Overview
ConvertKit structures its data model around Subscribers, Tags, Visual Automations (sequences), Broadcasts, Forms, Landing Pages, and Commerce products. HighLevel uses Contacts, Tags, Workflows (trigger-based), Campaigns, Forms, Funnels, and Opportunities (pipeline-driven). These models overlap at the contact level but diverge significantly in how automation logic is expressed — ConvertKit's visual automation builder has no equivalent in HighLevel's system, and ConvertKit sequences are not transferable to HighLevel's Workflow sequences. We migrate ConvertKit subscriber profiles directly into HighLevel Contacts, preserving all standard fields (email, first name, last name, phone, address) plus every custom field you have defined (up to ConvertKit's 140-field limit). Tags migrate as HighLevel tags with their original names and association counts. Forms and landing pages are exported for rebuild in HighLevel's drag-and-drop builder. Your email engagement history (opens, clicks per broadcast) is stored as custom contact fields in HighLevel because HighLevel's activity model is prospective, not historical. The migration uses ConvertKit's REST API and bulk CSV exports, paired with HighLevel's Contacts API and bulk import endpoint. Visual automations and sequences are not migrated — they are documented in a structured format your team uses to rebuild in HighLevel's Workflow builder. This is the honest scope: data moves, automation logic is preserved as a reference for manual rebuild, and your team keeps working in ConvertKit through the delta-pickup window that closes at cutover.

Object mapping
Each row shows how a Convertkit object lands in HighLevel, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Convertkit
Subscriber
HighLevel
Contact
1:1ConvertKit Subscribers map directly to HighLevel Contacts. Email address serves as the primary key for deduplication, preventing duplicate entries during import. Unsubscribed state in ConvertKit maps to the unsubscribed flag in HighLevel so consent records carry over correctly. All standard subscriber fields including name, email, and phone transfer directly. Custom metadata like creation timestamps and acquisition source are preserved as custom contact fields to maintain full contact history within HighLevel's CRM structure.
Convertkit
Tag
HighLevel
Tag
1:1ConvertKit tags replicate as HighLevel tags with identical names. Tags applied to multiple subscribers carry their association counts. If tags represent behavioral segments (e.g., 'purchased_2024'), those names are preserved verbatim for use in HighLevel Workflow conditions. HighLevel's tag-based segmentation can reference migrated tag names directly in Workflow triggers and conditions without requiring renaming or re-tagging of existing contacts.
Convertkit
Custom Field
HighLevel
Custom Field (Contact)
1:1Each ConvertKit custom field is created as a HighLevel custom contact field before import. Field label, key, and data type are matched — text to text, number to number, date to date, and pick-list values are mapped value-by-value. ConvertKit allows 140 custom fields maximum, which HighLevel's schema accommodates.
Convertkit
Form
HighLevel
Form
1:1ConvertKit forms are exported as a structured reference document including field list, embed code, and styling notes for recreation in HighLevel's form builder. The form logic — hidden fields, tag-on-submit rules, confirmation messages — is documented as a setup guide your HighLevel admin follows when rebuilding. We provide a field-by-field map so the rebuilt form captures the same subscriber data and triggers the same tag actions as the original ConvertKit form.
Convertkit
Landing Page
HighLevel
Funnel / Landing Page
1:1ConvertKit landing pages are exported as URLs and screenshot references. HighLevel's funnel builder uses a different structure, so pages must be rebuilt using HighLevel's drag-and-drop builder. We provide a page-by-page map noting which ConvertKit pages correspond to which HighLevel funnels.
Convertkit
Visual Automation
HighLevel
Workflow
1:1ConvertKit visual automations (entry points, conditions, actions, delays) cannot be transferred to HighLevel Workflows — the automation models are architecturally incompatible. We document every automation in a structured step-by-step format (trigger → condition → action) that maps directly to HighLevel Workflow triggers and actions for manual rebuild.
Convertkit
Sequence
HighLevel
Workflow (Email Sequence)
1:1ConvertKit sequences (email drip series with time-delay steps) are documented by step order, delay interval, and email content summary. HighLevel's email sequence is handled within its Workflow builder using time-delay actions and Send Email steps. We provide a sequence-to-workflow map your team uses to rebuild drip logic in HighLevel.
Convertkit
Broadcast
HighLevel
Campaign / Single Send
1:1ConvertKit broadcast history (past sends, subject lines, send dates) is preserved as reference metadata. HighLevel's Campaigns handle one-off sends prospectively. We export a broadcast log that your team uses to set up HighLevel campaigns that mirror your ConvertKit send cadence.
Convertkit
Product (Commerce)
HighLevel
Product / Opportunity Line Item
1:1ConvertKit products map to HighLevel Products when your setup includes order tracking. For simple digital products, we create HighLevel products linked to Opportunity line items. Complex subscription products may need a custom object if your order history includes recurring billing records.
Convertkit
Subscriber Email Engagement History
HighLevel
Custom Field (Contact)
1:1ConvertKit tracks per-subscriber open rate, click rate, and broadcast engagement counts natively. HighLevel's activity tracking starts fresh at go-live. We store your ConvertKit engagement history as a set of custom numeric fields on each contact (Last_Email_Open_Rate__c, Lifetime_Click_Rate__c) so historical data is accessible in HighLevel reports.
Convertkit
Creator Profile
HighLevel
Custom Field / External Reference
1:1ConvertKit's Creator Profile is a public-facing landing page displaying subscriber-facing content with no direct HighLevel equivalent. We export Creator Profile settings including page layout, branding elements, and linked subscriber content as a configuration reference document. Your team uses this reference to rebuild the Creator Profile as a HighLevel landing page, Funnel page, or external redirect link.
Convertkit
Subscription / Purchase History
HighLevel
Opportunity / Custom Object
1:1ConvertKit stores subscription and purchase records per subscriber. These map to HighLevel Opportunities if you use HighLevel's deal tracking, or to a custom Purchase History object if the record structure requires date, product, amount, and subscriber linkage. We surface the appropriate model in the migration plan.

Convertkit gotchas
Sequences export as content only, not logic
Free tier has no bulk export capability
Custom fields require recreation before import
Kit branding persists until toggled off
Subscriber count billing is real-time
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Audit ConvertKit data assets and document automation logic
FlitStack AI connects to your ConvertKit account via API using read-only credentials. We extract the full subscriber list (all fields including custom fields), complete tag definitions, form definitions, product catalog, purchase history, and engagement history exports. Simultaneously, we document every visual automation and sequence by step — entry trigger, each condition branch, each action (send email, add tag, delay, etc.), and delay intervals. This documentation becomes the rebuild reference your team uses in HighLevel's Workflow builder. No data is modified in ConvertKit during this phase.
Stand up HighLevel target schema before data arrives
Before any data moves, we create the HighLevel custom fields that correspond to your ConvertKit custom fields, sanitizing field keys to meet HighLevel's naming rules. Tags are set up in HighLevel with matching names. If your migration includes purchase history, we create the Opportunities pipeline and stage structure in HighLevel that mirrors your order volume segments. This schema-first approach ensures the import pipeline has valid destination fields for every incoming record and prevents partial loads due to missing field definitions.
Run a sample migration with field-level verification
A representative slice — typically 100–500 subscribers spanning your main tag categories and custom field types — migrates first. We generate a field-level diff report comparing each source field value against its destination field in HighLevel. You verify that tags appear correctly on contacts, custom field values populate the right fields, and email addresses are intact. Any mapping corrections (wrong pick-list value, custom field type mismatch) are resolved before the full run commits. This sample run also validates that HighLevel's rate limits are not triggered at your record volume.
Execute full migration with delta-pickup window
The full subscriber list, tag associations, custom field values, form references, product catalog, and purchase history load into HighLevel. A delta-pickup window — typically 24–48 hours — opens at the point when you confirm the sample migration results are acceptable. Any new subscribers who signed up in ConvertKit during the migration window are captured in the delta pass. FlitStack AI uses HighLevel's bulk CSV import endpoint for the primary load to minimize API call count and stay within rate limits. After the delta pass closes, we run a reconciliation report comparing total record counts by tag and custom field distribution against your ConvertKit pre-migration baseline.
Deliver automation documentation and post-migration support
The migration deliverable includes: (1) the complete field-mapping manifest with ConvertKit field keys and their HighLevel equivalents, (2) a structured visual automation rebuild guide listing every ConvertKit automation with step-by-step instructions for recreating each in HighLevel Workflows, (3) a form and landing page map showing which ConvertKit assets correspond to which HighLevel pages, and (4) a post-migration reconciliation report. FlitStack AI provides a 30-day post-migration support window during which any data discrepancies in the migrated records are corrected at no additional charge.
