Showing a sign-up form in your WordPress posts or pages is as easy as copy-pasting the following shortcode in your post editor.
Example: Show default form
[mc4wp_form]
The shortcode takes an optional id argument which controls which form you would like to show.
You only need to supply this argument if you are using Mailchimp for WordPress Premium, since creating more than one form is one of our premium features.
Example: Showing form with ID 100
[mc4wp_form id="100"]
You can use the same shortcode multiple times to render the same from more than once. When viewing the post or page on your site, the sign-up form will be showing instead of the shortcode.
The form shortcode accepts several other optional arguments.
