Overview
Moving from ActiveCampaign to Mailchimp is a data-reduction migration in two senses: you are moving to a simpler platform and you are losing features. Mailchimp has no equivalent to ActiveCampaign's Deals, Pipelines, Accounts, or Automations. We migrate Contacts (with full field-level mapping including custom fields), Tags, and suppression lists. We do not migrate Deals, Pipeline stages, Account records, Automations, Forms, or Landing Pages as Mailchimp's object model does not support these concepts at the same level of depth. We deliver a written automation inventory for your team to rebuild in Mailchimp's Customer Journey Builder. ActiveCampaign's contact-based pricing counts all statuses including unsubscribes; archiving suppressed contacts before migration reduces your Mailchimp plan band and lowers ongoing costs.
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 ActiveCampaign 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.
ActiveCampaign
Contact
Mailchimp
Audience Member
1:1ActiveCampaign Contacts map 1:1 to Mailchimp Audience Members. The email address is the dedupe key on both platforms. We export all standard contact fields (first name, last name, email, phone, address) and custom field values, then map them to Mailchimp merge fields. ActiveCampaign's contact status (active, unsubscribed, bounced) maps to Mailchimp's subscription status so that suppressed records import as unsubscribed rather than active contacts.
ActiveCampaign
Tag
Mailchimp
Tag
1:1ActiveCampaign Tags migrate 1:1 to Mailchimp Tags. Tags are a flat label system on both platforms with no value mapping required. We export the full tag taxonomy and reassign each tag during Mailchimp import. Note that Mailchimp Tags are audience-specific; if the migration involves multiple ActiveCampaign Accounts or multiple Pipelines, we recommend consolidating to a single Mailchimp Audience or splitting carefully to avoid tag fragmentation.
ActiveCampaign
Account
Mailchimp
Audience Member merge fields (company)
many:1ActiveCampaign Accounts have no direct Mailchimp equivalent. Company name, domain, industry, and address data from Accounts associate with Contacts via the Account-Contact relationship in ActiveCampaign. We flatten this by attaching Account-level fields to the Contact record as merge fields (COMPANY, INDUSTRY, ADDRESS, CITY, STATE, COUNTRY). If the same Account has multiple Contacts, the Account data copies to each related Contact.
ActiveCampaign
Deal
Mailchimp
Not supported
lossyActiveCampaign Deals have no Mailchimp equivalent. Mailchimp is an email marketing platform with basic CRM features; it does not support pipeline management, deal stages, deal values, or deal ownership. We do not migrate Deals. We deliver a written Deal inventory showing each deal's name, value, stage, owner, associated contact, and close date so the customer's admin can decide whether to recreate them as Notes, Tasks, or a separate spreadsheet.
ActiveCampaign
Pipeline
Mailchimp
Not supported
lossyActiveCampaign Pipelines (the container objects defining deal stages and probabilities) have no Mailchimp equivalent. Mailchimp has no concept of deal stages, weighted pipeline values, or pipeline-level reporting. We document the Pipeline structure including all stage names, order, and probability values in the migration inventory for the customer's admin to assess if any of this information is worth recreating in another tool.
ActiveCampaign
Automation
Mailchimp
Not supported
lossyActiveCampaign Automations are JSON workflow definitions that cannot be exported via API. Mailchimp's Customer Journey Builder uses a different step-based architecture that does not accept imported automation logic. We do not migrate Automations as code. We deliver a written automation inventory documenting each ActiveCampaign Automation's trigger, conditions, actions, and wait steps so the customer's team can rebuild them in Mailchimp's Customer Journey Builder.
ActiveCampaign
Custom Field (Contact)
Mailchimp
Merge Field
1:1ActiveCampaign custom contact fields map to Mailchimp Merge Fields. We extract the custom field schema including field type (text, number, date, dropdown, checkbox, phone, URL) and recreate the equivalent merge field in Mailchimp before importing contact data. Merge field names in Mailchimp are uppercase and alphanumeric (e.g., HOMEPHONE, BIRTHDAY, LOYALTYTIER). We handle type mapping (ActiveCampaign date fields become Mailchimp date merge fields) and format any required validation.
ActiveCampaign
Form
Mailchimp
Mailchimp Signup Form
lossyActiveCampaign Forms export their field configurations. We provide a field-level mapping document showing which ActiveCampaign form fields correspond to Mailchimp merge fields. Complex conditional logic, branching rules, and form automation triggers do not transfer; Mailchimp forms support basic conditional logic but the customer's admin must recreate the full form behavior in Mailchimp's form builder.
ActiveCampaign
Campaign History
Mailchimp
Campaign Reports (limited)
lossyActiveCampaign campaign reports (sends, opens, clicks, bounces, unsubscribes per campaign) export as CSV. We extract these reports and deliver them as a historical reference document. Mailchimp campaign reports do not receive imported historical data; the reporting timeline starts from the date of Mailchimp account activation. We deliver the historical data as a supplemental CSV for the customer's analytics team to import into a separate reporting tool if needed.

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.
ActiveCampaign gotchas
Contact billing counts all statuses including unsubscribes and bounces
Deal notes are not exported via API or CSV
Automations cannot be exported or migrated programmatically
Bulk Contact Importer rate limit is 20 requests per minute for single contacts
HubSpot migration maps Products to custom deal fields, not a native equivalent
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
Scoping and contact inventory
We audit the ActiveCampaign account to count total contacts by status (active, unsubscribed, bounced, unconfirmed), catalog custom field schemas, extract the tag taxonomy, document Deal and Pipeline structures, and list active Automations. We also assess whether the account has multiple Pipelines or Account-contact relationships that affect audience segmentation strategy. The scoping output is a written scope document with record counts, field mapping table, and a data gap disclosure listing all non-migratable objects.
Suppression list cleanup and contact archiving
Before data extraction, we work with the customer to archive or permanently delete suppressed ActiveCampaign contacts (bounced and unconfirmed) to reduce the contact volume moving to Mailchimp and lower the ongoing subscription cost. We export the full suppression list (email addresses and status) separately so that it can be imported as a Mailchimp suppression list, ensuring these contacts do not receive any future Mailchimp sends regardless of their original ActiveCampaign status.
Mailchimp audience and schema setup
We create the destination Mailchimp audience and pre-configure all merge fields to match the ActiveCampaign custom field schema before any contact import. Merge field names are converted to Mailchimp's uppercase alphanumeric format. For accounts with multiple ActiveCampaign Pipelines, we recommend audience segmentation strategy (single consolidated audience with tags versus multiple audiences) based on the customer's list management needs.
Contact and tag migration
We export ActiveCampaign Contacts and Tags, apply field-level transformations (email normalization, status mapping, consent mapping), and import into Mailchimp using the Mailchimp API with batch processing. Tags migrate as audience-level tags. The suppression list (unsubscribes and bounces from ActiveCampaign) imports as a Mailchimp suppression list separately so these addresses are permanently blocked from future sends.
Account data flattening and deal inventory delivery
We export ActiveCampaign Account data (company name, industry, address, domain) and attach it to the related Contact records as merge fields. ActiveCampaign Deals and Pipelines are not migrated; instead, we deliver a written Deal inventory CSV listing every Deal with its name, value, stage, owner, associated contact email, and close date. The customer's admin decides whether to recreate these as Notes, Tasks, or a separate spreadsheet.
Automation inventory and migration handoff
We deliver a written automation inventory documenting every ActiveCampaign Automation with its trigger type, conditions, actions, and step sequence. This document is the handoff artifact for the customer's team to rebuild automations in Mailchimp's Customer Journey Builder. We do not rebuild automations as part of the migration scope. For Mailchimp Essentials accounts, we note which ActiveCampaign automations may need simplification due to the 4-step journey limit. We offer a separate automation rebuild engagement if the customer wants hands-on assistance recreating workflows.
