What it does
Collecting email signups through a site form and then copying them into ConvertKit by hand is slow and easy to get wrong. This add-on removes that step. It works as an action inside JetFormBuilder, so a form submission can add the person straight to your ConvertKit lists. The plugin depends on JetFormBuilder, so it suits sites that already build their forms with it or plan to.
Setup happens in the form settings. You connect ConvertKit, then match each form field to a ConvertKit subscriber attribute, so names and other details land in the right place. Conditional logic lets you control when and how a subscriber is added based on what the visitor entered. You can attach the action to several forms across your site, and the form data you capture can help you segment your audience inside ConvertKit.
Best for
- Bloggers growing a ConvertKit newsletter list
- Marketers running segmented email campaigns
- Businesses using JetFormBuilder for site forms
Features
Automatic subscriber creation
Each form submission can add the visitor to your ConvertKit lists right away, so you no longer copy signups over by hand.
Custom field mapping
Match JetFormBuilder form fields to ConvertKit subscriber attributes so each contact arrives with the details you asked for on the form.
Conditional logic rules
Set conditions based on form input to decide when and how a subscriber is added, so different answers can lead to different outcomes.
Works with multiple forms
Attach the ConvertKit action to several JetFormBuilder forms across your site, such as a newsletter signup and a contact form.
Sync on submission
Subscriber data is sent to ConvertKit as soon as the form is submitted, keeping your lists current with new signups.
Data for segmentation
Information collected through your forms can be used to group subscribers in ConvertKit for more targeted email campaigns.
Built on JetFormBuilder
The action runs inside JetFormBuilder's form settings, so you configure it in the same place where you build and manage your forms.
Questions about ConvertKit Action
Do I need JetFormBuilder to use this plugin?
Yes. This is an add-on for JetFormBuilder and lists it as a dependency. The ConvertKit action is added to forms you build with JetFormBuilder, so that plugin needs to be active on your site.
Can I choose which form fields go to ConvertKit?
Yes. You map each form field to a ConvertKit subscriber attribute, so details like names or other answers are stored in the matching fields in ConvertKit rather than being lost or mixed up.
Can I add subscribers only when certain answers are given?
Yes. Conditional logic lets you set rules based on form input that control when and how a subscriber is added. For example, you could add people only when they tick a newsletter opt-in field.
Can I use it on more than one form?
Yes. The action can be attached to multiple JetFormBuilder forms across your site, so signups from different pages all flow into ConvertKit.
Is ConvertKit Action free?
The code of ConvertKit Action is licensed under the GPL, so anyone may use, change and share it. GPL Feast is a paid service: a plan or a single purchase gives you the download and automatic updates. The developer's own support, licence key and online services are not included.
Which version of ConvertKit Action is this?
Version 1.0.4, released Nov 5, 2025. New versions appear here when the developer publishes them, and members get them as automatic updates.
How do I update ConvertKit Action?
Install the free GPL Feast Updater on your site and connect it with your API key. It installs new versions of ConvertKit Action automatically and keeps a backup, so you can roll back.
