Overview
Evatic stores customer relationships as contact records tied to service contracts, asset hierarchies, and service-ticket histories. Mailchimp models contacts as subscriber records inside an Audience, with merge fields for custom properties and tags for categorical labeling. The migration maps Evatic customers to Mailchimp contacts, preserving email addresses, names, phone numbers, and company affiliations as native Mailchimp fields. Evatic custom fields (service tier, contract renewal date, equipment type) become Mailchimp merge fields (MERGEn-style) so segmentation by service category works immediately after cutover. Service-ticket history and asset records do not map to native Mailchimp objects — FlitStack surfaces these as tags on the contact record (e.g., 'HVAC-Contract-2025', 'Premium-Support') and preserves the raw data as a JSON blob in a 'Service_History__c' custom contact field for reference. Mailchimp has no equivalent to Evatic's multi-contact service-ticket model; contacts with multiple open tickets get the union of applicable tags. We use Mailchimp's REST API v3 for the migration, respecting rate limits and handling duplicate detection by email address. Workflows, automation sequences, and contract-renewal triggers in Evatic do not migrate — they must be rebuilt in Mailchimp's automation builder. The delta-pickup window captures any new Evatic contacts created during cutover.

Object mapping
Each row shows how a Evatic 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.
Evatic
Customer
Mailchimp
Contact (inside Audience)
1:1Evatic Customer maps directly to a Mailchimp Contact. Email address is the unique key — contacts with duplicate emails across Evatic records are flagged for resolution before migration. First name, last name, phone, and company map to Mailchimp's native contact fields.
Evatic
Customer Email
Mailchimp
Contact Email Address
1:1Email is the primary identifier in Mailchimp and the deduplication key for migration. If Evatic stores multiple email addresses per customer, the primary email maps to the contact and secondary addresses surface as a custom merge field for reference. This approach ensures each contact remains unique and traceable across the Audience.
Evatic
Customer Custom Fields
Mailchimp
Merge Fields
1:1Evatic custom fields on Customer records (e.g., service_tier, contract_type, region) map to Mailchimp merge fields. We create merge fields matching the Evatic field type — text, date, number, or dropdown. Mailchimp allows up to 80 merge fields per Audience, and we prioritize the most relevant fields to stay within that limit.
Evatic
Contract
Mailchimp
Tags + Custom Merge Field
1:1Evatic contracts do not map to a native Mailchimp object. Each active contract generates a tag on the linked customer contact (e.g., 'Contract-Type: Preventive-Maintenance', 'Contract-Status: Active'). Contract end date migrates as a date merge field for renewal-triggered segmentation, and the nearest future end date is stored in the CONTRACTEND field.
Evatic
Service Ticket
Mailchimp
Tags (no native equivalent)
1:1Service tickets are represented as tags on the contact record (e.g., 'Ticket-Open-HVAC', 'Ticket-Closed-2024Q4'). Ticket status, priority, and category map to separate tag prefixes so Mailchimp segments can filter by ticket state. The full ticket body is not preserved in Mailchimp — raw ticket data is exported as a JSON reference file.
Evatic
Asset
Mailchimp
Tags + Merge Field
1:1Equipment and asset records attached to a customer become tags on the contact (e.g., 'Asset-Type: Generator', 'Asset-Model: XYZ-5000'). Asset serial number and install date migrate as merge fields if they exist on the Evatic record. When multiple assets are present, each asset contributes its own set of tags and the serial numbers are concatenated in the merge field for completeness.
Evatic
Company / Organization
Mailchimp
Contact Company Name Field
1:1Evatic's Company or Organization object maps to the COMPANY merge field on the Mailchimp contact. If the customer is an individual without a company, the field is left blank. Mailchimp does not have a separate Company object — company-level data lives as a field on the contact.
Evatic
Technician / Employee
Mailchimp
Not Migrated
1:1Evatic technician and employee records have no Mailchimp equivalent. Internal service staff are not email‑marketing contacts, and Mailchimp's platform is designed for external audience engagement rather than internal workforce management. Consequently, we do not migrate technician objects — only customer‑facing contact records are imported into Mailchimp to preserve a clean marketing‑focused audience.
Evatic
Customer Address
Mailchimp
Contact Address Merge Fields
1:1Evatic customer address fields (street, city, state/province, postal code, country) map to Mailchimp's built‑in address merge fields (ADDR, CITY, STATE, ZIP, COUNTRY). Structured address components enable Mailchimp's geolocation segmentation, allowing you to target contacts by region or run location‑based campaign triggers without additional data processing.
Evatic
Evatic Tags / Labels
Mailchimp
Mailchimp Tags
1:1Evatic's own tag or label taxonomy maps directly to Mailchimp Tags. Tags are additive — a contact can carry multiple tags from Evatic. We preserve the original tag names and apply them at the contact level during migration. Duplicate tag names from different Evatic object types are prefixed (e.g., 'Contract:', 'Ticket:', 'Asset:').
Evatic
Unsubscribe / Marketing Consent
Mailchimp
Contact Status
1:1Evatic's marketing‑consent flag maps to Mailchimp contact status: subscribed contacts enter as 'subscribed', opted‑out contacts enter as 'unsubscribed' (preserving suppression), and pending‑confirmation contacts enter as 'pending' to trigger double opt‑in. This mapping ensures GDPR and CAN‑SPAM compliance at cutover, protecting your sender reputation and legal standing.

Evatic gotchas
Public API schema and endpoint reference is gated
DATEV integration locks fiscal data into a regional format
Managed Print Services (MPS) object hierarchy adds non-standard objects

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

Migration approach
Extract Evatic customer data via Evatic Connect
We connect to your Evatic instance via Evatic Connect (ESH) to pull all Customer, Contract, Asset, and ServiceTicket records. The export runs as a controlled file extraction with a manifest listing record counts per object. We validate the export against Evatic's API schema to catch missing fields before the mapping phase begins. Custom field metadata (field names, data types, pick-list values) is captured separately from the data export so merge field creation in Mailchimp is precise.
Audit consent fields and resolve multi-email duplicates
Before any contact is created in Mailchimp, we audit the Evatic consent field to build a value-mapping table for Mailchimp status. We also identify customers with multiple email addresses — Evatic may store work, personal, and billing emails on the same record. The primary email is designated for the Mailchimp contact; secondary emails are stored in a custom merge field. Contacts with duplicate email addresses across different Evatic customer records are flagged for your team to resolve before migration commits.
Create Mailchimp merge fields and tag taxonomy
Based on the Evatic custom field audit, we pre-create the merge fields in your Mailchimp Audience. Text, date, number, and dropdown field types are matched to Mailchimp's merge field types. We also establish the tag taxonomy — prefixes for Contract, Ticket, Asset, and Customer-Type tags are agreed upon in the migration plan so segmentation queries are clean from the start. If the merge field count exceeds Mailchimp's 80-field limit, we present the overflow strategy (JSON blob field + tag fallback) for your approval before proceeding.
Run sample migration with field-level diff
A representative slice of 200–500 Evatic contacts migrates to Mailchimp first, covering representative contract types, ticket categories, and asset types. We generate a field-level diff comparing the source Evatic values against the destination Mailchimp contact fields and tags. You verify that merge field values are correctly populated, tags are applied with the right prefixes, and consent mapping produced the expected Mailchimp status per contact. Approval of the sample unlocks the full migration.
Execute full migration with delta-pickup window
The full Evatic contact base migrates to Mailchimp via the Bulk Management API, respecting Mailchimp's rate limits to avoid throttling. A delta-pickup window of 24–48 hours after the initial run captures any new Evatic contacts or consent changes that occurred during cutover. The audit log records every upsert operation. If reconciliation reveals unexpected gaps, one-click rollback reverts the Mailchimp Audience to its pre-migration state so the issue can be diagnosed and the run re-executed.
