Overview

What this migration involves

Moving from Concord CRM to Mailchimp is a directional change: Concord CRM is a self-hosted Laravel application that organizes data around Contacts, Companies, Deals, Products, and Activities, while Mailchimp is a cloud-hosted email marketing platform that stores all subscriber data inside an Audience. There is no direct equivalent in Mailchimp for Companies, Deals, Products, Activities, pipeline stages, custom objects, or workflows. We bridge that gap by converting Concord CRM objects into Mailchimp-native constructs: Contacts map to audience members, Companies map to tags on each contact record, Deals and Products map to informational tags, and Activities map to engagement indicator tags. We import suppression lists (unsubscribed and bounced contacts) separately to maintain email compliance. Concord workflows do not migrate because they do not execute during data import and Mailchimp has no equivalent runtime automation engine tied to bulk contact operations; we deliver a written inventory of every active workflow for manual rebuild in Mailchimp Customer Journey.

Leaving

Concord CRM

What's pushing teams away

  • Support response times are slow — G2 reviewers report waiting over a week for assistance with no video tutorials available to compensate.
  • Self-hosted model requires ongoing server maintenance, security updates, and PHP/Laravel version management that many teams lack resources for.
  • No built-in migration tool or guided export — teams transferring to another CRM must manually sequence CSV exports and handle relationship mapping themselves.
  • Server scaling and performance optimization fall entirely on the customer, with no SLA guarantees or managed hosting options available.
  • Limited ecosystem compared to major SaaS CRMs — fewer integrations, no marketplace of pre-built add-ons, and community resources are sparse.

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 Concord CRM objects map to Mailchimp

Each row shows how a Concord 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.

Concord CRM

Contact

maps to

Mailchimp

Audience Member

1:1
Fully supported

Concord CRM Contacts map directly to Mailchimp audience members. Email address serves as the dedupe key. We import subscribed contacts first, then separately import unsubscribed and bounced contacts into Mailchimp's suppression list to maintain compliance and prevent accidental re-subscription. Concord's email opt-in status, phone number, physical address, and custom fields map to Mailchimp merge fields (EMAIL, FNAME, LNAME, PHONE, ADDRESS) or custom merge fields if the field type is supported. Contacts exceeding Mailchimp's Free plan limit of 500 contacts are flagged during scoping and the customer selects the appropriate paid plan before migration begins.

Concord CRM

Company

maps to

Mailchimp

Tag on Contact

lossy
Fully supported

Concord CRM Companies have no direct Mailchimp equivalent because Mailchimp has no Company or Account object. We convert each Company into a tag applied to every Contact associated with it in Concord. The tag format is 'Company: [Company Name]' and preserves the company-contact relationship as a contact attribute. Company address, domain, and industry fields cannot be stored natively in Mailchimp; we map address to a merge field and store domain and industry as additional tags (e.g., 'Industry: Technology') or in a custom text merge field. Companies must be exported from Concord before Contacts so that the company-contact association is resolved during the Contact tagging step.

Concord CRM

Deal

maps to

Mailchimp

Tag on Contact

lossy
Fully supported

Concord CRM Deals have no direct Mailchimp equivalent. We convert Deal data into tags on the associated Contact record to preserve deal context. Tags include 'Deal: [Deal Name]', 'Deal Value: [Amount]', 'Deal Stage: [Stage Name]', 'Expected Close: [Date]', and 'Deal Owner: [Owner Email]'. These tags are informational only and do not create Mailchimp CRM records. Pipeline stages from Concord's multiple-pipeline model become tags under the 'Pipeline: [Pipeline Name]' prefix. The customer should select a CRM with native Deal support if ongoing deal pipeline management is required post-migration.

Concord CRM

Product

maps to

Mailchimp

Tag on Contact

lossy
Fully supported

Concord CRM Products (name, price, SKU, description) have no direct Mailchimp equivalent. We tag contacts associated with a product purchase or interest using 'Product: [Product Name]', 'Product SKU: [SKU]', and 'Product Price: [Price]' tags on the contact record. Product information preserved as tags allows the customer to segment audiences in Mailchimp by product interest or purchase history for targeted campaigns. Products that are not linked to contacts in Concord are exported as a separate reference table that the customer can use to build Mailchimp product-based segments manually.

Concord CRM

Activity

maps to

Mailchimp

Tag on Contact

lossy
Fully supported

Concord CRM Activities (calls, meetings, tasks) have no native Mailchimp equivalent. We encode engagement history as tags on each Contact record using 'Activity: Call', 'Activity: Meeting', 'Activity: Task', plus the date and a brief note summary. The most recent activity per type is stored; full activity history is collapsed into the tag set because Mailchimp does not maintain a contact activity timeline. Concord's activity-linked resource type (Contact, Company, or Deal) is preserved as an additional tag for audit purposes. The customer should understand that Mailchimp's reporting shows campaign-level engagement (opens, clicks) but not pre-campaign sales activity history.

Concord CRM

Custom Fields

maps to

Mailchimp

Merge Field or Tag

lossy
Mapping required

Concord CRM custom fields map to Mailchimp merge fields where types are compatible. Mailchimp supports TEXT, NUMBER, DATE, ADDRESS, PHONE, and WEBSITE merge field types natively. Boolean, select, and multi-select custom fields from Concord that do not map to a native Mailchimp type are converted to tags using 'Custom: [Field Name]: [Value]' format. Boolean fields produce a tag only if the value is true, omitting the tag for false values to keep the tag set lean. We confirm all Concord custom field names and types during scoping to design the merge field schema before production migration.

Concord CRM

Workflow

maps to

Mailchimp

Customer Journey Builder (manual rebuild)

1:1
Fully supported

Concord CRM workflows (trigger: Company/Contact/Deal created, Deal stage changed; action: Create Activity, Send Email, Trigger Webhook) do not migrate and do not execute during data import. Mailchimp has no equivalent runtime automation engine tied to bulk contact operations. We deliver a written inventory of every active Concord workflow during scoping, including its trigger conditions, actions, and recommended Mailchimp Customer Journey equivalent for the customer's admin to rebuild post-migration. Email-send and contact-tagging automations transfer conceptually to Customer Journey; action-type automations (Create Activity, Trigger Webhook) have no Mailchimp equivalent and require a separate tooling decision.

Concord CRM

Users and Roles

maps to

Mailchimp

Merge Field or Tag

1:1
Mapping required

Concord CRM Users (email, name, role) export via API. There is no Mailchimp equivalent for users or roles. We map the Concord user assigned as the contact owner to a 'Owner: [User Email]' tag or merge field on each Contact record, preserving the ownership attribution. Concord role names are stored as a 'User Role: [Role Name]' tag on contacts owned by users in that role. The customer's Mailchimp account admin is the only Mailchimp-level user role; shared access requires a separate Mailchimp team invitation handled outside the migration scope.

Pair-specific challenges

  • Concord workflows do not fire during data import

    Concord CRM explicitly documents that workflow actions do not execute during data import. Any automation configured to create an Activity, send an Email, or trigger a Webhook on Contact, Company, or Deal creation will not run when we import your records into Mailchimp. We flag all active workflow configurations during scoping and provide a documented inventory with recommended Mailchimp Customer Journey equivalents. The customer's admin rebuilds each workflow manually in Mailchimp post-migration. This is a structural limitation of Concord's Laravel-based automation engine, not a migration tooling gap.

  • Mailchimp Free plan caps at 500 contacts

    Mailchimp's Free plan limits the audience to 500 contacts. Concord CRM stores all contacts regardless of subscription status, including bounced and unsubscribed records. We flag the total contact count during scoping and confirm the customer's Mailchimp plan selection before migration begins. Audiences exceeding 500 contacts require an Essentials plan ($13/month) or higher. Exceeding the contact limit on the Free plan prevents additional imports and blocks campaign sends until the account is upgraded.

  • Unsubscribed and bounced contacts require separate suppression list import

    Concord CRM stores contacts, unsubscribes, and bounces in separate data tables. Importing unsubscribed or bounced contacts as active Mailchimp subscribers creates compliance violations, increases complaint rates, and risks inbox deliverability. We export the three contact states separately from Concord, import subscribed contacts as active Mailchimp audience members, and import the unsubscribe and bounce lists into Mailchimp's suppression list. Mailchimp automatically holds suppressed contacts from any campaign send. The import order matters: suppression list first, then active contacts.

  • Company and Deal associations become tags only

    Concord CRM's full data model (Companies, Deals, Products, Activities, pipeline stages, custom objects) has no native Mailchimp equivalents. These objects cannot be represented as standalone records in Mailchimp. We convert them to tags on each Contact record. Tags allow segmentation by company, deal stage, product ownership, and activity type, but they do not replace a CRM. If the customer requires ongoing deal pipeline management, product catalog tracking, or sales activity logging after migration, Mailchimp alone will not support those use cases without third-party integrations or a supplemental CRM.

  • Concord export feature requires role permission

    Concord CRM's CSV/XLS/XLSX export is gated by role-based access control. Non-admin users cannot export by default. We confirm export permissions during scoping and request that the customer assign the export permission to the API user or an admin user before migration begins. Without this permission, the UI-based export is blocked and we must use the REST API with Bearer token authentication, which paginates at 15 records by default with a maximum of 100 per_page. API pagination requires sequential page iteration with rate limit monitoring to avoid 429 errors on large datasets.

Migration approach

Six steps for a successful Concord CRM to Mailchimp data migration

  1. Discovery and scoping

    We audit the Concord CRM instance to count Contacts, Companies, Deals, Products, and Activities, identify custom field names and types, and document all active workflow configurations. We confirm export permissions and confirm the Mailchimp account plan. We identify the total contact count, the split between subscribed, unsubscribed, and bounced contacts, and the company-contact relationship density. The discovery output is a written migration scope with contact count, tag schema design, suppression list count, and timeline estimate.

  2. Mailchimp schema design and suppression list setup

    We design the Mailchimp audience schema: we create or confirm the destination audience, configure merge fields for Concord's standard and custom fields that map to Mailchimp field types (FNAME, LNAME, EMAIL, PHONE, ADDRESS, and any compatible custom merge fields), and design the tag taxonomy for Companies, Deals, Products, Activities, pipeline stages, and custom fields. We import the Concord unsubscribed and bounced contact list into Mailchimp's suppression list before any active contact import begins. This step prevents compliance violations and ensures suppressed addresses are held from campaign sends from the first day of the new audience.

  3. Test import and mapping validation

    We run a test migration using a sample of 50-100 Concord Contacts into a Mailchimp test audience or sandbox environment. We validate that tags render correctly, merge field data populates, company tags appear on the right contacts, and unsubscribed contacts are correctly excluded. We reconcile the test audience against the Concord source export and correct any field mapping or tag format issues before the production migration. This step catches problems at zero cost to the customer.

  4. Production migration

    We run the production migration in three phases. First, we import the suppression list of unsubscribed and bounced contacts from Concord. Second, we export Companies and Contacts from Concord via CSV or API, tag each Contact with its associated company, deal, product, and activity tags, and import active contacts into the Mailchimp audience using batch chunking within Mailchimp's rate limits. Third, we import a supplemental activity summary tag set for contacts with dense engagement history. Each phase emits a row-count reconciliation report showing imported count, skipped count, and error count.

  5. Cutover, validation, and handoff

    We validate the Mailchimp audience by spot-checking 25-50 contacts against the Concord source export, confirming tag accuracy, merge field completeness, and suppression list integrity. We deliver the written workflow inventory documenting every active Concord workflow with its trigger, conditions, actions, and recommended Mailchimp Customer Journey equivalent. We do not rebuild workflows as part of the migration scope. We offer a short post-migration support window to resolve any reconciliation discrepancies within the first week after cutover.
