Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Convertkit

What's pushing teams away

  • September 2025 price increases raised Creator plan costs significantly, with some creators reporting bills tripled at the same subscriber count.
  • Kit's branding on landing pages, emails, and product pages remains until manually toggled off on paid tiers, which creators find unprofessional for paid product sales.
  • Free tier allows no A/B testing and restricts users to one account and basic templates, pushing creators toward upgrades for features that competitors include on lower plans.
  • Export functionality on lower tiers is limited, with some creators reporting difficulty accessing their data when evaluating departures.
  • Sequences and automations cannot be exported in a machine-readable format, requiring complete manual rebuild on the destination platform.

Choosing

What's pulling them in

  • Lowest barrier to entry of any major CRM — the free tier with unlimited contacts lets teams validate fit before committing to a paid plan, according to G2 and Capterra reviewers.
  • Native integration between the CRM and sales engagement tools (sequences, email tracking, dialer) means no separate sync configuration, a theme across G2 Sales Hub reviews.
  • Pipeline visualization, deal tracking, and automated workflows are consistently praised as intuitive and easy to set up without developer involvement.
  • Strong onboarding for new team members — reviewers on Capterra and G2 highlight how quickly new reps become productive without formal training.
  • The HubSpot platform ecosystem (Marketing, Sales, Service, CMS hubs) allows growing companies to consolidate tools without building new integrations.

Object mapping

How Convertkit objects map to HubSpot

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

maps to

HubSpot

Contact

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

Contact Property or Static List

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

Contact Property

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Form

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Landing Page

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Sequence + Workflow

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Email (Campaign)

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Product

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

Deal + Line Item

many:1
Fully supported

ConvertKit 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

maps to

HubSpot

Contact createDate property

1:1
Fully supported

Original 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

maps to

HubSpot

Contact opt-out status

1:1
Fully supported

ConvertKit 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

maps to

HubSpot

HubSpot Private App

1:1
Fully supported

ConvertKit 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.

Pair-specific challenges

  • ConvertKit tags lack native HubSpot equivalent — mapping strategy determines segmentation usability

    ConvertKit tags are flat strings with no hierarchy or typing. A subscriber can have 50 tags. HubSpot uses contact properties (key-value pairs) and static lists. We map tags to either a single 'converkit_tags' property (semicolon-delimited) for reference, or to individual boolean or picklist properties per tag value. If your segmentation relies on tag combinations, map them to HubSpot lists based on filter rules — but this requires rebuilding segment logic in HubSpot. The choice affects every report, workflow trigger, and email send in HubSpot, so it must be decided before migration commits.

  • ConvertKit sequences cannot be exported — rebuild is required in HubSpot's workflow builder

    ConvertKit sequences store email content, timing rules, trigger conditions, and subscriber progression as a proprietary format. HubSpot sequences and workflows store logic differently — triggers, conditions, and delays are configured in HubSpot's visual workflow builder. We export sequence emails as HTML documents and document the sequence structure (steps, delays, branch conditions) as a rebuild reference. Your HubSpot admin rebuilds each sequence manually. This is the largest manual effort in the migration. Plan 2–4 hours per sequence for rebuilding plus testing.

  • ConvertKit subscriber has no native company — HubSpot requires contacts to be associated with companies for deal linking

    ConvertKit subscribers are standalone records. HubSpot deals require a ContactId and an AccountId (company) to appear in the revenue pipeline. Subscribers without a company domain in their email address default to a 'Unassigned' HubSpot company record. If your team uses HubSpot deals, we recommend identifying subscribers who map to real companies and linking them before deal creation. This may require a domain-based company lookup or manual assignment step before migration finalizes.

  • ConvertKit products and purchases map to HubSpot deals — but deal pipeline stages must be configured first

    ConvertKit purchases migrate as HubSpot deals with the product as a line item. However, HubSpot deal pipelines have stages, probabilities, and forecast categories that must be created before records land. If your team doesn't use HubSpot deals, purchases can be stored as line items on a dummy deal or as custom properties on the contact. We recommend deciding your deal pipeline strategy before migration begins — pipeline configuration is part of the pre-migration schema setup phase.

  • ConvertKit's 140 custom field limit means complex accounts have high field density — HubSpot property limits apply

    ConvertKit allows 140 custom fields per account. If you've used most of them, HubSpot's property creation process becomes time-intensive. HubSpot contact properties are capped at 500 by default; custom objects handle overflow at Enterprise tiers. We create HubSpot properties in batches, matching ConvertKit field types to HubSpot property types. Long text fields in ConvertKit map to HubSpot multi-line text properties. Validation rules and required-field settings must be reconfigured in HubSpot post-migration.

Migration approach

Six steps for a successful Convertkit to HubSpot data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Strengths

  • Unlimited email sends across all paid tiers regardless of list size.
  • Generous free tier supporting up to 10,000 subscribers with core features.
  • Free migration assistance from competitor platforms on Creator and Creator Pro plans.
  • Tag-based segmentation is intuitive for creators managing audience organization.
  • Clear subscriber-count pricing model without per-email or per-send charges.

Weaknesses

  • September 2025 price increases significantly raised costs at same subscriber counts.
  • Sequences and automations cannot be exported in a machine-readable format.
  • Kit branding on emails and landing pages requires manual toggle on paid tiers.
  • Custom fields limited to 140 per account, which may constrain complex data collection.
  • Free tier has no A/B testing and is restricted to a single user account.

Destination

Strengths

  • Genuinely useful free CRM tier with no seat limit on contact records.
  • All-in-one sales engagement layer (sequences, email tracking, calling, dialer) embedded natively in the CRM, eliminating a separate integration.
  • Intuitive interface and fast onboarding for individual reps, per G2 and Capterra reviews.
  • Workflow automation triggers across contacts, deals, and tickets with a visual builder.
  • API coverage for all standard objects including custom objects at Enterprise tier.

Weaknesses

  • Pricing model is contact-based at the marketing layer — importing all records as marketing contacts can multiply the monthly bill by 4×.
  • Feature tier cliffs are frequent surprises: sequences, calling, advanced reporting, and quoting are all gated, often requiring plan upgrades mid-implementation.
  • Mandatory onboarding fees at Professional ($1,500) and Enterprise ($3,500) are not prominently disclosed on the pricing page.
  • API rate limits are restrictive for bulk migration — burst limits of 100-200 req/10sec and search endpoint limits of 4 req/sec require careful job queuing.
  • Custom objects, additional pipelines, and advanced forecasting are Enterprise-only, making cost projections difficult for growing teams.
