User Registration MailChimp
With our User Registration MailChimp add-on, you can easily add subscribers to your MailChimp account as they register on your site. Moreover, there are more options that the add-on offers that you cannot miss. After you integrate your MailChimp account using the add-on, you can add the users to your MailChimp list directly after they register on your site. So, you can create a MailChimp registration form to automatically add subscribers. You need to install the WPEverest User Registration plugin, before installing this add-on.
