I happened to look in my Gmail spam folder and by chance I noticed a very important invoice from a well-known worldwide organisation I have recently done business with.
It's a legitimate invoice for services they had genuinely done for me, from their regular, official email account.
I found Gmail's reason for marking it as spam both shocking and worrying. I've lost the original exact wording, but it was something like:
We have marked this email as spam because it is in a language you don't normally use. Read more
This wasn't even true: the email had a standard legal notice about the contents of the attached invoice in 9 different languages - including English which is the language I normally use, plus 8 other languages.
Maybe it's unusual in the corner of the world where Google is based, but I often do business with organisations who have international customers or who are themselves international. It's not unusual for me to send or receive emails that include sections in another language.
When this happens, I don't want it falsely marked as spam (especially when it has all the hallmarks of a legitimate email).
But I can't find any way to turn this feature off, or to reconfigure it. The only link was to a page that mentions "some" of the reasons messages are marked as junk, but not this one.
How can I stop Gmail blocking multi-lingual emails that have no other hallmarks of being spam?
