I often use multiple languages in a single email, or want to write an entire email in another language without auto-correct or spellcheck to constantly freak out, so allow a set of languages for a user, with spell-check etc. covering. As a Swiss Co. you should understand how English, German, Italian and French could easily end up combined somehow. Let users pick, say 3 or 4 languages. I believe Google has this already!
