Overview
SwiftCRM is a lightweight CRM organizing Contacts with Appointments, E-Docs, Reminders, and relationship structures. Mailchimp is an email marketing platform organizing Audiences around Members with Tags, Segments, Campaigns, and Automations. The migration is a CRM-to-email-platform move: we map SwiftCRM Contacts to Mailchimp Members (1:1 by email), carry appointment timestamps as merge fields, store relationship types as Tags, and flag all appointment, reminder, and attachment data that cannot map natively into Mailchimp. The absence of a public SwiftCRM API requires alternative extraction during discovery. SwiftCRM beta status means we freeze schema mapping against a validation snapshot near migration day. We do not migrate workflows, automations, email sequences, forms, or reports; these require manual rebuild in Mailchimp and are inventoried separately.
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 SwiftCRM 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.
SwiftCRM
Contact
Mailchimp
Member
1:1SwiftCRM Contacts with name, email, phone, and relationship type map directly to Mailchimp Members by email address as the dedupe key. The SwiftCRM Face ID protection flag is not carried to Mailchimp as there is no corresponding field; we note it as an informational property for the customer's records. Any Contact without a valid email address is held in a reconciliation queue for manual resolution before import because Mailchimp requires an email address for Member creation.
SwiftCRM
Appointment
Mailchimp
Merge Fields + Tags
lossySwiftCRM Appointments with scheduled dates, times, and client links cannot map to any native Mailchimp object because Mailchimp is not a scheduling or CRM platform. We carry appointment date and time as mm_appointment_date and mm_appointment_time merge fields on the Member record, and add a mm_has_appointment tag for audience segmentation. The customer rebuilds any appointment reminder workflow as a Mailchimp automation post-migration.
SwiftCRM
Reminder
Mailchimp
Merge Fields + Tags
lossySwiftCRM Reminders tied to clients or appointments cannot import into Mailchimp's activity model. We map reminder dates to mm_reminder_date merge fields and flag mm_reminder_set tags on Member records. Notification history is mapped to mm_notification_history tags. The customer configures their own reminder cadence in Mailchimp automations post-migration.
SwiftCRM
E-Docs
Mailchimp
Documentation Inventory
1:1SwiftCRM E-Docs are not importable into Mailchimp, which has no native file attachment model for Member records. We export all attached files and produce a CSV inventory listing each file name, the linked Contact email address, and a location reference. The customer redistributes files manually, links them via a cloud storage URL in a custom merge field, or uses an alternative document management tool post-migration.
SwiftCRM
Custom Fields
Mailchimp
Merge Fields
lossySwiftCRM custom fields vary by account tier during beta. We audit all available custom fields during scoping and map them to Mailchimp merge fields, subject to the 30-field limit on free and Essentials plans and the 80-field limit on Mailchimp Premium. Fields exceeding the limit are stored as mm_custom_tag tags or flagged for manual post-migration entry on the Member record.
SwiftCRM
Relationships
Mailchimp
Tags
lossySwiftCRM family and business relationship structures between Contacts do not have a native Mailchimp equivalent. We map relationship type to mm_relationship_type tags on the Member record (e.g., family_member, business_client, referral_partner). When both related Contacts are present in the Mailchimp audience, we store the related Contact email as mm_related_contact_email for reference. The customer rebuilds any relationship-dependent segmentation as Mailchimp segments post-migration.
SwiftCRM
Users
Mailchimp
Mailchimp Seat (manual)
lossySwiftCRM User accounts and permissions cannot map to Mailchimp seat access because the two platforms manage user roles differently and Mailchimp seats do not correspond to CRM ownership hierarchies. We produce a User inventory document mapping SwiftCRM users to the Mailchimp accounts they should access, and the customer provisions Mailchimp seats manually post-migration.
SwiftCRM
Notifications
Mailchimp
Tags
lossyNotification history tied to client interactions in SwiftCRM migrates as mm_notification_history tags on the Member record. The notification content (message text, timestamp, delivery status) is not transferable to Mailchimp's engagement model. We note the notification count as mm_notification_count for the customer's reference in segmentation.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
SwiftCRM gotchas
No public API documentation requires manual or alternative export
Active beta status means schema may change during migration
Pricing tiers are not publicly documented
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
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Discovery and export feasibility
We audit SwiftCRM objects in scope: Contacts, Appointments, E-Docs, Reminders, Notifications, Relationships, custom fields, and Users. Because SwiftCRM has no public API, we confirm what export options are available (data dump, CSV, direct access) during scoping before committing to timelines. We assess email validity across Contacts, identify duplicate records, and inventory the full set of custom fields and relationship types that need merge field or tag allocation in Mailchimp.
Mailchimp schema setup
We configure the destination Mailchimp audience: audience name, domain authentication, default unsubscribe settings, and required compliance fields. We create merge fields for every mappable SwiftCRM property (first name, last name, phone, appointment date, reminder date, relationship type, and custom fields) within the 30-field free/Essentials or 80-field Premium limit. We design the tag taxonomy for relationship types, notification flags, and appointment markers, and configure merge field character limits to flag any truncation before import begins.
Data extraction from SwiftCRM
We extract data using the confirmed export method. For CSV exports, we validate column headers against the scoping schema and flag any missing or malformed fields. For manual exports, we provide a structured template and validate the output before transformation begins. We take a schema snapshot at extraction time to lock the field mapping against SwiftCRM's current beta schema.
Transformation and data quality
We deduplicate Contacts by email address, validate email formats, and resolve any Contacts without valid email addresses to a manual-reconciliation queue. We truncate long free-text fields to 254 characters and flag them as truncated in the migration report. Appointment dates and times map to merge fields and tags. Relationship types map to tags. E-Docs are exported as a file inventory with contact-email linkage for the customer to redistribute. Custom fields are mapped within the merge field budget or flagged for tag storage.
Mailchimp import and reconciliation
We import Contacts into the Mailchimp audience in batches via the Mailchimp API with rate-limit handling. We reconcile row counts (Contacts exported, Members imported, failures), spot-check 25-50 Member records against the SwiftCRM source, verify email addresses are present on all imported Members, and flag any records that failed import with the reason code. We validate that Tags were applied correctly and that merge field values match the SwiftCRM source data within truncation limits.
Deliverables handoff and admin rebuild inventory
We deliver the final reconciliation report, the E-Docs file inventory CSV, the tag taxonomy reference, and the merge field mapping document. We deliver a written inventory of any automations, forms, or scheduling workflows that cannot migrate and require rebuild in Mailchimp. We do not rebuild automations or configure Mailchimp automations as standard scope; that work is the customer's admin task or a separate engagement. We support a three-day post-migration window to resolve import failures raised by the customer's team.
