The Official MailerLite Sign Up Form plugin makes it easy to grow your newsletter subscriber list. Use the plugin to add newsletter sign up form to your WordPress blog or website and automatically integrate it with your MailerLite account.
How it works
1. Log in to your WordPress Admin or get access to your blog FTP storage.
2. You either download the plugin using the wordpress plugin editor or download it manually and place it /wp-content/plugins/ folder.
3. After you downloaded or placed the plugin, all you need to do is to active it in the WordPress admin panel.
Once you activate the plugin, you'll be able to select and add any of webforms you have in your MailerLite account or create a new webform. Place the webform in the sidebar using widget or put it anywhere in your post with a shortcode.
