ConvertKit makes it easy to capture more leads, sell more products and send targeted email marketing by easily embedding email capture forms anywhere on your WordPress web site.

Main Features

  • Design subscription forms in ConvertKit, automatically appending them to any WordPress post or page, or displaying forms within your WordPress content using the supplied Gutenberg block and shortcode options
  • Build landing pages in ConvertKit, and display them on a WordPress page
  • List past email broadcasts on your WordPress site


Design forms in ConvertKit, choosing from a variety of designs, customisable to your branding.

Sign up forms can be configured to:
– Send free content, such as a PDF
– Display when the user is about to leave the page
– Subscribe to an email newsletter, with powerful tagging and segmentation options

Embedding ConvertKit forms on your WordPress web site with the ConvertKit Plugin is quick and simple:

  • Choose a default form to be displayed below each individual Post Type (Pages, Posts and other public Post Types, such as WooCommerce Products)
  • Choose a specific form to be dispalyed below a specific Page, Post or custom post type
  • Turn off form embedding at both site wide and/or individual Page/Post level

For greater control, ConvertKit forms can be displayed in specific sections of your WordPress site’s content, sidebars and footers by:

  • Using the ConvertKit Forms block in Gutenberg
  • Using the [convertkit] shortcode in the Classic Editor

Landing Pages

Embed landing pages designed in ConvertKit on your WordPress web site, choosing from a variety of designs, customisable to your branding.

Create or edit a WordPress Page, choose the ConvertKit landing page from the ConvertKit meta box settings to display, and you’re set.


Use ConvertKit’s email marketing feature to send newsletters to subscribers and leads.

Embed existing email marketing newsletters on your WordPress web site, ensuring visitors never miss newsletter content, by:

  • Using the ConvertKit Broadcasts block in Gutenberg
  • Using the [convertkit_broadcasts] shortcode in the Classic Editor
