The Newsletter Subscribe extension connects Blocksy with supported email marketing services, allowing visitors to subscribe directly from your website.
Subscription forms can be added using the dedicated Newsletter block, automatically displayed on Single Posts, or inserted anywhere that supports shortcodes.

Newsletter Subscribe supports the following email marketing services:
- Mailchimp – available with Blocksy Free.

Getting Started
To activate and configure Newsletter Subscribe:
- Navigate to WordPress Dashboard → Blocksy → Extensions.
- Locate and activate the Newsletter Subscribe extension.
- Open the extension’s settings and select your newsletter provider.
- Enter the credentials required by that provider, such as an API key, account identifier or other connection details.
- Select the list or audience that should receive new subscribers where the chosen provider supports this option.

The exact connection settings depend on the selected provider. Once the integration has been configured successfully, the same provider connection can be used by Blocksy’s different Newsletter Subscribe form implementations.
Double Opt-In
Supported providers can use a double opt-in subscription flow, where the visitor must confirm their email address before being added as an active subscriber. Availability depends on the newsletter provider and its integration.
Newsletter Block
The dedicated Newsletter block provides the most flexible way to place a subscription form inside content created with the WordPress block editor.
You can add it to posts, pages, supported Custom Post Types, Content Blocks and other areas where the block editor is available. The block includes its own layout, content and design controls while using the provider configured through the Newsletter Subscribe extension.
Individual Newsletter blocks can also target a specific provider list instead of relying on the extension’s default list.
For the complete set of block options, see the Newsletter block documentation.
Single Post Subscribe Form
Blocksy can automatically display a newsletter subscription form as part of your Single Post layout, without requiring you to insert a block into every article individually.
To enable it:
- Open Customiser → Single Posts.
- Locate the Subscribe Form module.
- Enable the module.
- Configure its content, form options and design settings as needed.

The form uses the provider configured through the Newsletter Subscribe extension, while its presentation can be customised specifically for the Single Post layout.
Newsletter Subscribe Shortcode
The Newsletter Subscribe form can also be inserted using a shortcode. This is useful in locations where the Newsletter block is not available, including compatible widgets, page builders and other shortcode-enabled areas.
Basic Usage

Without additional arguments, the shortcode uses the default configuration from the Newsletter Subscribe extension.
