Overview

What this migration involves

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.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Cloze

What's pushing teams away

  • Reliability problems force users to reinstall the app every few months and reset their integrations, wasting significant setup time.
  • Customer support is slow and unhelpful — the Facebook community is described as inactive and responses take days or weeks.
  • The platform is heavily hardwired toward real estate terminology and workflows, making it awkward for non-realtors working in other industries.
  • Image handling is disastrous for Mac Mail users, and the platform lacks basic navigation features like breadcrumbs to move backwards through views.
  • Poor search functionality and near-illegible threaded conversation views with tiny fonts frustrate daily users.

Choosing

Mailchimp

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How Cloze objects map to Mailchimp

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

maps to

Mailchimp

Member (Audience Contact)

1:1
Fully supported

Cloze 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

maps to

Mailchimp

Member Merge Fields + Notes

lossy
Fully supported

Mailchimp 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)

maps to

Mailchimp

No equivalent

1:1
Fully supported

Cloze'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

maps to

Mailchimp

Tags

1:many
Fully supported

Cloze 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

maps to

Mailchimp

Tags

1:1
Fully supported

Cloze 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

maps to

Mailchimp

Merge Fields

1:1
Mapping required

Cloze 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)

maps to

Mailchimp

No equivalent

1:1
Fully supported

Cloze 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

maps to

Mailchimp

Mailchimp User Roles

lossy
Mapping required

Cloze 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.

Pair-specific challenges

  • Mailchimp has no native company object

    Cloze's Company object has no direct equivalent in Mailchimp. Companies in Cloze are top-level records linked to People; Mailchimp Members have no parent Account. We resolve this by storing the company name in the COMPANY merge field and additional company properties (industry, address) as member notes. Cross-contact company reporting (e.g., all members at a given company) requires a workaround in Mailchimp — either a consistent COMPANY merge field value with segment filtering, or a note on each member. We document this gap and recommend that customers who rely on company-level reporting consider pairing Mailchimp with a lightweight CRM rather than relying on Mailchimp for account-level visibility.

  • Projects, Deals, and Pipelines do not exist in Mailchimp

    Cloze's Projects/Deals/Properties with stage pipelines have no equivalent in Mailchimp. Mailchimp is an audience and campaign platform — it does not track opportunities, deal values, or sales pipeline stages. Any business process tracked in Cloze as a Deal or Project (e.g., property listings, subscription renewals, sales opportunities) will not transfer to Mailchimp. We flag every unique project and deal record in a written inventory, noting deal name, stage, value, and close date, so the customer can track these in a separate system post-migration.

  • Suppression list must be imported before contacts

    Mailchimp charges for all contacts stored in an audience, including unsubscribed and bounced contacts under some pricing configurations. We import suppression data (unsubscribed, bounced, and cleaned contacts from Cloze) into Mailchimp before any subscribed contacts are added, to prevent sending to invalid addresses and protect deliverability. Mailchimp's Omnivore spam filter can flag accounts that import large batches without prior suppression hygiene. We recommend importing in batches under 5,000 records if the list exceeds 20,000 contacts.

  • Cloze API requires manual beta approval before extraction

    The Cloze API is not publicly available. We must email [email protected] to request access and wait for instructions. This adds a dependency outside the migration timeline — we cannot begin API-based extraction until the customer secures access. We flag this in every scoping call and fall back to CSV/Excel exports from the Cloze UI if API access is delayed. The export requires Manager or Admin permissions, so the customer must confirm the exporting user has the correct role before we begin extraction.

  • Real estate terminology bleeds into exported data

    Cloze's default terminology for Deals/Projects/Properties uses real estate language even for non-real-estate businesses. When we export custom field names, stage labels, and segment names, they may include property-specific labels ('Listing Status', 'Property Type', 'Showing Requested') that are meaningless in Mailchimp's email context. We normalize these labels during transformation, replacing hardcoded real estate terminology with generic equivalents before mapping to Mailchimp merge fields and tags.

Migration approach

Six steps for a successful Cloze to Mailchimp data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Most Cloze to Mailchimp migrations complete in one to two weeks for straightforward contact and tag migrations under 10,000 contacts. Migrations with 20,000 to 50,000 contacts, multiple audience structures, suppression list coordination, or custom field remapping extend to three to four weeks. The primary variable is not record volume but the number of distinct audiences, tag groups, and custom field types that need to be designed and reconciled.
