacts with their associated project names and using the primary project as the main context. If you need project-level isolation, you would need separate Mailchimp audiences per project, which multiplies your contact-based pricing — we surface this decision in the pre-migration scoping call.

  • Mailchimp's 40-merge-field limit per audience constrains heavily customized Ziggu setups

    Ziggu supports unlimited custom contact properties (especially when add-ons like Surveys, Financials, or Sales are active). Mailchimp caps standard merge fields at 40 per audience. For setups with more than 40 custom Ziggu properties, we prioritize the most business-critical fields for merge field creation and store remaining properties as JSON-encoded strings in a NOTES merge field — or recommend splitting contacts across multiple Mailchimp audiences by property group. This limit is a Mailchimp platform constraint, not a migration-tool limitation.

  • Ziggu conversation history and document attachments have no Mailchimp equivalent

    Client communication threads and file attachments stored in Ziggu cannot be imported into Mailchimp — Mailchimp is an email marketing platform, not a client portal or document management system. We export Ziggu conversations as a structured report and documents as a ZIP archive as companion deliverables, but these do not land inside Mailchimp. Your team should download the Ziggu document library before account closure, as access is revoked at the source.

  • SMS marketing consent requires separate re-permissioning in Mailchimp

    Ziggu may store phone numbers and in some setups track SMS or WhatsApp consent. Mailchimp's SMS marketing requires explicit, independent opt-in under TCPA and GDPR compliance rules — email consent captured in Ziggu does not transfer to SMS consent. We preserve the phone number as a Mailchimp merge field but flag that SMS campaigns require a fresh opt-in workflow. Mailchimp also offers a paid SMS add-on separate from email plan pricing, which your team should account for in the Mailchimp cost model.

  • Ziggu approval workflows and task routing do not migrate to Mailchimp automations

    Ziggu's internal approval workflows (e.g., client selection approvals, milestone sign-offs) and task routing automations are project-management constructs that map to Mailchimp's customer-journey automations only in the most abstract sense. Mailchimp automations trigger on subscriber behavior (email opens, link clicks, purchases) — not on approval statuses or project task completions. We document your Ziggu workflow logic as a rebuild reference, but those automations must be re-created in Mailchimp from scratch using Mailchimp's Customer Journey builder.

Migration approach

Six steps for a successful Ziggu to Mailchimp data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Strengths

  • Per-project billing aligns cost to active workload — completed projects can be deactivated without losing history.
  • Built-in client portal with 24/7 transparency reduces the back-and-forth email volume between development teams and buyers.
  • Conversations remain writable on deactivated projects, keeping post-handover support communication open.
  • Structured approval workflows with deadline tracking help property developers collect client decisions without chasing.
  • Survey module integrates NPS and custom question collection at defined project milestones.

Weaknesses

  • No public REST API documented — integrations must rely on webhook triggers or manual export workflows.
  • Per-active-project pricing with tier minimums (10/15/25) makes the platform expensive to maintain for large legacy project portfolios.
  • Deactivated projects become read-only across tasks and files, limiting post-handover activity.
  • Partner Portal, Multi-unit Projects, Financials, Sales, and Surveys are all paid add-ons priced per active unit, layering costs quickly.
  • Flat account structure with no parent-company or multi-subsidiary hierarchy for larger property groups.

Most Ziggu-to-Mailchimp migrations complete in 48–72 hours for under 50,000 contacts. The pre-migration audit and Mailchimp audience setup typically take 4–8 hours of planning work before data movement begins. Larger contact volumes above 500,000 or setups requiring multi-audience architecture extend to 5–7 days. Merge field configuration is the longest planning step when Ziggu has heavy custom property schemas. The delta-pickup window adds a 24–48 hour buffer after the bulk import to capture any late changes in Ziggu, ensuring the Mailchimp audience reflects the final state at go-live.
