<h4>What is Mailchimp?</h4>
Mailchimp is an award-winning marketing platform that allows you to send email campaigns to a list of subscribers. It is free for up to 500 contacts, which is why it is the newsletter-service of choice for thousands of small businesses across the globe.
If you are not yet using Mailchimp, <a href="https://mailchimp.com/signup" rel="nofollow ugc">creating an account is 100% free and only takes you about 30 seconds</a>.
<h3>3rd Party or External Services</h3>
The main goal of this plugin is to create a bridge between your WordPress site and Mailchimp. In order to accomplish this the plugin will initiate connections to the Mailchimp Marketing API through encrypted network connections. This is required to send and retrieve data between your site and Mailchimp, such as: templates, recently sent campaigns, name and size of subscriber lists and more.
You can learn more about the Mailchimp Marketing API <a href="https://mailchimp.com/developer/marketing/" rel="nofollow ugc">here</a>. 
Also take a look at the <a href="https://mailchimp.com/legal/" rel="nofollow ugc">Mailchimp Terms and Privacy Statements</a>.
This plugin does not collect any user data of your site’s visitors. However, you can choose to include Google Analytics tracking codes in the Landing Pages you import from Mailchimp to your WordPress site. Doing so will allow Google Analytics to collect all sorts of user data. This is optional and will only be enabled if you enter your Google Analytics Profile ID in the configuration.
