I wrote this plug-in mostly as an attempt to learn more about creating WordPress Plug-ins, but I think it is potentially useful for certain folks and so I am releasing it as an open-source, unsupported piece of software. I hope you enjoy it.
The goal of the plug-in is to help a WordPress Site Administrator integrate a MailChimp mailing list into the WordPress site. Once the plug-in is installed, you must provide a MailChimp.com APIKey, then select a list to enroll your visitors to.
The default widget is practical, but not very pretty. Basically, it includes a typical widget layout containing three input fields, one hidden field to track the page URL, and a submit button. The HTML for the widget can be customized to fit your site and WordPress theme. If you choose to do this, please don’t try to change the input fields’ NAME or ID attributes. It won’t work if you change these.

Connect Contact Form 7 and Mailchimp

I had an issue, turned out it was related to Mailchimp!
They were tireless in helping out, thanks a lot!!

Awesome Support!

I've used the free version of this plugin many times and works great. I needed the GDPR feature so I purchased the Pro version. That didn't work so I've reached out to support multiple times with no response! There's no such thing as their "LIVE" chat feature, just a contact form. Seems like they're just ghosting everyone!

No support for paying users


Fix your global CSS on the admin panel, its interfering with other plugins CSS. You are display: none; other plugins elements. Come on man, its basic practice to use custom classnames.
