Hi Albert,
Thanks for stopping by.

With regards to your question, our developers are currently working on the multiple language translation feature so that our users can translate the emails they create into about 108+ languages, and the Spanish language is one of them. Once we're done, we're going to roll it out for all our users.
But in the meantime, we only support the English language.
Not sure how long the deal will last yet, (we haven't reached an agreement on that with AppSumo) but we're planning to stack our codes and increase the price soon.
