I am currently using the Jetpack and WPML to enable posts in 2 languages on my website. I translated the subscription widget in Spanish, however when Spanish users subscribe on my site, the emails are sent to them in English such as "Confirm subscription request" and "New post" and the content is entirely in English. (I think probably because of default settings in Jetpack.) The problem is that most of my Spanish subscribers won't be able to understand the confirm subscription request and they won't click on the "Confirm follow" button if they don't understand what it means. Therefore I wonder if it is possible for the Jetpack plug-in to send/develop these standard messages in Spanish.
