Unwanted spammy email in unspecified language

I’m on vacation in Korea. I just received an ad email from lingQ in Korean. It was addressed to Korean (people from Korea) members. I believe I have elected never to receive any emails from lingQ in my preferences, so could someone explain what’s going on.

Hi Wulfgar,
Can you please forward us that email to support(at)lingq.com? Thanks!
