I once got an email in another language but happened to recognize it since my grandmother used it regularly. So I ran it through one of those translator services, and it was pretty mundane 'how are you and your kid's type stuff.

Ended up writing back via translator text, turned out they already spoke English though. Seems her brother has the same name and email as me but with a different provider and she just mixed up the domain.

I occasionally get random spam that I think was meant for him since it's all localized.
