I’ve spent a lot of time looking for Plugins that allow you to easily format Mailchimp for free. This one does the trick!

Once I installed and connected the plugin to my account, it kind of
got a hint of automatic service. It allowed to choose the list, the
form and got me straight to the form creation. This is how nice people save your time.
Plus it included my theme styling option, which is cool as well.

I have been using a form plugin and was trying to integrate it with MailChimp and it turned out it takes a lot of integration to make those two work together. I was sooo disappointed. And I came across this plugin, which made my recovery way faster. In just a few minutes I created a form which got automatically integrated with my MailChimp forms. Thanks God!
