Overview
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.
Every standard and custom field arrives verified.

Object mapping
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
Mailchimp
Contact (Mailchimp Audience)
1:1Cliniko 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
Mailchimp
Tag (location-based)
1:1Cliniko 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
Mailchimp
Tag + Merge Field
1:1Cliniko 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
Mailchimp
Merge Field + Tag
1:1Cliniko 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
Mailchimp
Merge Field (reference only)
1:1Cliniko 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
Mailchimp
Tag (product interest)
1:1Cliniko 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
Mailchimp
Merge Field
1:1Cliniko 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
Mailchimp
Contact Note
1:1Cliniko 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
Mailchimp
Email Status + Merge Field
1:1Cliniko 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
Mailchimp
Tag
1:1Cliniko 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
Mailchimp
Tag (category)
1:1Cliniko 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
Mailchimp
Merge Field
1:1Cliniko 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.

Migration approach
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.
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.
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.
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.
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.
