Overview
Rubi CRM and Mailchimp occupy different roles in a business stack. Rubi CRM is a record-based CRM built for membership organisations, training providers, and events companies with native UK accounting integrations and an Outlook email plugin. Mailchimp is a contact-centric email marketing platform with audience segmentation, automation, and basic CRM capabilities but no native pipeline management, task tracking, or event-booking module. The migration maps Rubi CRM's Contacts and Members to Mailchimp Contacts with subscription-status flags, stores membership tier and renewal dates as Mailchimp Merge Fields, and carries forward event registration as audience Tags or segments. We do not migrate Sales Pipeline stages, Tasks, Saved Reports, or Audit Logs because these have no equivalent in Mailchimp's data model. Rubi CRM's native Mailchimp integration suggests historical data is likely already partially synced; we validate the integration endpoint during scoping and handle any delta records.

Object mapping
Each row shows how a Rubi CRM 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.
Rubi CRM
Contact
Mailchimp
Contact (Mailchimp Audience Member)
1:1Rubi CRM Contacts migrate to Mailchimp Contacts as primary subscriber records. Email address is the dedupe key. First name, last name, phone, and address fields map to standard Mailchimp merge fields (FNAME, LNAME, PHONE, ADDRESS). Any custom contact properties in Rubi CRM require a pre-migration schema audit because Rubi CRM does not expose a public schema endpoint—we discover field names during the export scoping phase and create matching Mailchimp merge fields before import. Subscription status (subscribed, unsubscribed, cleaned) must be kept in separate import categories per Mailchimp compliance guidance to avoid bounces and abuse complaints.
Rubi CRM
Member
Mailchimp
Contact (Mailchimp Audience Member)
1:1Rubi CRM Member records are distinct from Contacts and tied to the membership module. We map Member ID and membership status fields but treat Members as primary subscriber records if they overlap with or supersede Contact records (common in membership-organisation data models where Members and Contacts share the same email). The mapping uses email as the deduplication key, pulling the most recent membership status per email address when both a Contact and a Member record exist for the same address.
Rubi CRM
Membership
Mailchimp
Merge Fields (Tier, Status, Renewal Date)
lossyRubi CRM Membership records store tier names, status (Active, Lapsed, Cancelled), start dates, and end dates. We map these to Mailchimp Merge Fields: a tier text field, a status dropdown-style field, and date fields for renewal. Rubi CRM does not export full subscription history in a single pass—we note this during scoping and recommend a separate export run from the Membership module if historical tier changes are required. Mailchimp's merge field documentation confirms this is the correct approach when the CRM has a data field the audience does not natively support.
Rubi CRM
Company
Mailchimp
Merge Field (Company Name)
lossyRubi CRM Company records hold business-level data and relate to Contacts. Mailchimp has no Company or Account object, so we store the company name in a COMPANY merge field on each Contact. The Company-to-Contact relationship is resolved during import by matching the company name or domain against the Contact record's email domain or a mapped company field. This is a flattened representation—Mailchimp cannot replicate the relational Company-Contact hierarchy that Rubi CRM provides.
Rubi CRM
Events and Training
Mailchimp
Tags and Audience Segments
1:manyRubi CRM Events and Training bookings are child records tied to Contacts or Members. We map event name, date, and booking status as Mailchimp Tags (e.g., TAG: 2025-Annual-Conference-Attended, TAG: Training-Booking-Completed). For recurring events or series, we create audience segments based on tag combinations (attended X or Y event type). Seat-level attendance data requires a separate export from the Events module and is imported as additional tags or segment criteria. Mailchimp does not have a native event management object—this tag-based representation is the closest structural equivalent.
Rubi CRM
Activity (Email)
Mailchimp
Contact Tags and Activity Note
1:1Rubi CRM email interactions logged via the Outlook plugin are stored as Activities linked to Contacts. Mailchimp tracks email engagement passively (opens, clicks, unsubscribes) but has no activity history object for pre-migration email logs. We import email engagement history as Contact Tags indicating the last contact date or a high-level engagement category (e.g., TAG: Email-Active-2024). Thread-level threading and email body content do not migrate because Mailchimp has no object to store them.
Rubi CRM
Sales Pipeline
Mailchimp
N/A
1:1Rubi CRM Sales Pipelines use a Kanban-style view with user-defined stage names stored as custom fields against deal records. Mailchimp has no pipeline, opportunity, or deal-tracking object. Stage names, deal values, and pipeline status do not migrate. We document the existing pipeline structure and stage names in the handoff inventory so the customer's team can recreate any relevant segmentation logic as Mailchimp audience segments or tags.
Rubi CRM
Task
Mailchimp
N/A
1:1Rubi CRM Tasks are standard records with owner, due date, and status. Mailchimp has no task or to-do management. Task records do not migrate. We export the task list as a CSV inventory and deliver it as part of the handoff documentation so the customer's team can recreate priority follow-ups in Mailchimp automation triggers or an external task tool.

Migration approach
Scoped export and Mailchimp pre-audit
We coordinate with the customer's Rubi CRM team to extract Contacts, Members, Memberships, Companies, Events, and Activity records from the platform. We request read-only admin access or a direct export file from Rubi CRM support given the undocumented API. In parallel, we audit the destination Mailchimp audience for existing contacts, tags, merge fields, and any records created by the native Rubi CRM-Mailchimp integration. We identify duplicate email addresses and flag the dedupe strategy before any import begins.
Data cleansing and normalization
We run a data quality pass on the exported Rubi CRM records: duplicate email addresses are merged or flagged, permanently bounced emails are excluded, contacts with no email address are noted as non-importable, and membership tier names are normalized to a consistent set of values. We split the cleaned dataset into subscribed, unsubscribed, and cleaned import categories per Mailchimp compliance guidance. This pass also identifies any Rubi CRM custom fields not visible in standard exports and requests a supplementary custom-field export from Rubi CRM admin.
Mailchimp merge field and tag schema creation
We create the Mailchimp merge fields required to hold Rubi CRM data: COMPANY for company name, MEMBERID for Rubi CRM Member ID, MEMBTIER for membership tier, MEMBSTATUS for membership status, MEMBSTART and MEMBEND for membership start and end dates, and any custom fields discovered during scoping. We also define the tag taxonomy for event attendance and activity history. Merge fields are created in the Mailchimp audience before any contacts are imported to avoid partial-data records.
Contact and Member import with dedupe
We import Rubi CRM Contacts and Members into Mailchimp using the cleaned and split import files. Email address is the dedupe key. Where a Contact and a Member share the same email address, we consolidate to a single Mailchimp contact, pulling the most recent membership status and the Contact's full name and address. Each contact receives its merge field values at import time. Subscription status is set from the Rubi CRM contact status field.
Membership data, event tagging, and segment creation
We update merge field values (membership tier, status, start date, end date) for all contacts that have a corresponding Rubi CRM Membership record. Event attendance tags are applied to contacts based on the Events and Training export, creating a tag per event type or per individual event. We create Mailchimp audience segments for each membership tier, active versus lapsed status, and event-attendance combinations so the customer's team can trigger automated journeys immediately after migration.
Cutover, validation, and handoff documentation
We run a final reconciliation comparing Rubi CRM record counts against Mailchimp contact counts, merge field population rates, and tag assignment rates. We validate a sample of 25-50 records against the Rubi CRM source. We deliver the Pipeline and Task inventory CSV, the Workflow and Automation rebuild handoff note, and the merge field mapping document. We do not rebuild automations in Mailchimp; we document the recommended trigger conditions and journey logic so the customer's marketing team can implement them post-migration.
