e-Newsletter and Gravity Forms


I'm using Kleo WP theme and I want to use it with Gravity Forms, but I want to keep the same visual that the original template form as. The template http://seventhqueen.com/themes/kleo/e-learning-home/ is using the Mailchimp shortcode, I do not wish to use it with Mailchimp, I'll use the e-Newsletter plugin from wpmudev https://premium.wpmudev.org/project/e-newsletter/

Is there a way to keep the look and use Gravity Forms with e-Newsletter on it?

Thanks in advance
