Hi Vics,
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 100+ languages, and the French language is one of them. Once we're done, we're going to roll it out for all our users.

Hi Mario,
The languages you mentioned will be included once our translate feature goes Live
