The Newsletter Subscribe extension in Blocksy makes it effortless to grow your email list by capturing leads directly on your website. It seamlessly integrates with the most popular newsletter services, giving you a powerful tool to engage with your visitors and build lasting relationships.
This extension offers multiple ways to display subscription forms throughout your site – at the end of posts, via a dedicated Gutenberg block, or even using a flexible shortcode. No matter how you choose to implement it, the setup is straightforward and the results are immediate.
Provider Support
With Blocksy Pro, you gain access to integrations with MailerLite, MailPoet, Brevo, ConvertKit, Active Campaign, EmailOctopus, Klaviyo, FluentCRM, and Campaign Monitor. Blocksy Free users can still take advantage of the powerful Mailchimp integration.
Activating the Extension
To enable the Newsletter Subscribe extension, follow these steps:
- Open your WordPress Dashboard.
- Click Blocksy in the sidebar.
- Go to the Extensions tab.
- Locate the Newsletter Subscribe extension.
- Toggle it on.
Once activated, you’ll need to configure your newsletter provider by entering your credentials. Simply select your provider from the list and add the required details, such as your API key. This one-time setup connects your forms to your email service provider.

Newsletter Gutenberg Block
The extension includes a dedicated Newsletter Gutenberg block that can be added anywhere the Gutenberg editor is available – pages, posts, or any custom post types.
This block gives you full design control and makes it simple to place subscription forms exactly where they’ll be most effective. For detailed information on configuring and styling this block, refer to our dedicated article: Newsletter block.
Newsletter Subscribe Module
You can also display the Newsletter Subscribe form automatically at the end of your Single Posts. This placement is ideal for capturing readers who’ve just finished engaging with your content.
To enable this feature:
- Navigate to Customiser → Single Posts.
- Locate the Subscribe Form option.
- Toggle it on.
- Explore the module’s settings to customize the form’s appearance and behavior.
This module inherits your extension settings but allows for post-specific customisation when needed.

Newsletter Subscribe Shortcode
For maximum flexibility, the Newsletter Subscribe extension provides a shortcode that can be inserted anywhere on your website – sidebars, custom widgets, or even within page builder layouts.
