Worlds spoilers in my email?

I just received a marketing email from Riot for the Worlds finals match. The subject of the email had the names of the two finalist teams. I've been catching up on the semifinals VODs, diligently avoiding spoilers (these boards, the LoL subreddit, basically anything online that would indicate who won the semifinals matches), so it was more than a bit of a bummer to get this delivered right to my inbox :/
