Description
The ConvertKit addon connects WS Form forms to your account on the email marketing platform, sending each submission as a new subscriber to forms, sequences, or tags configured in the panel. The integration maps default and custom fields, triggers actions on the form save or submit, and automatically generates a WS Form ready from any existing ConvertKit form, with optional opt-in for GDPR compliance.
Main Features of ConvertKit
- Automatic form generation
Creates a complete WS Form from any existing ConvertKit form in one click. - Mapping of default and custom fields
Links WS Form fields to native and custom fields of ConvertKit. - Tag mapping by choice
Connects Select, Checkbox, and Radio field types to specific tag IDs in ConvertKit. - Trigger on save or submit
Allows the action to run when saving the form, submitting, or on both events. - Direct tag assignment
Applies fixed tags to the new subscriber without relying on a selectable field in the form.
Benefits of ConvertKit
- Lead capture without manual export
Each form submission becomes a subscriber directly in ConvertKit, with no CSV in between. - Segmentation at registration
Tags and sequences applied on submission already organize the list by interest or source. - GDPR compliance
An optional opt-in checkbox documents consent for those who subscribe to the list. - Less initial setup time
Automatic generation eliminates the effort to build and map each field from scratch.
Who is ConvertKit for?
- Those who use ConvertKit for newsletters and want to feed the list from forms on their own WordPress site.
- Targeted at those who capture leads on landing pages and need to segment by tag or sequence at the time of registration.
- For those who maintain sign-up forms for courses, e-books, or webinars and want to send contacts directly to email automation sequences.
How to download ConvertKit
The ConvertKit addon is available for download here on Ultrapack. After downloading the .zip file, install it in Plugins > Add New, Upload Plugin, select the .zip, and activate. Have WS Form installed first, since the integration depends on it to run; the ConvertKit API key is configured in the WS Form options.
By combining automatic form generation and granular tag mapping, the addon bridges lead capture in WordPress and email automation in just a few clicks. No CSV export or intermediaries like Zapier in the flow: each submission arrives at ConvertKit already segmented, ready to enter the proper sequence and trigger the corresponding email.
