Overview
NeoDeck Holdings is a healthcare CRM and EHR platform built around patient records, providers, appointments, and billing workflows. Its data model stores patient contacts, provider objects, appointment metadata, insurance fields, and custom clinical properties. Mailchimp's audience model is a flat contact list with optional custom merge fields — designed for marketing sends, not clinical records. FlitStack AI extracts consented patient contacts and provider records from NeoDeck via its API, transforms them into Mailchimp contacts, and creates custom merge fields for any healthcare-specific properties that have no native Mailchimp equivalent. We preserve the original marketing-opt-in timestamp on each contact and carry over consent flags as Mailchimp marketing-permission statuses. Workflows, appointment reminder sequences, and billing automation rules do not migrate — Mailchimp's automation builder requires a fresh rebuild. We export your NeoDeck workflow definitions as a reference document for your team. Custom clinical fields, insurance carriers, and provider attribution data migrate as merge fields, enabling segmentation by provider, insurance tier, and patient type in Mailchimp campaigns.
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 NeoDeck Holdings 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.
NeoDeck Holdings
Patient Contact
Mailchimp
Mailchimp Contact (Audience Member)
1:1NeoDeck patient contact records map directly to Mailchimp contacts in your target audience. The patient's email address is the required key — contacts without a valid email address are excluded from migration. We validate email deliverability before inserting into Mailchimp.
NeoDeck Holdings
Patient First Name
Mailchimp
Mailchimp FNAME Merge Field
1:1Direct map. Mailchimp's FNAME merge field is a standard field on every audience. We populate it from NeoDeck's patient first-name property. If the source field is empty, the contact is created without FNAME and tagged as 'incomplete name' in Mailchimp.
NeoDeck Holdings
Patient Last Name
Mailchimp
Mailchimp LNAME Merge Field
1:1Direct map similar to FNAME. LNAME maps directly from NeoDeck's patient last-name property. Incomplete last names are permitted in Mailchimp but flagged for your team's post-migration review. This ensures you can follow up to complete missing contact information without blocking the migration.
NeoDeck Holdings
Patient Email Address
Mailchimp
Mailchimp EMAIL Field (required)
1:1The email address is the primary key in Mailchimp and must be present on every contact. We deduplicate by email during migration — if NeoDeck has duplicate patient records for the same email, we create one Mailchimp contact and merge the other fields. All associated tags and merge field values from duplicate records are consolidated into the single contact.
NeoDeck Holdings
Patient Phone Number
Mailchimp
Mailchimp Phone Number Merge Field
1:1Direct map to Mailchimp's standard phone field. Phone numbers migrate regardless of your SMS capabilities status — if SMS is not yet enabled, the field populates but remains inactive until you activate Mailchimp SMS. Note that Mailchimp phone numbers are used for SMS campaigns only if your account has SMS capabilities enabled.
NeoDeck Holdings
Provider Name
Mailchimp
Mailchimp Custom Merge Field (PROVIDER_NAME)
1:1NeoDeck's provider objects do not have a native equivalent in Mailchimp. We create a PROVNAME merge field on the Mailchimp audience and populate it with the provider name associated with each patient record. You can use this field to segment patients by their care provider in Mailchimp campaigns, enabling targeted newsletters or provider-specific health tips.
NeoDeck Holdings
Insurance Carrier
Mailchimp
Mailchimp Custom Merge Field (INS_CARRIER)
1:1Insurance carrier maps to a custom INS_CARRIER merge field. NeoDeck stores carrier as a text field; we map it directly. If your NeoDeck setup uses an insurance-carrier pick-list, we apply value-mapping to ensure consistent capitalization and naming across all migrated records. This prevents segmentation issues caused by inconsistent carrier naming.
NeoDeck Holdings
Patient Type / Category
Mailchimp
Mailchimp Custom Merge Field (PATIENT_TYPE)
1:1NeoDeck patient type values such as 'New Patient', 'Returning', or 'Specialty Care' have no Mailchimp equivalent. We create a PATIENT_TYPE pick-list merge field and map values directly. This enables you to run onboarding drip sequences for new patients in Mailchimp and segment returning patients for follow-up care campaigns.
NeoDeck Holdings
Marketing Consent Flag
Mailchimp
Mailchimp Marketing Permission Status
1:1NeoDeck's marketing consent flag maps to Mailchimp's contact status. Contacts with explicit marketing consent in NeoDeck are inserted as 'subscribed' in Mailchimp. Contacts without consent are inserted as 'non-subscribed' — Mailchimp will not send marketing emails to these contacts without a re-permission campaign. Re-engagement campaigns require a separate permission-capture workflow in Mailchimp before these contacts can receive sends.
NeoDeck Holdings
NeoDeck Tags / Labels
Mailchimp
Mailchimp Tags
1:1NeoDeck labels on patient records such as 'appointment-reminder', 'billing-followup', or 'wellness-series' migrate as Mailchimp tags. Tags are additive — if a patient has multiple NeoDeck labels, all apply as tags in Mailchimp. We recommend reviewing tag names post-migration to consolidate duplicates and establish a consistent tagging taxonomy for your marketing operations.
NeoDeck Holdings
Last Visit Date
Mailchimp
Mailchimp Custom Merge Field (LAST_VISIT)
1:1Mailchimp has no native appointment or visit concept. We create a LAST_VISIT date merge field and populate it from NeoDeck. This supports re-engagement automations — for example, you can configure Mailchimp to send re-engagement campaigns to contacts whose LAST_VISIT is more than 90 days ago, targeting lapsed patients for follow-up appointments.
NeoDeck Holdings
Billing Status
Mailchimp
Mailchimp Custom Merge Field (BILL_STATUS)
1:1NeoDeck billing status values such as 'paid', 'pending', or 'insurance-submitted' have no native Mailchimp equivalent. We create a BILLSTATUS merge field and map values directly. You can use this field for conditional content in billing-related Mailchimp campaigns — for example, sending different messages to patients with 'pending' versus 'paid' status.
NeoDeck Holdings
Custom Clinical Fields
Mailchimp
Mailchimp Custom Merge Fields
1:1NeoDeck custom patient properties such as care program enrollment, referral source, and preferred contact method migrate as custom merge fields in Mailchimp. Mailchimp allows up to 30 merge fields per audience — if your NeoDeck schema exceeds this, we prioritize the fields used in your most important segmentation rules and surface the remainder for a second-pass migration.
NeoDeck Holdings
Patient Address Object
Mailchimp
Mailchimp Address Merge Fields (ADDR1, CITY, STATE, ZIP)
1:1NeoDeck stores addresses as a structured object. Mailchimp has separate ADDRESS merge fields (ADDR1, CITY, STATE, ZIP) plus a generic ADDRESS field. We split NeoDeck's address into the standard Mailchimp address fields. If NeoDeck stores a two-line address (street + suite), the second line is appended to ADDR1 or placed in a custom merge field per your preference.
NeoDeck Holdings
Appointment Reminder Workflow
Mailchimp
Not Migrated (Rebuild in Mailchimp)
1:1NeoDeck appointment reminder workflows have no direct Mailchimp equivalent. We export the workflow definition including trigger conditions, timing intervals, and message content as a reference document. Your team rebuilds the automation in Mailchimp Customer Journeys using the exported definitions as a blueprint. The document includes step-by-step logic so your Mailchimp partner can replicate the workflow accurately.

Migration approach
Audit NeoDeck schema and validate consent flags before any data moves
FlitStack AI connects to NeoDeck via API using scoped read credentials. We pull a full inventory of patient contact fields, custom properties, provider records, and appointment metadata. We specifically audit the marketing consent field — identifying contacts with explicit consent, contacts without consent, and contacts where the field is null or uses a non-standard value. Your team sets the consent-handling rule (subscribed / non-subscribed / exclude) before extraction begins.
Design Mailchimp audience structure and create merge fields matching NeoDeck schema
We create the Mailchimp audience (or audiences for multi-location setups) and add all required merge fields before data lands. Merge field names follow Mailchimp's character limits (10 characters max, uppercase). For pick-list fields from NeoDeck, we pre-populate the merge field options so Mailchimp validates incoming values correctly. The audience is set to single-opt-in or double-opt-in based on your consent-handling configuration.
Extract patient contacts and provider data, transform to Mailchimp contact format
FlitStack extracts consented patient contacts, provider names, insurance fields, and custom properties from NeoDeck via the authenticated API connection. We deduplicate contacts by email address, split multi-value address objects into Mailchimp's separate address fields (ADDR1, CITY, STATE, ZIP), and map NeoDeck labels to Mailchimp tags. Each contact carries its original opt-in timestamp as a custom merge field and a SOURCE_SYSTEM_ID__c field containing the NeoDeck patient ID for traceability and future delta synchronizations.
Run sample migration with field-level diff against Mailchimp audience
A representative sample of 100–500 contacts migrates into the Mailchimp audience first as a validation pass. We generate a field-level diff report showing every mapped value as it appears in NeoDeck versus how it rendered in Mailchimp after transformation. You verify merge field rendering, tag application, consent status assignment, and deduplication behavior across the sample. We adjust the field mapping configuration based on your findings before committing the full production migration run.
Execute full migration with delta-pickup window and audit log
The full contact set migrates into the target Mailchimp audience following approval of the sample migration results. A delta-pickup window of typically 24–48 hours captures any new NeoDeck contacts or consent flag updates that occurred during the cutover window. FlitStack produces a comprehensive audit log documenting every record inserted, updated, or skipped with detailed reason codes. One-click rollback reverts the Mailchimp audience to its pre-migration state if reconciliation reveals data quality issues requiring correction.
