Ninja Forms +
Kit

If you’re already using Kit (formerly ConvertKit) to run your email marketing, the Kit add-on for Ninja Forms closes the gap between your WordPress forms and your Kit account. Every submission goes straight into Kit as a new subscriber, complete with the data you need to segment, tag, and trigger the right sequences automatically.

This is different from Kit’s own WordPress plugin, which embeds Kit-hosted forms into your site. Ninja Forms builds WordPress-native forms you design yourself, then pushes the submission data into Kit. You get full control over form layout, field types, and conditional logic while Kit handles the email side.

With the Kit add-on for Ninja Forms, you can:

Key Features of the Kit Add-On

Subscriber email mapping

Kit requires an email address to save a new subscriber. The add-on connects your form’s email field directly to that Kit requirement so every submission creates a real subscriber record. No extra configuration needed once the field is mapped.

Kit form selection

Each submission is associated with a specific Kit form or landing page in your account. You choose which Kit form new subscribers are added to, keeping your Kit account organized the way you intend rather than lumping all form submissions into one place.

Sequence enrollment

The moment someone submits your form, they can be enrolled into a Kit email sequence automatically. Point the add-on at any sequence in your account, and new subscribers start receiving your onboarding flow, welcome series, or drip campaign without any manual steps. This is one of the most powerful things the integration does and it takes about ten seconds to configure.

Tag assignment

Apply Kit tags to new subscribers at the moment of submission. Use tags to record where a subscriber came from, what they expressed interest in, or which audience segment they belong to. Combined with Kit’s tag-based automations, this turns every form submission into a segmentation event.

Custom field mapping

Beyond email, you can map any form field to a Kit subscriber custom field. First name, phone number, company, or any custom field you’ve set up in your Kit account can all be populated at submission time. Your subscriber records in Kit stay complete from the first touch.

Multi-account support

Running multiple Kit accounts or routing different leads to different accounts? You can add multiple Kit actions to a single Ninja Forms form and use Ninja Forms’ Conditional Logic add-on to control which action fires based on the subscriber’s answers. Different audience segments go to different Kit accounts without any manual sorting.

Ninja Forms vs. Kit’s Own WordPress Plugin

Kit offers its own official WordPress plugin, and it’s worth being clear about what each one does. Kit’s plugin embeds Kit-hosted forms directly into your WordPress pages. Those forms are designed and managed inside Kit, not WordPress.

The Ninja Forms Kit add-on works differently. You build the form in WordPress using Ninja Forms’ drag-and-drop builder. You control every field, label, style, and layout. When someone submits the form, Ninja Forms sends the data to Kit as a new subscriber. The form lives on your site; Kit gets the subscriber data.

If you need a single opt-in box and Kit’s hosted form is fine, Kit’s plugin handles that well. If you need a multi-step form, conditional fields, file uploads, payment collection, or any combination of those on a single page, Ninja Forms builds the form and the Kit add-on moves the data where it needs to go.

How the Kit WordPress Integration Works

Setup takes a few minutes. Connect your Kit account by entering your V3 API key in the Ninja Forms settings panel. Once connected, your Kit forms, sequences, and tags all become available inside the Ninja Forms form builder.

From there, add a Kit action to any form, map the email field, choose a Kit form, and optionally select a sequence or tags. Save the form and it’s live. Every submission routes to Kit automatically, and Kit handles everything downstream from there.

Common Use Cases

• Trigger onboarding sequences from a lead magnet form: Someone downloads a guide, submits the form, and lands in your welcome sequence immediately. No delay, no manual import. Start with a pre-built lead generation template or build your own.
• Segment leads by interest at the point of signup: Use a dropdown or radio field to ask what a subscriber is interested in, then map that answer to a Kit tag so each subscriber enters the right nurture path.
• Route leads to the right Kit account for multi-brand operations: Use Conditional Logic to send form submissions to different Kit accounts based on which product or brand the subscriber selected.
• Collect richer subscriber data from a gated content form: Map name, company, and any custom fields to Kit subscriber records so your email personalization has more to work with from day one.
• Build a contact page that also grows your list: Add an opt-in checkbox to a standard contact form. When checked, the submission triggers the Kit action and adds the subscriber; when unchecked, it skips Kit entirely. Conditional Logic handles the branching.
• Run event registrations that populate a Kit sequence: Collect RSVP submissions and automatically enroll registrants into a pre-event drip sequence with reminders and follow-ups.
