How to add MailChimp subscription form on your website
MailChimp subscription forms like shown on the demo is done with a MailChimp plugin: https://wordpress.org/plugins/mailchimp-for-wp/
You’ll just need to install & activate the plugin, then connect it to your MailChimp account. Once activated, the plugin will add a new menu item in your WP Dashboard called MailChimp for WP. Click on, and follow the steps. The first one will be to set your MailChimp API settings, then create your form. We use a very basic form on our demos which you can use as well:
<p><input type="email" name="EMAIL" placeholder="Your email address" required /></p>
<p><input type="submit" value="Sign up" /></p>
Save your form settings and make sure you check out the other plugin settings, and connect it to a certain Newsletter List.
How to show it on the page
From here on, it’s a simple thing. You can either use the sidebars in the post option (left or right) and add the widget in there. Adding a new widget is simple.
If you want to use the newsletter subscription form in the layout builder, it’s quite simple as well. We would recommend to create a custom sidebar and show it using the builder.
