The blog subscription shortcode displays a subscription box on the website front-end. Here’s how it looks for logged-in visitors:

and for non-logged-in visitors:

- Open your page or post editor.
- Insert a shortcode block.
- Paste
[blog_subscription_form]
into the box. - Save or publish your page.
The following arguments can be added to the shortcode to customize how it looks:

Specify the title of the form for visitors not already subscribed to your site
Default: Follow Blog via Email
Example: [blog_subscription_form title="Subscribe"]
title_following

Default: You are following this blog
Example: [blog_subscription_form title_following="You are already subscribed"]
subscribe_text
