Hey vivipapaliaga,
Thanks for stopping by and posting in the support forum. When setting up a multilingual WordPress site, it would require the use of some additional Plugins to make the site adapt to the language of the subscriber that visits that page. While our plugin does include various translations, it would be up to such a plugin to changes the displayed language based on the browser used to visit the page. I would recommend checking out this resource from WordPress for additional information on getting started on a multilingual site: http://codex.wordpress.org/Multilingual_WordPress
Thanks again for posting. If there are any other questions we can help out with regarding the plugin, please feel free to stop back by. Have a great day!

Hey vivipapaliaga,
Thanks for posting again. Because the translation plugin or add-on would be responsible for changing the language of the page and the MailChimp list subscribe form plugin, we wouldn’t really be the best resource for translating the page for a multilingual site. In this case, I would recommend reaching out to the support team for WPML here: http://wpml.org/forums/forum/english-support/ for more information on translating other WordPress plugins.
Thanks again for swinging by. Please feel free to contact us with any other questions about the form plugin. Have a great day!
