Overview

What this migration involves

Cliniko is a practice-management platform: it stores patient records, practitioner profiles, appointments, invoices, and custom intake fields. Mailchimp is an email-marketing platform: it recognizes contacts by email address and organizes them into audiences using tags, segments, and merge fields. These are fundamentally different data models — Cliniko has a relational healthcare schema with timestamps, clinical notes, and practitioner links; Mailchimp has a flat contact schema optimized for campaign targeting. FlitStack AI bridges this gap by mapping Cliniko patients to Mailchimp contacts (email as the join key), converting appointment dates and types to Mailchimp tags and merge fields, and surfacing the non-transferable automations that need manual rebuild in Mailchimp's automation builder. The migration runs via Cliniko's export API and Mailchimp's batch contacts API, with a sample-first approach and field-level diff before the full run commits. Workflows, appointment reminder sequences, and SMS campaigns do not migrate — they are outside the data layer and must be rebuilt using Mailchimp's automation tools.

What's pushing teams away

  • API access is tied to individual user permissions, meaning API keys inherit role-based access controls — a practitioner-key may not expose all records a migration requires, complicating bulk export scoping.
  • Cliniko's automation capabilities (e.g. appointment reminders, form-triggered updates) do not export; they must be manually rebuilt in the destination platform, increasing migration effort for workflow-heavy practices.
  • Large data exports generate in the background and can take considerable time during busy hours, which may delay migration cutover timelines for practices with high appointment volumes.
  • The platform lacks a native HubSpot or Salesforce CRM-style pipeline view for tracking patient leads or referral sources — practices that outgrow Cliniko often cite the need for a dedicated CRM layer.

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 Cliniko objects map to Mailchimp

Each row shows how a Cliniko 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.

Cliniko

Patient

maps to

Mailchimp

Contact (Mailchimp Audience)

1:1
Fully supported

Cliniko patients map directly to Mailchimp contacts using email address as the join key. First name, last name, phone, and address fields migrate as standard Mailchimp contact fields. Medical information (DOB, conditions, insurance) migrates as custom merge fields. Contacts without an email address cannot be created in Mailchimp and are flagged for manual review before the migration runs.

Cliniko

Location

maps to

Mailchimp

Tag (location-based)

1:1
Fully supported

Cliniko locations do not have a direct Mailchimp equivalent — Mailchimp has no location object on contacts. We apply a location-based tag to each contact during migration (e.g., TAG: Location — Downtown Clinic) so you can filter and segment by clinic in Mailchimp's audience view. For multi-location clinics with separate audience requirements, we can create one Mailchimp audience per location using location-scoped email queries from Cliniko.

Cliniko

Appointment

maps to

Mailchimp

Tag + Merge Field

1:1
Fully supported

Cliniko appointments (with type, date, status, and practitioner) have no native equivalent in Mailchimp's contact model. The most recent appointment date migrates as a DATE merge field (e.g., LASTVISIT). Appointment type names (Initial Consultation, Follow-up, New Patient Exam) migrate as tags on the contact. Next appointment dates are stored as a separate DATE merge field (NEXTAPT). Full appointment history remains in Cliniko and is not loaded into Mailchimp.

Cliniko

Practitioner

maps to

Mailchimp

Merge Field + Tag

1:1
Fully supported

Cliniko practitioners have names, titles, specialties, and email addresses but Mailchimp has no practitioner object for internal staff. We migrate practitioner name and specialty as text merge fields on the patient contact (e.g., MERGE5: Primary Practitioner, MERGE6: Specialty). Practitioners who are also patients get their practitioner role tagged. Practitioners who are not patients are exported as a separate reference list for your Mailchimp admin.

Cliniko

Invoice

maps to

Mailchimp

Merge Field (reference only)

1:1
Fully supported

Cliniko invoices track amounts, line items, payment statuses, and taxes — none of these have a place in Mailchimp's contact model. We preserve the most recent invoice total and payment status as optional merge fields (e.g., LASTINVOICE, PAYMENTSTATUS) for segmentation purposes (e.g., tag contacts with outstanding balances). Full invoice history stays in Cliniko.

Cliniko

Product / Service

maps to

Mailchimp

Tag (product interest)

1:1
Fully supported

Cliniko products and services (catalog items sold or used during appointments) have no native equivalent in Mailchimp. We tag contacts with the names of products or services they have received (e.g., TAG: Acupuncture — Initial Session) so you can segment for cross-sell campaigns in Mailchimp based on service history. Full product catalog data remains in Cliniko.

Cliniko

Custom Patient Field

maps to

Mailchimp

Merge Field

1:1
Fully supported

Cliniko custom fields for intake forms, clinical notes, and patient preferences require Mailchimp merge fields to be created before migration. Mailchimp enforces a 40-character field name limit and supports TYPE: text, number, date, phone, or address. Multi-select or array-type custom fields in Cliniko are flattened to a text merge field with pipe-delimited values. We handle field-type mapping and naming compliance during Mailchimp audience setup before the batch load runs.

Cliniko

Patient Note

maps to

Mailchimp

Contact Note

1:1
Fully supported

Cliniko patient notes are encrypted at rest and attached to patient records. Mailchimp contact notes are plain text visible to all account users. Sensitive clinical notes (treatment details, diagnoses, clinical flags) must remain in Cliniko for HIPAA compliance. Non-sensitive administrative notes migrate as Mailchimp contact notes during the batch load. We flag any note containing clinical keywords and route it to a Cliniko-only reference rather than the Mailchimp contact note field.

Cliniko

Patient Communication Preference

maps to

Mailchimp

Email Status + Merge Field

1:1
Fully supported

Cliniko tracks patient communication preferences for email, SMS, and phone. Mailchimp only has native email subscription status (subscribed / unsubscribed / cleaned). SMS and phone preferences migrate as custom merge fields (SMS_PREF, PHONE_PREF). Patients who are marked as email-subscribed in Cliniko are added to the Mailchimp audience with status: subscribed. We validate that the email subscription flag in Cliniko reflects genuine marketing consent before setting Mailchimp status.

Cliniko

Patient Tag / Label

maps to

Mailchimp

Tag

1:1
Fully supported

Cliniko patient tags (e.g., Referral — GP, Insurance — Private, VIP) map directly to Mailchimp tags since both platforms use a string-label tagging model on contacts. We preserve all Cliniko tags as Mailchimp tags during migration. Note: Mailchimp's tag limit per contact is 60 — if a Cliniko patient has more than 60 tags, we keep the 60 most-recently-applied and log the overflow for manual consolidation.

Cliniko

Appointment Type

maps to

Mailchimp

Tag (category)

1:1
Fully supported

Cliniko appointment types (e.g., Initial Consultation, Massage Therapy 60min, Physiotherapy Follow-up) define the service delivered at each booking. Mailchimp has no appointment-type object. Each unique appointment type from Cliniko becomes a Mailchimp tag applied to contacts who have had that appointment type (e.g., TAG: Appointment Type — Massage Therapy 60min). This lets you segment by service type for targeted re-booking campaigns in Mailchimp.

Cliniko

Insurance Provider

maps to

Mailchimp

Merge Field

1:1
Fully supported

Cliniko stores insurance provider and policy details per patient. Mailchimp has no native insurance field. Insurance provider name migrates as a text merge field (INSURANCE_PROVIDER). Policy number migrates as a separate text merge field (POLICY_NUMBER) if present. Policy expiration dates migrate as DATE merge fields. Full insurance records stay in Cliniko; Mailchimp merge fields serve as reference only for campaign targeting.

Pair-specific challenges

  • Mailchimp integration syncs globally across all locations, not per-location

    Cliniko's Mailchimp integration has a known limitation: it syncs patients globally without filtering by clinic location. Multi-location clinics report that every patient gets pulled into a single Mailchimp audience regardless of which branch they visited. When migration brings all locations' patients into one Mailchimp audience, contacts who visited two clinics become duplicates. FlitStack AI deduplicates by email across all Cliniko locations before the Mailchimp batch load and applies location-based tags (TAG: Downtown, TAG: Northside) so you can segment by clinic in Mailchimp without creating duplicate contact records. For teams that need fully separate audiences per location, we can create one Mailchimp audience per location using location-scoped queries from Cliniko's data export.

  • Healthcare data in Cliniko does not belong in Mailchimp's contact notes

    Cliniko stores treatment notes, clinical flags, diagnoses, and intake-form responses with encryption at rest. Mailchimp's contact notes field is plain text and visible to every user with access to the Mailchimp account. This creates a data-sensitivity mismatch — moving clinical notes into Mailchimp's contact note field exposes protected health information to users who should not see it, and may conflict with healthcare data-handling obligations. FlitStack AI detects clinical keywords in Cliniko patient notes during pre-migration scanning and routes those notes to a Cliniko-only reference export rather than the Mailchimp contact note field. Non-clinical administrative notes (e.g., 'Prefers morning appointments') do migrate as Mailchimp contact notes after keyword filtering.

  • Mailchimp merge fields have a 40-character name limit and no array type

    Cliniko custom fields for intake forms, clinical data, and multi-select preferences can have long names and store array or JSON-like values (e.g., a list of allergies or prior conditions). Mailchimp merge field names are capped at 40 characters and only support scalar types: text, number, date, phone, address, and URL. There is no array or multi-select field type in Mailchimp. Long Cliniko field names are truncated to 40 characters and made URL-safe during Mailchimp audience setup. Multi-select values are flattened to a pipe-delimited text string (e.g., 'Penicillin | Latex | Peanuts') stored in a text merge field. We handle field-type mapping and name compliance during Mailchimp audience setup before the batch load, and we document any truncation or flattening decisions in the migration plan.

  • Cliniko appointment reminders and SMS sequences do not migrate

    Cliniko's Mailchimp integration supports appointment reminders and basic SMS notifications, but these are configured as integration-level automations — not as data records in Cliniko's database. They have no export format and cannot be extracted as migration data. When you move to Mailchimp, appointment-reminder sequences, SMS follow-up flows, and any multi-step reminder logic built through the Cliniko integration must be rebuilt from scratch in Mailchimp's automation builder using appointment-date merge fields and time-based triggers. FlitStack AI documents your existing Cliniko reminder configuration (frequency, timing, message content) during the pre-migration audit and delivers an automation-rebuild reference guide for your Mailchimp admin.

  • Contacts without an email address cannot be created in Mailchimp

    Mailchimp requires a valid email address to create a contact — there is no way to add a contact without one. Cliniko occasionally has patients recorded with only a phone number, a partial name, or no contact information at all. These records appear in Cliniko's patient export but cannot be batch-loaded into Mailchimp. FlitStack AI flags all Cliniko patients missing an email address before the migration runs, reports the count and available fields (phone, name) so your team can attempt to obtain email addresses, and holds those records out of the initial batch load. Patients who later provide email addresses can be added through a Mailchimp signup form or re-processed through a secondary migration run.

Migration approach

Six steps for a successful Cliniko to Mailchimp data migration

  1. Extract Cliniko data and audit for migration readiness

    FlitStack AI uses Cliniko's Settings > Data exports and API access to extract patients, practitioners, appointments, appointment types, locations, and custom patient fields in parallel. We run a pre-migration audit: deduplicate patients by email across all locations, identify contacts missing email addresses, scan notes for clinical keywords, and count unique appointment types and practitioners. We deliver a data audit report before any Mailchimp audience setup begins so your team can review what will and will not migrate.

  2. Configure Mailchimp audiences and merge fields

    We create your Mailchimp audience (or one audience per location for multi-location setups) and pre-create all required merge fields using Cliniko field names as the reference label, mapped to Mailchimp's supported types. Field-name truncation, type conversion, and array-flattening are applied at this stage. Double opt-in settings are configured based on your email consent data in Cliniko. Tags for location names, appointment types, and practitioner names are pre-created in the Mailchimp audience so the batch load can apply them without errors.

  3. Run a sample migration with field-level diff

    A representative slice of 50–100 Cliniko patient records migrates to Mailchimp first. We verify that merge fields populate with the correct data types (dates in MM/DD format, phone numbers in international format where needed), special characters in names and addresses are preserved, location tags are applied correctly, and contacts without email are properly excluded. A field-level diff is generated comparing source Cliniko values against Mailchimp contact values for every mapped field. You review the diff and approve before the full migration runs.

  4. Execute full batch migration with delta pickup

    The full Cliniko patient dataset loads into Mailchimp via Mailchimp's batch contacts API. Appointment type names are applied as tags on each contact, location names are applied as tags, practitioner names are written to merge fields, and email subscription flags set contact statuses. A delta-pickup window (24–48 hours after batch completion) captures any Cliniko patients added or updated during the migration window. FlitStack AI posts a validation report: contact count vs. source count, tag application summary, merge field fill rate, and a list of any records that failed to load with error reasons.

  5. Deliver automation-rebuild reference and post-migration handoff

    We document every Cliniko integration automation (appointment reminders, SMS flows, Mailchimp sync rules) discovered during the pre-migration audit and deliver it as a rebuild reference for Mailchimp's automation builder. This includes trigger logic, timing rules, message content, and any conditional branches. Post-migration, FlitStack AI provides a contact-level audit log of all migrated records and a one-click rollback option if reconciliation identifies data issues. Ongoing Mailchimp segmentation by location, appointment type, or practitioner can be built using the tags and merge fields we pre-configured during migration.

Strengths

  • Single flat-rate plan with unlimited patients, users, locations, and storage — no per-seat or per-record throttling.
  • Built-in invoicing, appointment scheduling, treatment notes, and reporting in one cloud-hosted application.
  • Telehealth included at no extra cost, launched and maintained without a paywall.
  • Admin-accessible data export panel covering appointments, patients, invoices, transactions, and more.
  • REST API with HTTPS enforcement, JSON responses, and a published OpenAPI schema for programmatic access.

Weaknesses

  • API keys inherit the role-based permissions of the user they belong to, so a read-only or practitioner-level key may not expose all records needed for a full migration export.
  • Form template builders (the configuration for patient intake forms) are not exported via the data panel and must be recreated manually in the destination.
  • The old Appointments export is deprecated; the replacement Reports-based export has different column layouts that require mapping adjustments during migration scoping.
  • Background export generation for large datasets can be slow during busy hours, with no real-time progress API — only email notification on completion.
  • No native automation export; appointment reminders, form-triggered patient field updates, and similar rules must be manually rebuilt in the destination system.

Most Cliniko-to-Mailchimp migrations complete in 24–48 hours for under 5,000 patient records. Data extraction from Cliniko takes 1–3 hours depending on record volume, Mailchimp audience setup takes 1–2 hours, and the batch load itself runs in 2–6 hours. Larger datasets over 10,000 records, multi-location deduplication, or extensive custom field creation extend the timeline to 3–5 days. The longest single step is typically the pre-migration audit and location deduplication for multi-location clinics.
