Migrate from Cirrus CRM to Mailchimp

Cirrus CRM Contacts migrate to Mailchimp Audience members. Email address is the dedupe key. Standard fields (first name, last name, phone, address) map to Mailchimp's address and phone merge fields. We validate every email address against Mailchimp's syntax requirements before import; invalid addresses are flagged in a separate manifest for customer review. Contacts without a valid email address cannot migrate and are excluded from the import manifest.

Cirrus CRM Company records encode into Mailchimp as a combination of merge fields and tags on the corresponding member. We create a COMPANY merge field in the Mailchimp audience and populate it from the Cirrus CRM Company name. If the customer uses Company credit information or geographic enrichment from Cirrus CRM, these map to additional custom merge fields (COMPANY_CREDIT, COMPANY_CITY, COMPANY_COUNTRY). The member's tag list is extended with a tag matching the Company name for segmentation.

Cirrus CRM Contacts carry a lookup relationship to a Company. Since Mailchimp has no native concept of Account-Contact hierarchy, we encode this relationship as a tag on the audience member (e.g., tag: CompanyName). This allows segmentation by company in Mailchimp, though it does not create a structural hierarchy. Customers needing true account-contact hierarchy in Mailchimp should evaluate Mailchimp's CRM capabilities or a complementary CRM integration.

Cirrus CRM Activity Notes attached to Contact records migrate to Mailchimp member notes. We preserve the original note body and timestamp. Note content is appended to the member's activity history in Mailchimp as a manual note entry. This is the only engagement type that has a meaningful Mailchimp analog; calls, emails, meetings, and tasks have no Mailchimp counterpart and are documented in a separate engagement inventory for the customer's admin.

Cirrus CRM Campaign records (name, objective, status) migrate to Mailchimp Campaigns as a reference inventory, not a functional migration. Mailchimp Campaigns are email campaign objects tied to specific audiences and automations; they do not carry Cirrus CRM's campaign-level financial objectives or multi-channel tracking. We map campaign name and status to Mailchimp campaign name and tag the migrated audience members accordingly for historical reference.

Cirrus CRM Owners (sales reps) referenced on Contact and Company records map to Mailchimp as a tag on each member (e.g., OWNER: [email protected]) or as an internal note if the customer prefers not to expose owner assignments in Mailchimp. Owner mapping is informational only; Mailchimp has no native owner-assignment or territory model. Customers needing rep-level attribution should configure Mailchimp's tagged campaigns or a reporting integration post-migration.

Cirrus CRM tenant-specific custom fields on Contacts require field-by-field mapping to Mailchimp merge fields. We extract the customer's field configuration (field name, type, picklist values if applicable) before migration, then create matching merge fields in the Mailchimp audience with the appropriate type (text, number, date, phone, address, dropdown). Multi-select picklist values in Cirrus CRM map to Mailchimp tags or a comma-separated text merge field based on the customer's segmentation preference.

Cirrus CRM Company custom fields (credit ratings, industry classifications, custom identifiers) map to Mailchimp merge fields on the audience using the same type-mapping logic as Contact custom fields. Company-specific custom fields are stored as member-level merge field values associated with the primary Contact that references the Company, or as audience-level tags if the customer prefers company-level segmentation over per-member field storage.
