Overview
ConvertKit organizes data around subscribers, tags, forms, and sequences — a flat email-centric model without native CRM objects like companies or deals. HubSpot uses contacts, companies, deals, and a lifecycle_stage property that defines each contact's position in the customer journey. The migration carries ConvertKit subscriber records (email, name, custom fields) into HubSpot contacts, converts tags to HubSpot contact properties or list memberships, and maps custom fields to HubSpot property definitions. HubSpot sequences and workflows do not migrate automatically — they require manual rebuilding in HubSpot's workflow builder. We export ConvertKit form data and email sequence content as reference documents your team uses to rebuild automations. The migration uses ConvertKit's API export and HubSpot's bulk import API, with field-level validation before committing records. A 24–48 hour delta window captures any new subscribers created during cutover so your HubSpot instance reflects ConvertKit's final state at go-live. Field-level validation includes checking for duplicate emails, missing required properties, and data type mismatches before final import. Additionally, we document any tag or custom field anomalies to help your team prioritize data cleanup.
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 Convertkit object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Convertkit
Subscriber
HubSpot
Contact
1:1ConvertKit subscribers map directly to HubSpot contacts. Email address is the unique identifier. Each subscriber becomes a contact record with all standard properties (name, email, created date) preserved. Subscribers without email addresses cannot migrate. We also validate email format and check for duplicates before import to avoid overwriting existing contacts.
Convertkit
Tag
HubSpot
Contact Property or Static List
1:1ConvertKit tags are free-form strings applied N-to-N to subscribers. We map tag values to either HubSpot contact properties (when tag represents a trait like 'customer_type') or HubSpot static lists (when tag represents a segment for targeted sends). Tag frequency data preserved as property values.
Convertkit
Custom Field
HubSpot
Contact Property
1:1ConvertKit custom fields map 1:1 to HubSpot contact properties. Property type (text, number, date, dropdown) is preserved. Maximum 140 ConvertKit custom fields; HubSpot allows 500+ contact properties by default. Field key becomes the property name in HubSpot. We also verify that picklist values match HubSpot's allowed options before migration.
Convertkit
Form
HubSpot
HubSpot Form
1:1ConvertKit forms do not migrate as functional HubSpot forms. We export form field names, submission logic, and styling as a rebuild reference. HubSpot forms are created manually or via HubSpot's form builder. Form-field-to-contact-property mapping documented for recreation. We also include screenshots of original forms to aid designers in recreating the look and feel.
Convertkit
Landing Page
HubSpot
HubSpot Landing Page
1:1ConvertKit landing pages do not transfer to HubSpot landing pages. HTML structure and content exported as reference documents. Landing pages must be rebuilt in HubSpot's CMS or external tools. We map page URLs and form associations for redirect planning. We also capture meta tags and SEO titles for each page to preserve search visibility after migration.
Convertkit
Sequence
HubSpot
HubSpot Sequence + Workflow
1:1ConvertKit sequences (automated email drip series) cannot be exported as functional HubSpot sequences or workflows. Email content exported as HTML documents. Sequence logic (triggers, delays, conditions) documented for manual rebuild in HubSpot Sales Hub sequences or Operations Hub workflows. We also provide timing diagrams and decision trees to clarify each step during the rebuild process.
Convertkit
Broadcast
HubSpot
HubSpot Email (Campaign)
1:1ConvertKit broadcasts (one-time email sends) do not migrate as live HubSpot campaigns. Broadcast content, subject lines, send dates, and audience lists exported as reference. We preserve the broadcast history as a custom property on each contact (last broadcast received, broadcast names).
Convertkit
Product
HubSpot
HubSpot Product
1:1ConvertKit products (digital goods, paid newsletters) map to HubSpot products. Product name, price, and description transferred. HubSpot product records can be linked to deals if your team uses the e-commerce or quote features. We also ensure product images and URLs are included for reference in HubSpot's product library.
Convertkit
Purchase
HubSpot
Deal + Line Item
many:1ConvertKit purchase events merge into HubSpot deal and line item records. Each purchase becomes a deal linked to the contact, with product details as line items. Deal stage set to 'Closed Won' by default. Purchase timestamps preserved on the deal record.
Convertkit
Subscriber Created Date
HubSpot
Contact createDate property
1:1Original subscriber creation timestamps preserved as a HubSpot contact property (Original_Subscriber_Created_Date__c). HubSpot's native CreatedDate reflects migration time; the custom property preserves the original ConvertKit date for reporting continuity. We also update any date-based workflows or reports to reference the custom property, ensuring historical trends remain accurate after migration.
Convertkit
Subscriber Email Unsubscribe
HubSpot
Contact opt-out status
1:1ConvertKit unsubscribe flags map to HubSpot's contact email opt-out property. Unsubscribes transfer as active opt-outs so HubSpot respects existing suppression. Re-subscribes in ConvertKit before migration cutover are honored. We also verify opt-out timestamps are recorded for compliance reporting and audit trails.
Convertkit
API Key / Account Settings
HubSpot
HubSpot Private App
1:1ConvertKit API credentials and account configuration do not map to HubSpot equivalents. We export account settings (from name, reply-to address, sender branding) as a checklist for HubSpot account configuration. Private apps in HubSpot created separately. We also document IP whitelisting and webhook URLs for future integration setup.

Migration approach
Export ConvertKit data via API and validate field inventory
We connect to ConvertKit's API using your account credentials and export all subscribers, tags, custom field definitions, products, purchases, form submissions, and sequence metadata. The export produces a structured data dictionary showing every ConvertKit field, its type, sample values, and null frequency. We validate record counts, identify duplicate emails, and flag records missing required fields (email address) before mapping begins.
Design HubSpot property schema and tag mapping strategy
Based on the ConvertKit field inventory, we design the HubSpot contact property schema. Each ConvertKit custom field gets a corresponding HubSpot property with matched type. For ConvertKit tags, we present two options: store all tags as a single custom property, or decompose high-value tags into individual HubSpot properties or list memberships. Your team approves the mapping strategy before property creation. We create all HubSpot properties in your account using the HubSpot API.
Configure HubSpot deal pipelines (if applicable) and link products
Configure HubSpot deal pipelines (if applicable) and link products. If your migration includes ConvertKit purchase data, we set up HubSpot deal pipelines matching your revenue reporting needs. Each ConvertKit product becomes a HubSpot product record. Purchase transactions map to deals with line items linking to the product. We configure deal stages, probabilities, and any custom deal properties needed for your sales process before subscriber records are loaded. We also test pipeline stage transitions with sample deals to confirm reporting accuracy.
Run sample migration with field-level diff on 100–500 records
We migrate a representative sample of ConvertKit subscribers — including contacts with tags, custom field values, and purchase history — into your HubSpot account. Field-level validation compares source values against destination values for every mapped property. You review the diff report, confirm tag mapping results, and approve any adjustments to the mapping before the full migration runs. This step catches property type mismatches and value mapping gaps before committing large record volumes.
Execute full migration with delta-pickup window
The full migration loads all ConvertKit subscribers into HubSpot contacts, applies tag mappings and custom field values, creates company associations, and generates deal records for purchase history. A 24–48 hour delta window captures any new subscribers or tag changes made in ConvertKit during cutover. All operations are logged to an audit trail. If reconciliation identifies missing records or mapping errors, one-click rollback reverts the migration for correction.
