Overview
Moving from karmaCRM to Mailchimp is a partial data migration with a significant scope adjustment: karmaCRM is a lightweight CRM that stores Contacts, Companies, Deals, Tasks, Events, and Email Campaigns; Mailchimp is an email marketing platform that manages Audiences, Subscribers, Campaigns, and Automations. The primary migration object is Contacts mapping to Subscribers with full field-level fidelity including email addresses, names, phone numbers, custom fields, tags, and subscription consent. Company records have no native Mailchimp equivalent, so business name, domain, address, and industry data flatten into Mailchimp merge fields on each Contact. Deals, Tasks, and Events have no Mailchimp analog and are excluded. karmaCRM Email Campaigns on Pro and Premium tiers migrate as campaign metadata only; the HTML templates, subject lines, send histories, and open/click statistics transfer for reference while the actual campaigns are rebuilt as Mailchimp Automations post-migration. We batch-export from karmaCRM using pagination limits, validate character encoding on all freeform text fields, and push into Mailchimp using the API with 200-request-per-minute rate limit awareness and chunked subscriber batch inserts. Attachments stored against karmaCRM records have no programmatic export path and are flagged as out of scope. The karmaCRM-to-Mailchimp OAuth integration tokens do not transfer; we document the integration configuration for your admin to re-establish post-migration.

Object mapping
Each row shows how a karmaCRM 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.
karmaCRM
Contact
Mailchimp
Subscriber
1:1karmaCRM Contacts map directly to Mailchimp Subscribers. The email address serves as the dedupe key. We transfer first name, last name, phone number, address fields, custom field values, tag associations, and subscription consent status (email opt-in and date) into Mailchimp merge fields and subscriber status. Mailchimp's subscriber status (subscribed, unsubscribed, cleaned, pending) is set based on the contact's opt-in status in karmaCRM. Any karmaCRM contact with no valid email address is excluded and reported separately.
karmaCRM
Company
Mailchimp
Contact Merge Fields
lossyMailchimp has no native company or account object. karmaCRM Company records (name, domain, industry, size, address, and custom fields) are mapped to Mailchimp merge fields attached to each Subscriber. The merge field names are derived from karmaCRM field labels. We apply company data to all Contacts in karmaCRM that have a company association, using the CONTACT_COMPANY merge field for the primary company name and additional merge fields (COMPANY_DOMAIN, COMPANY_INDUSTRY, COMPANY_SIZE) for supplementary data. Company-level tag associations are preserved as Mailchimp tags on each affected Subscriber.
karmaCRM
Email Campaign (Pro and Premium)
Mailchimp
Campaign Automation (metadata reference)
1:1karmaCRM Email Campaigns on Pro and Premium tiers carry audience name, subject line, send date, open rate, click rate, and bounce count metadata. We import this data as a reference document rather than live Mailchimp campaigns. The campaign HTML body does not migrate because Mailchimp campaigns require rebuilding through its builder with current branding and list segments. The metadata document lists each historical campaign with its performance metrics so the admin can reference past performance while configuring new Mailchimp Automations. Basic tier accounts (no email campaigns) skip this mapping.
karmaCRM
Tag
Mailchimp
Tag
1:1karmaCRM Tags applied to Contacts and Companies map directly to Mailchimp native Tags. Tags are preserved as-is on each Subscriber during migration, and Mailchimp's tag-based segmentation is available immediately after migration without reconstruction. Mailchimp's tag model is more capable than karmaCRM's flat tag list, supporting tag-based customer journey entry conditions and tag-based automation splits.
karmaCRM
Deal
Mailchimp
Contact Notes
1:1Mailchimp has no deal or opportunity object, so karmaCRM Deal records (name, value, stage, owner, and created date) are stored as a custom merge field (DEAL_VALUE) and a plain-text note on each related Contact record. Deal stage pipeline names and pipeline-to-stage mapping are documented separately for the customer's admin. This mapping is informational; deal pipeline data cannot be operationalized within Mailchimp's feature set.
karmaCRM
Task
Mailchimp
Excluded
lossykarmaCRM Tasks (assignments, due dates, priority, status) have no Mailchimp equivalent. Task records are excluded from migration. Mailchimp does not support task management features. We document task count and the list of contacts with open tasks so the admin can recreate task reminders as Mailchimp Automation triggers if needed. Calendar event records (karmaCRM Events) are similarly excluded because Mailchimp provides no calendar feature.
karmaCRM
User
Mailchimp
Subscriber (conditional)
1:manykarmaCRM User accounts (team members with roles and permissions) do not map directly to Mailchimp Subscribers because Mailchimp Subscribers are external contacts, not internal team users. If a karmaCRM User account has a valid external email address and should receive marketing emails, we migrate that User as a Subscriber with a custom merge field (IS_TEAM_MEMBER__C) flagged true. Otherwise, Users are excluded from the subscriber migration and documented separately for the customer's admin to manage team access in Mailchimp.
karmaCRM
Attachment
Mailchimp
Excluded
lossykarmaCRM Attachments linked to Contacts and Companies cannot be exported through the karmaCRM API. The platform does not expose a programmatic attachment export path in its documented endpoints or knowledge base. Attachments are flagged as out of scope with a recommendation to download files manually from the karmaCRM UI before account closure. Mailchimp supports image attachments within campaign content, not as contact-level files, so any file attachments from karmaCRM must be re-uploaded manually to Mailchimp if needed as campaign assets.

Migration approach
Discovery and scoping
We audit the karmaCRM account across tier (Free/Basic/Pro/Premium), record counts per object, active email campaigns, custom field definitions, tag taxonomy, and integration configurations. We assess the Mailchimp destination: plan tier, existing audiences, configured merge fields, and any active automations. The scoping document specifies what migrates, what is excluded, and what the admin must rebuild post-migration. We verify export permission on the karmaCRM account at this stage and request elevated access if needed.
Field mapping design
We create a field mapping document that pairs each karmaCRM field (standard and custom) to a Mailchimp subscriber field or merge field. Standard fields (email, first name, last name, phone, address) map directly. Custom fields require type conversion: karmaCRM date fields become Mailchimp text merge fields; karmaCRM multi-select checkbox fields map to Mailchimp checkboxes or interest groups; numeric karmaCRM fields use Mailchimp number merge fields where the plan supports them. Merge field names are derived from karmaCRM field labels. Unmapped fields are listed as excluded with rationale.
Sandbox migration and validation
We export a subset of records from karmaCRM (typically 50-100 contacts with varied field types and tag combinations) and import into a test Mailchimp audience. We validate that field mapping produces correct data in Mailchimp merge fields, that tag associations apply correctly, and that subscription status resolves properly for opted-in and opted-out contacts. Customer review of the sandbox output confirms mapping accuracy before production migration begins.
Production migration execution
We create or confirm the destination Mailchimp audience, then batch-export from karmaCRM using pagination sequencing with rate-limit-aware request throttling. Each batch is validated for record completeness before Mailchimp API insert. We insert subscribers in Mailchimp chunked batches per Mailchimp's subscriber import limits, applying merge field data and tag assignments per the mapping document. We monitor for import errors and reconcile record counts between source and destination.
Cutover, validation, and handoff
We run a delta export of any new karmaCRM contacts created during the migration window and import those to Mailchimp as a final step. We validate final record counts, spot-check 25-50 migrated records for data accuracy, and resolve any import errors. We deliver a migration summary document covering record counts, excluded scope, merge field inventory, and a reference sheet for rebuilding karmaCRM email campaigns as Mailchimp Automations. We do not rebuild automations as part of the migration scope.
