Overview
Moving from Keap to Mailchimp is a shift from a full small-business CRM with sales pipeline and marketing automation to an audience-centric email marketing platform with basic CRM features. Mailchimp does not have a native pipeline or opportunity object, so deals require a decision before migration — either create them as Mailchimp tags or custom fields, or acknowledge they are out of scope. We extract contacts with their full tag assignments and custom field values via Keap's REST API, create Mailchimp audiences and matching merge fields, and import in tag-segmented batches to preserve Keap's segmentation logic. Keap automation sequences cannot be exported structurally and must be rebuilt from a written inventory we deliver. The pricing difference is significant — Keap starts at $169 per month while Mailchimp starts at $13 per month for comparable contact volumes, making the switch attractive for teams moving from a full CRM to an email-first platform.

Object mapping
Each row shows how a Keap 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.
Keap
Contact
Mailchimp
Subscriber (Audience Member)
1:1Keap Contacts map to Mailchimp Subscribers within an Audience. We use email address as the dedupe key and import contacts in tag-segmented batches so that each Mailchimp Audience contains contacts from the corresponding Keap tag group. Standard fields (first name, last name, email, phone, address) map to Mailchimp's merge field equivalents (FNAME, LNAME, EMAIL, PHONE, ADDRESS). Custom fields from Keap map to Mailchimp merge fields, but text-area fields exceeding 255 characters must be truncated or split into multiple merge fields, which we flag during scoping.
Keap
Company
Mailchimp
Custom Merge Field or Notes
lossyMailchimp has no native company or account object. Keap Companies are stored as values in a Company Name merge field on the Subscriber record, or in a Notes section if the company name exceeds what fits in a standard merge field. For contacts with multiple associated companies in Keap, we flag this as a many-to-one scenario that requires the customer to decide which company to promote during migration. If the customer needs full company-level reporting, Mailchimp's Basic tier and above supports multiple audiences, which can be used to segment by company.
Keap
Tag
Mailchimp
Tag
1:1Keap tags map directly to Mailchimp tags on each Subscriber record. We export the complete tag taxonomy from Keap and apply tags to Mailchimp subscribers in the same groupings. Mailchimp's tag model supports multiple tags per subscriber, matching Keap's tag capability. We batch contacts by tag during import to avoid Mailchimp's per-minute tag operation limits on larger audiences. If Keap tags number in the hundreds, we consolidate to the top 50-100 most-used tags and flag overflow for manual cleanup.
Keap
Opportunity (Pipeline Deals)
Mailchimp
Custom Field or Tag (out of scope decision)
lossyMailchimp has no native pipeline or deal tracking object. We raise this as an explicit scoping decision before migration. Options include: importing pipeline stage as a subscriber tag (e.g., DealStage-Present, DealStage-Won), creating a custom merge field for deal value, or excluding opportunities entirely. We document the customer's choice and implement accordingly. If the customer needs CRM-level pipeline management post-migration, we recommend pairing Mailchimp with a lightweight CRM like Pipedrive or HubSpot Starter, which is a common hybrid pattern for Keap ex-customers.
Keap
Automation Sequence
Mailchimp
Customer Journey (must rebuild)
1:1Keap automation sequences store step definitions in a proprietary format inaccessible via API. We export sequence names, step counts, and trigger condition summaries as a written inventory document for the customer to use when rebuilding in Mailchimp Customer Journeys. The rebuild requires manual recreation because Keap's tag-triggered, time-delayed sequences with conditional branching do not have a direct Mailchimp equivalent. We deliver a row-per-sequence document mapping each Keap sequence to the closest Mailchimp Customer Journey trigger and action pattern.
Keap
Invoice
Mailchimp
Out of scope
lossyMailchimp does not have an invoice or order management object. Keap invoices are flagged as out of scope for this migration. We export invoice records as a CSV reference file for the customer's accounting team to handle separately in their accounting software. Invoice totals and statuses are not migrated into Mailchimp; if the customer needs invoice history accessible in the marketing platform, a note field or custom merge field can be populated with a summary, but full invoice records require an external accounting tool.
Keap
Product
Mailchimp
Out of scope or Item
lossyMailchimp's e-commerce features (available on Standard and Premium tiers) support products and abandoned cart automations, but the product catalog must be built manually or imported via Mailchimp's CSV product import. We export Keap products as a CSV with name, SKU, price, and description for manual upload into Mailchimp's product catalog. Product images and advanced catalog features do not transfer and require re-upload.
Keap
Task
Mailchimp
Activity Log or Out of scope
lossyMailchimp does not have a task management object equivalent to Keap's CRM tasks. We raise task records as out of scope for the standard migration, but we export them as a CSV file for the customer's reference if they need to migrate to a separate task management tool. If the customer is adopting a hybrid setup with Mailchimp for email and a separate CRM for task management, we can include task records in the migration scope for that destination system.
Keap
Note
Mailchimp
Subscriber Note or Campaign Archive
1:1Keap notes associated with contacts migrate as subscriber notes in Mailchimp if the customer is on the Standard tier or above. Notes are imported as note entries on the subscriber profile, preserving the note body and author. Free-form notes without an associated contact date are imported with the creation timestamp. Note attachments do not migrate; we flag any contacts with attachments for manual follow-up.
Keap
Campaign (Email)
Mailchimp
Campaign Archive
1:1Keap email campaign metadata (name, status, recipient tag, send date) migrates as a campaign history reference. Email body content can be exported via Keap's REST API, but HTML assets, images hosted on Keap's CDN, and embedded content do not transfer cleanly. We export campaign content as HTML text files for manual re-upload into Mailchimp's campaign builder. The campaign name and send history serves as a reference for the customer to recreate campaigns in Mailchimp with similar audience segments.
Keap
Custom Field
Mailchimp
Merge Field
1:1Keap custom fields discovered via the /retrieveContactModel endpoint map to Mailchimp merge fields. Mailchimp merge fields have a 255-character limit on text fields, which means long-text area fields from Keap must be truncated or split into multiple merge fields. We flag any custom field exceeding 255 characters during discovery and ask the customer to decide whether to truncate, split, or exclude. Date fields map to Mailchimp date merge fields, number fields map to number merge fields, and checkbox fields map to Mailchimp radio or dropdown merge fields depending on the source field type.
Keap
User (Team Member)
Mailchimp
Out of scope
lossyMailchimp uses a permission-based team model without per-user seat billing on the free and Essentials plans. Keap users and team member accounts are not migrated as Mailchimp users; instead, the customer provisions Mailchimp user accounts post-migration. We export the Keap user list as a reference CSV for the customer to use during Mailchimp team setup.

Migration approach
Discovery and data audit
We audit the source Keap account across object types: contact count, company count, tag taxonomy size, pipeline count and stage names, opportunity count, custom field definitions via the /retrieveContactModel endpoint, automation sequence names and step counts, and invoice record volume. We probe both the REST API and XML-RPC endpoints to identify parity gaps and determine which API path returns the most complete data. We deliver a written data inventory document listing every object type, record count, and any fields that require manual extraction due to API limitations. This document serves as the migration scope baseline and the basis for the scoping call where the customer decides how to handle pipeline deals, long-text custom fields, and automation sequences.
Mailchimp audience design and merge field creation
We create Mailchimp audiences to match the customer's segmentation strategy, typically one audience per major Keap tag group or contact segment. Before importing contacts, we create all required merge fields in Mailchimp corresponding to Keap's custom fields, with field types matched (text to text, date to date, number to number). Any Keap custom field exceeding 255 characters is flagged and resolved per the customer's chosen strategy before merge field creation. If the customer is on a Mailchimp tier that supports multiple audiences, we configure audience defaults and tag-based routing rules to replicate Keap's segmentation logic.
Contact and company export via Keap REST API
We export Keap contacts in paginated batches using the REST API with exponential backoff to respect the 500 calls per minute rate limit. For each contact, we extract standard fields, all associated tags, all associated company links, and all custom field values. Company records are exported separately and mapped to the Company Name merge field on each contact. We resolve the contact-to-company relationship by extracting the primary company association from Keap's Company record link. Any contacts with duplicate email addresses are flagged for the customer to resolve before import; Mailchimp requires unique email addresses per audience.
Tag mapping and batch import
We map Keap tags directly to Mailchimp tags, applying all tags to each subscriber record during import. For tag taxonomies exceeding 100 unique tags, we consolidate to the most-used tags and flag the remainder for manual cleanup post-migration. Contacts are imported in tag-segmented batches to respect Mailchimp's per-minute tag operation limits. After import, we run a reconciliation check comparing the total tag assignments in Keap against the total tag assignments in Mailchimp, with a tolerance of less than 1 percent variance due to Mailchimp's eventual consistency model for tag updates.
Automation sequence inventory and campaign content export
We extract Keap automation sequence metadata (name, step count, trigger type, associated tags) as a written inventory document. Email campaign content is exported as HTML text files where accessible via REST API. Images hosted on Keap's CDN are flagged for manual re-upload to Mailchimp's content studio. The sequence inventory document is delivered to the customer as the primary artifact for rebuilding Keap automations in Mailchimp Customer Journeys. This step does not include any automated migration of sequence logic because the data format is not accessible.
Cutover, validation, and handoff
We freeze writes to the Keap account during the final cutover window, run a delta export of any records modified since the initial export, and import the delta into Mailchimp. We run a final reconciliation comparing total subscribers imported against total contacts exported, tag assignment counts, and custom field population rates. We deliver the automation sequence inventory document, the campaign content export, and a post-migration data dictionary mapping each Keap field to its Mailchimp equivalent. We do not rebuild Keap automation sequences in Mailchimp as part of the migration scope; the customer uses the inventory document to recreate sequences in Mailchimp Customer Journeys. We provide a one-week hypercare window for reconciliation issues raised during the first send.
