Overview
Moving from HoneyBook to Mailchimp is a platform-type migration: HoneyBook is an all-in-one clientflow platform for creative independents, combining CRM, invoicing, contracts, and payment processing under one subscription; Mailchimp is an email marketing and audience management platform. The only data that transfers programmatically between them is contact records and company associations, because HoneyBook has no public bulk API and Mailchimp has no native object for projects, invoices, contracts, pipelines, or payments. We extract contacts from HoneyBook's CSV export, split combined names into Mailchimp's FNAME and LNAME merge fields, map company names to audience tags for segmentation, and import everything via Mailchimp's bulk import API. We flag non-transferable records in a written inventory so your admin handles invoices, contracts, and project context outside the migration. We do not migrate automations or workflows as code; Mailchimp's Customer Journey builder uses a different automation model, and we deliver an Automation Inventory with a recommended journey mapping instead.

Object mapping
Each row shows how a HoneyBook 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.
HoneyBook
Contact
Mailchimp
Mailchimp Audience Member
1:1HoneyBook contacts export as a CSV from Clients > Contacts and include name, email, phone, address, notes, and creation date. HoneyBook stores the full name in a single field; Mailchimp uses separate FNAME and LNAME merge fields. We split the combined name at migration time, using the first space as the boundary between first and last name. Any contacts without a valid email address are flagged in a separate report because Mailchimp requires a valid email address for subscriber records. Merge fields from HoneyBook custom fields map to Mailchimp merge fields where the field type is compatible (text, number, date, phone, address, URL). Dropdown and multi-select custom fields that Mailchimp does not support natively become tags in the format 'CF: FieldName = Value'.
HoneyBook
Company
Mailchimp
Mailchimp Audience Member (COMPANY merge field + company name tag)
lossyHoneyBook company records have no direct Mailchimp equivalent because Mailchimp does not maintain an Account object separate from contacts. We map the company name to the COMPANY merge field on the contact record and apply a tag using the company name (for example, tag 'Company: Acme Photography') so that audience segments can be built by company. If multiple contacts share the same company name in HoneyBook, they receive the same tag in Mailchimp. Company-level reporting in Mailchimp relies on tag-based segmentation rather than a parent-child relationship.
HoneyBook
Project
Mailchimp
Not applicable (no equivalent)
1:1HoneyBook projects contain inquiries, pipeline stages, custom fields, files, and associated contacts. Mailchimp has no project or pipeline object, so projects cannot be created as native records in the destination. We tag each contact with a tag reflecting their associated HoneyBook project membership using the format 'Project: [Project Name]' so that project context is preserved as audience segmentation in Mailchimp. The full project list (project name, stage, client association, stage history timestamps) is exported to a separate Project Inventory CSV for the customer's reference. Customers who rely on HoneyBook projects for project management need to handle this function in a separate tool post-migration.
HoneyBook
Invoice
Mailchimp
Not applicable (no equivalent)
1:1HoneyBook invoices include line items, payment status, amounts, and client associations. Mailchimp has no invoice or payment object. We extract open invoice metadata (client name, invoice number, amount, status, issue date, due date) to a separate Invoice Inventory CSV for the customer's accounts-receivable team to process manually in their new payment tool. Closed invoices (settled payments) are not migrated because the financial record remains in HoneyBook for audit purposes. Auto-payment profiles connected to HoneyBook invoices are flagged during discovery and must be redirected to the customer's new payment processor before cutover to prevent duplicate or failed charges.
HoneyBook
Contract
Mailchimp
Not applicable (no equivalent)
1:1HoneyBook contracts store template-based documents with client associations and e-signature status. Mailchimp has no contract object. We extract contract metadata (client name, template name, status, date signed, signature method) to a Contract Inventory CSV. Contract PDF files are session-bound and not publicly accessible via a direct URL, making programmatic file extraction unreliable. Customers should manually download active contract PDFs from HoneyBook before or after cutover. The Contract Inventory CSV documents which contracts require this manual step.
HoneyBook
Pipeline Stage
Mailchimp
Not applicable (no equivalent)
1:1HoneyBook pipelines have configurable stages (Inquiry, Follow Up, Proposal Sent, Booked, Completed) with move-time tracking per project. Mailchimp does not support pipeline or project-stage objects. Stage history and timestamps are included in the Project Inventory CSV exported alongside the contact migration. Customers who need to preserve pipeline context use the project inventory and contact project-tags as a written reference rather than a live record.
HoneyBook
Custom Field (contact-level)
Mailchimp
Mailchimp Merge Field or Tag
lossyHoneyBook custom fields on contacts support mixed field types. Mailchimp merge fields support eight types: text, number, date, phone, address, URL, dropdown, and radio. During discovery we audit every active HoneyBook custom field, classify each by type, and map compatible types directly to Mailchimp merge fields. Dropdown fields become Mailchimp dropdown merge fields; radio fields become radio merge fields. Multi-select, checkbox, and file-type custom fields that Mailchimp does not support become tags in the format 'CF: [Field Name] = [Value]' applied to the contact at import time.
HoneyBook
Team Member
Mailchimp
Mailchimp Audience Member (if client contact) or Admin User (if staff only)
1:1HoneyBook distinguishes between collaborators (external, limited access) and team members (internal). Team members who are also HoneyBook client contacts migrate as Mailchimp contacts with a ROLE merge field capturing their internal role. Staff-only team members (no associated client contact) have no direct Mailchimp equivalent and are exported to a Team Member Inventory CSV for manual Mailchimp admin user setup post-migration. HoneyBook Balance checking account holders must coordinate with HoneyBook support to close or transfer the account separately, as it is a banking product outside the scope of standard record migration.

HoneyBook gotchas
No public bulk API forces manual data export
Payment processing fees apply to every transaction
Bank transfers take 7–8 days to process
HoneyBook Balance is a separate banking product
Limited international availability affects data residency
Mailchimp gotchas

Migration approach
Discovery and contact audit
We audit the source HoneyBook account to identify the total contact count, company count, active custom fields, and any HoneyBook automations in use. We extract the contacts CSV from the Clients > Contacts panel, note the company associations per contact, and identify contacts without valid email addresses. We also extract project names and pipeline stage values from the HoneyBook pipeline view to build the Project Inventory. The discovery output is a written scope confirming record counts, custom field mapping, and a list of non-transferable objects requiring post-migration manual handling.
Data extraction and transformation
We extract all contact records and company associations from HoneyBook. The combined-name field is split into first name and last name using the first space as the delimiter, with single-word names flagged for review. Company names are extracted as a separate column for tagging. HoneyBook custom fields are mapped to Mailchimp merge field types. Invoices, contracts, and project context are extracted to separate inventory CSVs rather than imported into Mailchimp. All extraction uses CSV downloads and HoneyBook's authenticated web interface, not a bulk API because HoneyBook exposes no programmatic export endpoint.
Audience setup in Mailchimp
We create the Mailchimp audience (or use the existing audience) and pre-configure the merge fields required by the custom field mapping before importing any contacts. If the contact volume exceeds Mailchimp's free-plan limit for the selected tier, we confirm the customer's intended plan before proceeding. Tags for company names and project memberships are pre-created as audience tags so they are available at import time. Any contacts without valid email addresses are excluded from the main import and listed in a separate Undeliverable Contacts report.
Bulk contact import and reconciliation
We import contacts via Mailchimp's bulk import API using the prepared CSV. Email address serves as the dedupe key. Any records rejected due to format errors or duplicate suppression rules are logged and retried or flagged for the customer's admin. Company tags and project tags are applied in the same import pass using Mailchimp's tag-on-import feature. The customer receives a reconciliation report comparing the source HoneyBook contact count against the Mailchimp audience member count with any discrepancies explained.
Automation and non-transferable inventory delivery
We deliver the Automation Inventory document listing each HoneyBook automation with its trigger type, conditions, actions, and recommended Mailchimp Customer Journey mapping. We also deliver the Project Inventory CSV (project names, stage history, client associations), Invoice Inventory CSV (open invoice metadata), and Contract Inventory CSV (contract metadata with manual download flag). These inventories are customer-facing documents that the admin uses to recreate records and automations outside the migration scope.
Cutover, validation, and pre-send hygiene
We run a final delta check to identify any contacts added or modified in HoneyBook during the migration window and import them before cutover. We advise the customer to send a re-confirmation email from HoneyBook to non-marketing-consented contacts before import to protect Mailchimp sender reputation. After cutover, the customer tests a sample campaign send to verify deliverability, tag-based segmentation accuracy, and merge field population. We do not provide post-migration admin support, training, or Customer Journey rebuild as standard scope; these are separate engagements.
