Migrate from Gearbox to Mailchimp

Gearbox contacts map directly to Mailchimp subscribers on a one-to-one basis. Standard contact properties including name, email, phone, and address map to Mailchimp's default merge fields. Custom contact properties from Gearbox require the creation of custom merge fields in Mailchimp to preserve those values during migration.

Mailchimp has no native companies object, so Gearbox company properties are stored as merge fields on the primary subscriber contact. Company properties including name, domain, industry, employee count, and annual revenue are mapped to custom merge fields on the primary contact record. Company hierarchy relationships in Gearbox collapse to the primary contact's merge fields.

Gearbox deals have no native Mailchimp equivalent, so deal data is encoded into Mailchimp subscriber tags using a structured format. Deal name, pipeline name, stage name, amount, and close date are encoded as Mailchimp subscriber tags with the format Pipeline_Name: Deal_Name — Stage: StageName. Deal amounts are stored separately as a custom Deal_Amount__c merge field to preserve monetary values.

Gearbox pipelines are encoded as tag prefixes in Mailchimp, creating distinct namespaces for each pipeline. Each Gearbox pipeline name becomes a tag namespace so subscribers with deals in multiple pipelines can be segmented by pipeline origin using tag filters. This enables multi-pipeline agencies to maintain visibility into deal origins within Mailchimp's tag-based segmentation.

Gearbox stage names within a pipeline are mapped to tag suffixes appended to the pipeline tag. Stage values are preserved verbatim in the tag string without transformation. Stage-entered timestamps are stored as custom datetime merge fields on the subscriber record for reporting continuity and historical tracking.

Mailchimp has no native lifecycle stage concept, requiring a custom solution. Gearbox lifecyclestage values are preserved as a custom pick-list merge field called Lifecycle_Stage__c on each subscriber. Valid Gearbox values include subscriber, lead, MQL, SQL, Customer, and Evangelist. The pick-list values are created in Mailchimp to match Gearbox exactly.

Gearbox email engagement activity including opens, clicks, and sends are recorded as engagement tags on the subscriber record. Tags use a format such as Opened_Campaign_Name or Clicked_Campaign_Name. Original engagement timestamps and campaign names are preserved as custom datetime merge fields on each subscriber for historical reporting.

Mailchimp has no native call or SMS activity log functionality, requiring custom field storage. Gearbox call notes are stored as a custom text merge field named Gearbox_Call_Notes__c on the subscriber record. SMS send logs are stored as Gearbox_SMS_Log__c. These custom fields serve as reference-only archives and do not trigger Mailchimp automations.

Gearbox custom contact and company properties map to Mailchimp custom merge fields. Field data types are preserved during migration: text fields remain text, numeric fields remain number, date fields remain date, and pick-list values become pick-list merge fields. Mailchimp Premium supports up to 80 merge fields total, while standard plans have lower limits.

Gearbox subscriber tags migrate to Mailchimp tags one-to-one with no transformation. Tags are applied during the migration run. Gearbox tag taxonomy hierarchies flatten into a single tag namespace in Mailchimp. Dynamic segmentation rules and complex tag-based segments built in Gearbox require manual recreation in Mailchimp's segment builder after migration.

Gearbox workflow automations use a trigger-action-condition engine that does not export. Mailchimp Customer Journeys use a different event-based automation model. Every Gearbox workflow must be rebuilt manually in Mailchimp after migration. FlitStack exports Gearbox workflow definitions as a rebuild reference document.

Gearbox includes two-way SMS and web chat as native platform features alongside email campaigns. Mailchimp is primarily an email-focused platform. SMS functionality in Mailchimp requires a separate paid add-on available in higher-tier plans with its own configuration workflow. Web chat and two-way conversational messaging features have no Mailchimp equivalent.

Gearbox owner email addresses are matched to Mailchimp subscriber email addresses for attribution purposes. Owner names are stored as a custom merge field named Gearbox_Owner__c on the subscriber for reference. Owner assignment in Gearbox does not create corresponding Mailchimp team member records — the relationship is preserved as a data field only.

Gearbox includes review-request and reputation management tools as built-in features. Mailchimp has no built-in reputation management module for soliciting, tracking, or managing third-party reviews from customers. This feature must be sourced from a dedicated reputation management tool and integrated separately after migration is complete.
