Contact Form 7 integration with MailChimp

Hi All,

We have a WordPress website that has three different CF7 forms where visitors leave their contact information and are redirected to a thank you page where they can download a particular e-book.

What we would like to do is to add all these contacts into our MailChimp account and send them periodical emails. After searching online, we couldn’t find specific information, other than installing additional plugins and/or using Mailchimp forms. We like CF7 and don’t want to replace it.

My question is: Can we connect CF7 with Mailchimp API directly so that whenever a visitor leaves their contact info on our forms, they would be automatically added to our Mailchimp list?

Any help or guidance would be very much appreciated.

Thanks.
