Overview

What this migration involves

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.

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

HighLevel logo

HighLevel

What's pulling them in

  • Agencies choose HighLevel to consolidate CRM, email, SMS, scheduling, and funnels into one subscription, eliminating monthly bills for five to ten separate SaaS tools they previously stitched together.
  • The flat-rate pricing model bills per sub-account rather than per contact, so growing a contact database from 1,000 to 100,000 records does not trigger a billing surprise—a common pain point avoided by migrating customers.
  • White-label and sub-account capabilities let agencies resell HighLevel access to their own clients, turning a software cost center into a recurring revenue stream that justifies the subscription.
  • The platform ships a 14-day free trial with no credit card required, giving teams a low-friction entry point to validate fit before committing to the $97/month Starter tier.
  • Marketing agencies managing multiple client accounts use sub-accounts to maintain data isolation per client while operating under a single agency billing relationship with HighLevel.

Object mapping

How Convertkit objects map to HighLevel

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

maps to

HighLevel

Contact

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Tag

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Custom Field (Contact)

1:1
Fully supported

Each 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

maps to

HighLevel

Form

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Funnel / Landing Page

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Workflow

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Workflow (Email Sequence)

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Campaign / Single Send

1:1
Fully supported

ConvertKit 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)

maps to

HighLevel

Product / Opportunity Line Item

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Custom Field (Contact)

1:1
Fully supported

ConvertKit 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

maps to

HighLevel

Custom Field / External Reference

1:1
Mapping required

ConvertKit'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

maps to

HighLevel

Opportunity / Custom Object

1:1
Fully supported

ConvertKit 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.

Pair-specific challenges

  • Visual automations do not migrate — they require a structured rebuild in HighLevel's Workflow builder

    ConvertKit's visual automation canvas encodes entry points, conditions, branches, delays, and email-send actions as a saved graph. HighLevel's Workflow engine uses trigger-action chains that operate on a fundamentally different execution model. There is no import path between the two automation systems — the logic cannot be transferred automatically. FlitStack AI documents every ConvertKit visual automation in a step-by-step format (trigger type, each condition, each action, each delay interval) that maps directly to HighLevel Workflow triggers and actions. Your team or a HighLevel admin uses that document to rebuild the automation in HighLevel's Workflow builder. This is a manual step — budget time for it in your migration plan.

  • HighLevel's API rate limits cap bulk import throughput on large subscriber lists

    HighLevel's API 2.0 enforces 200,000 requests per day per sub-account and 100 requests per 10-second burst limit. For a migration with 50,000+ subscribers and their field data, the total API call volume (contacts + custom fields + tags) can approach or exceed daily limits depending on your sub-account tier. FlitStack AI mitigates this by using HighLevel's bulk CSV import endpoint for the primary contact load (one request per batch) rather than individual record API calls, reserving direct API writes for custom field correction passes. For very large lists, we schedule migration runs outside business hours to stay within rate limit windows and use a retry queue for any 429 responses.

  • ConvertKit's engagement activity history does not carry into HighLevel's native activity timeline

    ConvertKit tracks per-subscriber open counts, click counts, and broadcast-level engagement as native data you can export at the contact level. HighLevel's activity timeline is prospective — it records actions taken within HighLevel (emails sent, tasks completed, notes logged) but does not ingest historical engagement data from external platforms. This means your ConvertKit open/click rates will not appear in HighLevel's built-in activity feed. FlitStack AI stores ConvertKit engagement history as custom numeric fields on each contact (Lifetime_Open_Rate__c, Lifetime_Click_Rate__c, Broadcast_Send_Count__c). These fields are queryable in HighLevel reports and usable in Workflow conditions, but they appear as static custom fields rather than in the chronological activity stream.

  • ConvertKit's custom field key format requires sanitization for HighLevel's field-naming rules

    ConvertKit generates custom field keys in the format ck_field_1_my_field_name, using underscores and numeric prefixes. HighLevel custom field keys must be alphanumeric without reserved prefixes. When we create HighLevel custom fields during migration setup, each ConvertKit field key is sanitized (numeric prefix stripped, spaces converted to underscores, invalid characters removed) to produce a valid HighLevel field key. If your team has integrations or Zapier workflows that reference ConvertKit field keys by name, those references will need to be updated to the new HighLevel field keys after migration. We provide a field-key mapping table in the migration report that lists every original ConvertKit key alongside its new HighLevel equivalent.

  • ConvertKit's creator-tier pricing structure means engagement segments may not translate directly to HighLevel's tag-based segmentation

    ConvertKit subscribers are tagged with behavioral and source labels that drive segmentation in sequences and broadcasts. These tags migrate directly as HighLevel tags, but the automation logic that used those tags — sending to a segment of 'purchased_2024 AND opened_3_or_more' — is an automation, not data, and must be rebuilt. Additionally, ConvertKit's subscriber scoring (Creator Pro feature) is a numeric score per contact. HighLevel does not have a native subscriber scoring equivalent, so the numeric score migrates as a custom field (Subscriber_Score__c) and can be used in HighLevel Workflow conditions for routing, but the automated score-recalculation logic from ConvertKit requires a separate HighLevel workflow to recreate.

Migration approach

Six steps for a successful Convertkit to HighLevel data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Destination

Strengths

  • Consolidates CRM, marketing automation, email, SMS, scheduling, and funnels into one platform at a predictable flat monthly rate.
  • Supports unlimited contacts and unlimited users on all paid tiers, removing per-record billing anxiety as databases grow.
  • Offers white-label and sub-account capabilities that let agencies resell access and manage multiple client environments under one billing relationship.
  • Includes built-in review management, reputation monitoring, and AI agents as native features rather than third-party add-ons.
  • Exports Contacts and Companies via a scalable async bulk CSV system that handles multi-million-row datasets without blocking the UI.

Weaknesses

  • The breadth of features creates a steep learning curve; advanced automations and Workflow configuration require significant time investment that smaller teams may not recover.
  • The platform charges usage-based fees for telecommunications and AI features that are not included in the base subscription, leading to bill surprises.
  • Recurring user reports on Reddit and G2 describe bugs, errors, and slow support response times that disrupt live marketing and sales operations.
  • Sub-account architecture, while powerful for agencies, adds migration complexity when identifying which client data lives in which isolated environment.
  • The platform is designed for agencies and SMBs; larger enterprises requiring deep reporting, custom objects at scale, or complex role-based access may outgrow its capabilities.

A data-only migration (subscribers, custom fields, tags, products) for under 25,000 subscribers typically completes in 48–96 hours of clock time once access is granted. The automation documentation phase runs in parallel and takes 3–7 days depending on the number of visual automations and sequences. Complex migrations with 100,000+ subscribers, 50+ custom fields, and purchase history that requires opportunity mapping extend to 5–14 days. The longest single phase is typically the schema setup in HighLevel (creating custom fields and tags) combined with the sample migration verification step.
