WP Chimp


WP Chimp provides the ability to add a MailChimp subscription form to your post and page content and in the Widget area. The plugin also registers a custom Gutenberg Block allowing you to add and preview the subscription form immediately within the WordPress content editor.

This plugin focuses on simplicity, user experience, and speed. We ensure to provide seamless integration to MailChimp services, ease of use with an interface that complies with WordPress design guidelines, and that it would work at scale.
