Overview
Moving from Fans-CRM to Mailchimp is a migration from a creator-native subscriber management tool to a mainstream email marketing platform. Fans-CRM organizes data around Fans, PPV records, Content Posts, and Subscription Tiers with no public API and no documented export format, making the initial data extraction the most uncertain step of the project. Mailchimp uses a Contacts-and-Audiences model with Tags, Segments, and Merge Fields rather than subscriber lifecycle properties, which means Fans-CRM engagement scores, lapse tracking data, and financial metrics have no native Mailchimp home. We extract whatever Fans-CRM can provide through dashboard exports, design a custom field schema in Mailchimp, import contact records in dependency order (Audience first, then Tags, then Segments), and deliver a written inventory of any data that cannot map. Message templates, chat automation, and the bundled anti-detect browser sessions do not migrate as code and are not rebuilt as part of the migration scope.

Object mapping
Each row shows how a Fans-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.
Fans-CRM
Fan / Subscriber
Mailchimp
Contact (Audience member)
1:1Fans-CRM fan and subscriber records are the primary migration object. We extract name, email address, subscription status, subscription start date, and any custom engagement properties from the Fans-CRM export file. These map to Mailchimp Contacts inside an Audience, with Fans-CRM engagement scores mapped as a numeric custom field. Subscription status from Fans-CRM (active, lapsed, churned) maps to a Mailchimp tag rather than a standard field, since Mailchimp does not have a native subscription-status property beyond the built-in subscribe/unsubscribe/cleaned state. Email address is the dedupe key for import.
Fans-CRM
Subscription Tier
Mailchimp
Merge Field (Tier Label) + Tag
1:1Fans-CRM tracks tier names, tier pricing, and fan counts per tier for each creator profile. We map tier assignments as a Mailchimp merge field (e.g., TIER_NAME) on each contact record, with the tier label as a string value. We also create a Mailchimp Tag matching each tier name so that audiences can be segmented by tier using Mailchimp's tag-based filtering. If multiple tiers exist per fan (e.g., monthly and one-time PPV tiers), we create additional merge fields or comma-separated tag assignments. Tier pricing is preserved as a separate numeric merge field if the migration scope includes it.
Fans-CRM
Engagement Metrics
Mailchimp
Numeric Custom Fields
1:1Fans-CRM stores fan-level engagement scores, chatter metrics, and interaction frequency as numerical values on the fan record. These do not map to any standard Mailchimp field. We create custom numeric fields in Mailchimp (ENGAGEMENT_SCORE, CHATTER_COUNT, LAST_ACTIVE_DATE) and import the historical values. Mailchimp does not use engagement scores for automation triggers natively, but the fields are available for segmentation in Mailchimp's Segments builder using rule conditions on numeric custom fields.
Fans-CRM
PPV Record
Mailchimp
Custom Field or Notes (documented, not migrated)
lossyPay-per-view transaction records include PPV amount, fan identifier, content reference, and timestamp. Mailchimp's Contact model does not support transactional revenue records natively. We aggregate the most recent or cumulative PPV value per fan as a numeric custom field (TOTAL_PPV or LAST_PPV_AMOUNT) if the data is available in the export. Full PPV transaction history is documented as a separate structured CSV delivered alongside the migration, which the customer's admin can connect to a revenue tracking system separately. We flag this as a data inventory item, not a live CRM migration object.
Fans-CRM
Content Post
Mailchimp
Not migrated (documented inventory)
1:1Fans-CRM content posts contain media references, PPV pricing, and performance metadata. Mailchimp has no content post or media library object; content lives as attachments within campaigns. We do not migrate content posts. We deliver a written inventory of post IDs, titles, PPV prices, and post dates in a structured CSV so the customer's admin can reference them for campaign content planning inside Mailchimp. Media files remain in Fans-CRM's storage and are not transferred as part of the migration.
Fans-CRM
Tag / Smart Folder
Mailchimp
Tag
1:1Fans-CRM uses Smart Folders and tag-based content organization. We extract the underlying tag data from the export file and import each tag as a Mailchimp Tag on the relevant contact record. Tags migrate as flat labels; folder hierarchy from Fans-CRM is not preserved because Mailchimp has no equivalent nested folder structure. Tags are used for audience segmentation in Mailchimp. The customer chooses a tag naming convention during scoping if multiple fan profiles share a single Mailchimp audience.
Fans-CRM
Message Template
Mailchimp
Not migrated (documented inventory)
1:1Fans-CRM chat assistant templates, bulk message scripts, and automated reply rules are platform-specific automation logic with no direct Mailchimp equivalent. Customer Journeys in Mailchimp use a different trigger-and-action model. We document the template structures, message flows, and variable placeholders during discovery and deliver them as a written reference so the customer's admin can rebuild them in Mailchimp's automation builder. Template content does not migrate programmatically.
Fans-CRM
Team Member (Agency)
Mailchimp
Mailchimp User or not migrated
lossyFans-CRM agency users with role-based permissions represent team member records. Mailchimp does not have a full user management object comparable to a CRM; Mailchimp accounts have account-level Users and Workspace-level Members for multi-user access, but these are not contact records. We map agency team members as Mailchimp account Users if the customer requires user-level access tracking, or we document the role assignments separately. The anti-detect browser session data associated with team member accounts does not transfer and is not migrated.

Migration approach
Discovery and export feasibility assessment
We audit the Fans-CRM account for available data: subscriber counts, engagement metric fields, subscription tier structure, tag taxonomy, PPV record availability, and team member roles. Because Fans-CRM has no API, the discovery phase includes a hands-on export feasibility check: we log into the client's Fans-CRM account, navigate the reporting and export interfaces, and confirm what file formats are available (CSV, JSON, Excel). If no export is available through the dashboard, we document the manual extraction steps required and adjust the timeline accordingly. The discovery output is a written migration scope, a confirmed export format, and a preliminary field mapping from Fans-CRM properties to Mailchimp merge fields and tags.
Export extraction and field mapping design
We extract the Fans-CRM data into a staging format (CSV or JSON depending on what the platform produces). We then design the Mailchimp Audience schema: standard merge fields (FNAME, LNAME, EMAIL, PHONE) plus custom fields for every Fans-CRM property that maps into Mailchimp (ENGAGEMENT_SCORE as numeric, TIER_NAME as text, LAPSE_DATE as date, TOTAL_PPV as numeric). We design the tag taxonomy for subscription tiers, content categories, and engagement levels. The field mapping document is reviewed and approved by the client before any Mailchimp work begins. Any data that cannot live inside Mailchimp (full PPV transaction history, content posts) is flagged as a documented inventory item with a separate data deliverable specified.
Mailchimp Audience and schema configuration
We create the Mailchimp Audience (or Audiences if the client manages multiple creator profiles and wants separate lists). We configure the custom merge fields, create the tag groups, and set up initial Segments that mirror the fan segmentation structure from Fans-CRM (active subscribers, lapsed fans, tier-based segments). If the client has multiple creator profiles under a single agency account, we discuss whether to use one audience with tags per profile or separate audiences per creator, and document the tradeoffs. We run a small test import (50 records) to validate field mapping before the full audience population.
Contact import and tag population
We import contact records into the Mailchimp Audience using Mailchimp's native CSV import tool for the initial load, with any additional custom field values populated via the Mailchimp API for precision. Tags are applied in a second pass based on the Fans-CRM tag data and subscription tier assignments. We maintain a reconciliation log of record counts, import errors, and duplicate detections. If the export file contains duplicate email addresses (common in fan management tools), we apply a dedupe rule (most recent engagement date wins) and document which records were consolidated.
Segment and automation rebuild handoff
We deliver a written automation and segmentation inventory documenting every Fans-CRM bulk message flow, lapse-reengagement campaign, and Smart Folder rule. The inventory includes the trigger logic, conditions, target audience, and a recommended Mailchimp Customer Journeys equivalent. We do not rebuild automations inside the migration scope. The customer's team uses the inventory to rebuild Customer Journeys in Mailchimp, starting with the most critical retention sequences. We support a one-week post-migration window where we resolve any contact data issues identified after the first audience sync.
Cutover and data handoff
We freeze new Fans-CRM writes during the final cutover window, run a delta import of any records modified since the initial export, and mark the Mailchimp Audience as the active contact list. We deliver the final migration report including record counts by import phase, error logs, tag taxonomy, custom field definitions, and the data inventory CSV for PPV and content data. The customer is responsible for updating any downstream integrations (e-commerce platforms, analytics tools) to point to Mailchimp. We do not provide ongoing post-migration admin support, training, or Customer Journeys rebuild as standard scope.
