This plugin registers a custom WordPress widget called Mailchimp by ProteusThemes. This widget will allow you to connect to your Mailchimp account with your API key and you will be able to select the list you want your visitors to subscribe to.
This widget can be used for all sorts of things, like: newsletter, lead capture, email sequence, and much more!
The Widget will output an email input field and a submit button, that’s all you need to capture your visitor’s email address. Main idea behind this plugin is that’s easy and simple to use.
