Overview
Moving from Cloze to Mailchimp is a platform-category migration: you are moving from an AI-powered relationship CRM with deal pipelines and activity timelines to a purpose-built email marketing platform with no native company, deal, or engagement history object. We migrate contacts (People in Cloze) with all standard properties and custom fields into Mailchimp members, reconstruct Cloze segment and stage membership as Mailchimp tags, and store company data as member merge fields or notes since no native company object exists. We cannot migrate Projects or Deals (Mailchimp has no pipeline), Cloze Score or relationship data (Mailchimp has no CRM scoring), Timeline entries (calls, emails, meetings have no equivalent), Campaigns (Mailchimp automations are a different model), or the Cloze API beta access dependency. We deliver a written automation inventory so your team can rebuild any Cloze Campaigns in Mailchimp's Customer Journey builder post-migration.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Cloze 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.
Cloze
People
Mailchimp
Member (Audience Contact)
1:1Cloze People records map directly to Mailchimp Members within a target Audience. Standard properties — first_name, last_name, email_address, phone_number, headline, and social links — map to Mailchimp merge fields (FNAME, LNAME, EMAIL, PHONE, COMPANY, SOCIALS). Cloze Stages (Lead, Potential, Active, Inactive, Past, Lost) and Segments migrate as tags on each member so that the original stage context is preserved for future segmentation in Mailchimp. Custom fields on People map to additional merge fields in Mailchimp. The member status (subscribed, unsubscribed, pending) is determined by the Cloze contact's current email marketing consent flag.
Cloze
Companies
Mailchimp
Member Merge Fields + Notes
lossyMailchimp has no native company or account object. Company records from Cloze must be stored on the member record. We map the company name to the COMPANY merge field and store additional company fields (industry, address, social URLs) as structured notes attached to the member. For teams with multiple People linked to the same Company, each member carries the company name independently. If the customer uses Mailchimp's Enterprise tier, we can use the Company Name field (when available) and document the limitation that cross-contact company reporting is not native to Mailchimp.
Cloze
Projects (Deals/Properties)
Mailchimp
No equivalent
1:1Cloze's Projects/Deals/Properties object has no equivalent in Mailchimp. Mailchimp is an email marketing platform with no pipeline, opportunity, or deal-tracking capabilities. We do not migrate Projects or Deals. We flag every unique deal name, stage, value, and close date in a written inventory so the customer can decide whether to track these in a separate spreadsheet, a different CRM, or a Mailchimp-compatible integration (e.g., HubSpot CRM for pipeline alongside Mailchimp for email).
Cloze
Segments
Mailchimp
Tags
1:manyCloze Segments and Audiences group contacts by Stage or custom criteria. We reconstruct each segment membership as individual Mailchimp tags on the relevant member records. For example, a Cloze segment 'Active Clients — Real Estate' becomes two tags: 'Stage: Active' and 'Segment: Real Estate'. Mailchimp's tag-based segmentation supports equivalent filtering. If the customer used multiple Cloze Audiences, we consolidate into Mailchimp's recommended single audience with tag-based sub-segments, since Mailchimp bills across all audiences cumulatively and managing separate audiences can inflate costs.
Cloze
Tags
Mailchimp
Tags
1:1Cloze Tags are flat labels applied to People and Companies. We map each tag directly to a Mailchimp tag on the corresponding member. Cloze tags used for contact classification (e.g., 'vip', 'referral', 'newsletter-optin') become Mailchimp tags with the same labels. No transformation is required; the tag vocabulary transfers directly. We deduplicate any tags that differ only by casing or punctuation.
Cloze
Custom Fields
Mailchimp
Merge Fields
1:1Cloze custom fields on People (text, number, date, choice/picklist) map to Mailchimp merge fields. We create the merge field in Mailchimp (via Audience > Settings > Audience fields and *|MERGE|* tags) before import and map each contact's custom field value. Choice/picklist fields from Cloze map to Mailchimp text merge fields — the dropdown constraint is not enforced in Mailchimp but we document the original picklist values for the customer's reference. Deprecated or deleted Cloze custom fields are flagged and skipped.
Cloze
Timeline Entries (Calls, Emails, Meetings, Notes)
Mailchimp
No equivalent
1:1Cloze Timeline records capture individual call logs, email threads, meeting records, and notes tied to People or Companies. Mailchimp tracks campaign-level email engagement (opens, clicks, bounces) but not individual email threads or call logs. We do not migrate Timeline entries. The customer's admin should understand that Cloze's full communication history — the feature Cloze users cite most as valuable — will not appear in Mailchimp. If call logging or meeting notes are business-critical, the customer should consider keeping Cloze as a supplemental tool or migrating to a CRM that supports these alongside Mailchimp.
Cloze
Teams
Mailchimp
Mailchimp User Roles
lossyCloze Teams control contact access and assignment. Mailchimp's user roles (Admin, Manager, Author, Viewer) govern platform access and audience permissions but do not map to Cloze's team-based contact assignment. We preserve the team structure as a written mapping document and recommend that the customer assign Mailchimp roles based on the marketing workflow rather than the Cloze team structure, since Mailchimp permissions are platform-level rather than contact-level.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Cloze gotchas
Cloze API requires manual beta access approval
Export requires Manager or Admin role permissions
Campaigns feature gated behind Business Platinum
Real estate terminology bleeds into core objects
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Cloze access and extraction method confirmation
We verify the customer's Cloze account tier (Pro at $17/month or Business Platinum for Campaigns), confirm the exporting user's role (Manager or Administrator required for full team export), and initiate the API beta access request via [email protected] if API extraction is preferred. If API access is delayed beyond five business days, we switch to CSV/Excel exports from Settings > Import/Export using an admin account. We extract People, Companies, Segments, Tags, and Custom Fields in the first pass and validate record counts against what Cloze reports in its dashboard.
Suppression list and consent audit
We extract unsubscribed, bounced, and cleaned contacts from Cloze separately and prepare them as Mailchimp-ready suppression imports. We audit each contact's email marketing consent flag (subscribed, unsubscribed, or no consent recorded) and separate contacts into three groups: active subscribers for immediate import, pending confirmation for double opt-in re-engagement, and permanently suppressed for suppression import only. Mailchimp domain authentication (SPF and DKIM) is verified before any active contact import begins.
Audience and tag strategy design
We work with the customer to design the Mailchimp audience structure. Mailchimp recommends a single primary audience with tags for sub-segmentation rather than multiple separate audiences (billing is cumulative across audiences). We design the tag taxonomy based on Cloze Stages, Segments, and Tags — mapping each distinct value to a Mailchimp tag in the format 'Stage: Lead' or 'Segment: Newsletter'. Custom field merge fields are created in Mailchimp during this phase so the import map is complete before any records move.
Sandbox import and field reconciliation
We run a full import into a test Mailchimp audience (not the production audience) with the customer's approval. We reconcile record counts (People in, Members in, Tags applied), spot-check 25 to 50 records against the Cloze source (name spelling, email accuracy, tag assignments, company merge field), and validate that custom field values transferred correctly. Any mapping corrections (field name mismatches, encoding issues, missing merge fields) happen here before production migration begins.
Production migration in phase order
We run the production migration in this order: suppression list first (unsubscribed and bounced contacts), then active contacts with company merge fields and custom field values, then tag application across all members. We use Mailchimp's REST API with batch operations (up to 500 members per batch) and respect rate limits with exponential backoff. Each phase emits a reconciliation report showing records imported, records skipped (duplicates or invalid emails), and tags applied.
Cutover, deliverability check, and automation handoff
We verify deliverability by sending a test campaign to a small internal seed list and checking inbox placement across major providers (Gmail, Outlook, Yahoo). We deliver the written automation and campaign inventory to the customer's marketing team, noting which Cloze Campaigns (if on Business Platinum) have no direct Mailchimp equivalent and recommending Customer Journey automations as the replacement. We support a three-day hypercare window for reconciliation issues and recommend the customer monitor Mailchimp's campaign analytics for two to four weeks post-migration to establish a new baseline.
