Kit (formerly ConvertKit)

How to integrate Kit with Webflow

Kit offers multiple integration paths with Webflow, from simple embed codes to advanced API connections.

While Kit doesn't provide an official Webflow app, you can leverage third-party automation tools for workflow integration and embedded forms for quick setup. You can also build custom solutions using Kit and Webflow APIs for maximum control over subscriber data, automation triggers, and content synchronization.

Use third-party Marketplace apps

Since Kit doesn't offer an official Webflow app, Zapier serves as the primary integration bridge. Install Zapier from the Webflow Apps marketplace to connect form submissions directly to Kit subscribers, apply tags, and trigger automation sequences.

Key capabilities include:

• Automatic subscriber creation when visitors submit Webflow forms
• Tag application based on form fields or static values
• Custom field mapping to capture additional subscriber data
• Multi-step automations connecting Kit with 7,000+ other apps

For membership sites, Memberstack enables gated content with Kit integration. Members who sign up through Memberstack can automatically be added to Kit segments for targeted email campaigns.

Use code embeds and native features

Kit provides embeddable forms that integrate directly into Webflow using the Embed element. Generate your form in Kit, copy the JavaScript snippet, and paste it into a Webflow Embed component.

Form embedding process:

1. Create a form in Kit's visual builder
2. Navigate to the Embed section and copy the code
3. Add an Embed element in Webflow where you want the form
4. Paste the Kit code and publish

Landing page integration works similarly. Host landing pages on Kit's subdomain (yoursite.kit.com) and link to them from your Webflow navigation. This approach leverages Kit's conversion-optimized templates without complex integration.

For dynamic recommendations, enable Creator Network on your Kit forms to display peer creator suggestions, boosting subscriber growth through cross-promotion.

Build with Webflow and Kit APIs

Direct API integration unlocks advanced capabilities beyond basic form submissions, enabling real-time subscriber synchronization, automated content publishing, and sophisticated segmentation based on user behavior. This approach requires server-side implementation but provides complete control over data flow and automation logic.

Key benefits include:

• Bi-directional data sync between Webflow CMS and Kit
• Event-driven automations triggered by site interactions
• Bulk operations for migrating existing subscribers
• Custom authentication flows for membership sites

Sync Webflow forms with Kit subscribers

Create a seamless connection between Webflow form submissions and Kit subscriber lists using the subscribers endpoint:

1. Configure webhooks: Set up Webflow form notifications to trigger your server endpoint
2. Process submissions: Extract form data and map fields to Kit subscriber properties
3. Create subscribers: Use POST /v4/subscribers with email and optional metadata
4. Apply tags: Segment subscribers using PUT /v4/tags/:tag_id/subscribers/:id based on form responses

The bulk subscribers endpoint handles up to 100 simultaneous operations for high-volume migrations.

Automate email campaigns from CMS updates

Trigger Kit broadcasts when publishing new content in Webflow CMS:

1. Monitor CMS changes: Use Webflow webhooks or polling to detect new items
2. Generate email content: Pull CMS data including titles, excerpts, and images
3. Create broadcasts: Use POST /v4/broadcasts to draft emails
4. Schedule delivery: Set published_at for optimal send times

This workflow ensures subscribers receive updates about new blog posts, products, or resources automatically.

Build advanced segmentation workflows

Leverage Kit's tagging system to create sophisticated audience segments based on Webflow interactions:

1. Track user behavior: Monitor page visits, downloads, or purchases
2. Create dynamic tags: Use POST /v4/tags for behavior-based labels
3. Update subscriber profiles: Apply tags via API when users complete actions
4. Trigger automations: Kit sequences activate based on tag applications

The custom fields API enables storing additional data like quiz scores or preferences from Webflow interactions.

What you can build

Integrating Kit with Webflow opens possibilities for sophisticated marketing systems and creator businesses.

• Newsletter signup systems: Embed Kit forms throughout your Webflow site with exit-intent popups, inline blog CTAs, and dedicated landing pages that feed into segmented email sequences
• Course enrollment funnels: Build sales pages in Webflow that connect to Kit for automated course delivery, drip content sequences, and student progress tracking through tags
• Membership communities: Gate premium content using Webflow's member areas while Kit handles email onboarding, renewal reminders, and exclusive subscriber benefits
• E-commerce email automation: Sync Webflow store purchases with Kit to trigger post-purchase sequences, product recommendations, and customer win-back campaigns
