Overview
Berry CRM and Mailchimp serve fundamentally different functions, which makes this migration a platform-type shift, not a like-for-like CRM swap. Berry CRM is an all-in-one CRM for small teams managing Contacts, Companies, Deals, Invoices, Projects, and Tasks. Mailchimp is an email marketing and marketing automation platform whose core data model is the Audience (contacts with email addresses), supplemented by Tags, Groups, Segments, Campaigns, and Automations. We migrate what Mailchimp can hold: contact records with email, name, phone, address, and any structured custom fields from Berry CRM. We do not migrate Deals, Companies, Invoices, Projects, or Tasks because Mailchimp has no equivalent CRM object model. We extract data through Berry CRM's available export path, clean records for Mailchimp compliance (removing bounced contacts, preserving unsubscribe flags), and deliver a written inventory of any Berry CRM automation or workflow requiring rebuild in Mailchimp's automation 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 Berry 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.
Berry crm
Contact
Mailchimp
Audience Member
1:1Berry CRM Contacts migrate to Mailchimp Audience Members. The email address serves as the dedupe key and is required; any Berry CRM contact without a valid email address cannot migrate to Mailchimp and is flagged in a separate exclusion report. First name, last name, phone, address, and any structured custom field values migrate to Mailchimp merge fields (FNAME, LNAME, PHONE, ADDRESS, and custom MERGE tags). We preserve the original Berry CRM contact ID in a note field for audit traceability.
Berry crm
Company
Mailchimp
None (no equivalent)
lossyBerry CRM Company records do not have a direct Mailchimp equivalent. Mailchimp does not have an Account or Organization object at the CRM level. We extract Company names and domain data during scoping and offer two paths: store company name as a Mailchimp merge field on each Contact, or deliver company-contact mapping as a separate CSV for the customer's reference if they later integrate Mailchimp with a CRM that supports Company objects.
Berry crm
Deal
Mailchimp
None (no equivalent)
lossyBerry CRM Deals (pipeline stages, amounts, close dates) have no Mailchimp equivalent. Mailchimp's audience model does not include Opportunity or Deal records. We extract Deal data during scoping and deliver it as a written CSV inventory keyed by contact email, so the customer's admin can optionally import deal-stage information into a separate spreadsheet or a CRM that supports pipeline tracking. If the customer is moving entirely to Mailchimp for marketing, we note that pipeline management requires a separate tool.
Berry crm
Sales Quote
Mailchimp
None (no equivalent)
lossyBerry CRM Sales Quotes and their line items, pricing, and status do not migrate to Mailchimp. Mailchimp has no quoting or proposal object. We extract quote data as a written CSV inventory for the customer's records, noting that any future quoting needs a dedicated CRM or quoting tool integrated with Mailchimp.
Berry crm
Product
Mailchimp
None (no equivalent)
lossyBerry CRM Products and Price Books do not have a Mailchimp equivalent. Mailchimp supports product connections through its E-Commerce integration (available on Standard and Premium tiers with Shopify, WooCommerce, BigCommerce, or Magento), but Berry CRM's product catalog does not export in a compatible format. We deliver product data as a written CSV for reference and note that a future e-commerce integration would require manual product entry in Mailchimp or a connected store.
Berry crm
Invoice
Mailchimp
None (no equivalent)
lossyBerry CRM Invoices (line items, totals, payment status, contact associations) have no Mailchimp equivalent. Mailchimp is an email marketing platform, not a billing system. We extract invoice data as a written CSV inventory keyed by contact email for the customer's records. Any future invoice history requires a dedicated billing or accounting tool.
Berry crm
Project
Mailchimp
None (no equivalent)
lossyBerry CRM Projects and associated task data do not migrate to Mailchimp. Mailchimp has no project management or task tracking capability. Project metadata is extracted as a written inventory if relevant, but no equivalent destination exists in Mailchimp.
Berry crm
Task
Mailchimp
None (no equivalent)
lossyBerry CRM Tasks (titles, due dates, assignees, completion status) linked to contacts or deals do not migrate to Mailchimp. Mailchimp's Customer Journey automations can trigger based on contact actions (email opens, link clicks, tag changes) but do not create task records assigned to team members. Task data is delivered as a written inventory if the customer needs it for future CRM selection.
Berry crm
Custom Fields
Mailchimp
Merge Fields
lossyBerry CRM allows custom fields on primary objects but the mechanism is not publicly documented. We detect custom fields during data extraction and map each to a corresponding Mailchimp merge field (MERGE1 through MERGE8 on the Free/Essentials tier, unlimited on Standard and Premium). Merge field types in Mailchimp are text, number, date, phone, address, or URL. We map Berry CRM custom field types to the closest Mailchimp merge field type and flag any that cannot be represented.

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.
Berry crm gotchas
Very limited public documentation and schema
Single review on G2 with no peer data
Website URL contains a typo in domain
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
Discovery and data audit
We run a discovery export from Berry CRM to map the actual data structure. Given the limited public documentation, this step involves direct data exploration to identify all object types, custom fields, and relationship patterns present in the customer's instance. We count contacts (with and without email addresses), companies, deals, tasks, invoices, and any other records present. We also identify unsubscribe flags, bounce history, and tag or segment structures in Berry CRM that could map to Mailchimp tags or groups.
Audience design and merge field mapping
We design the Mailchimp audience structure before migration. This includes defining which merge fields (FNAME, LNAME, PHONE, ADDRESS, and custom MERGE tags) correspond to Berry CRM contact fields and custom fields. We confirm the Mailchimp plan tier (Free, Essentials, Standard, or Premium) because merge field limits vary. We create the Mailchimp audience and apply any initial tag or group taxonomy the customer wants to use for segmentation. Suppression list import (for unsubscribed and bounced contacts) happens before the active contact migration.
Contact extraction, cleaning, and transform
We extract contact records from Berry CRM, apply a cleaning pass (standardize phone number formats, fix incomplete addresses, remove duplicates based on email address), and transform field values to match Mailchimp merge field requirements. Contacts without email addresses are excluded and added to the exclusion report. We validate that all required Mailchimp merge field types (text, number, date, phone, address, URL) are supported before import.
Migration and validation
We import contacts into the Mailchimp audience using the platform's standard import path. After import, we run a reconciliation pass comparing the Berry CRM contact count and email list against the Mailchimp audience member count. We spot-check 20-30 records for field-level accuracy and confirm that unsubscribe and bounce suppression lists are populated correctly. Any mapping corrections are made and a delta re-import is run if needed.
Delivery and automation rebuild inventory
We deliver the final migration report including contact counts, exclusion counts (contacts without email), suppression list count, and any custom field mapping notes. We deliver a written inventory of Berry CRM workflows, automations, or task reminders that do not have a Mailchimp equivalent. The customer's admin uses this inventory to rebuild any desired automation in Mailchimp's Customer Journey builder. We do not rebuild automations as code inside the migration scope.
