update: Looks like I got a lucky freebie, this email came ~2.5 hours later.

"Hi "Blockstock",
The previous email you were sent from Stake was sent in Russian, which was not intended.

Stake is a global company & a lot of communications are localized.

Luckily, the bonus sent in that email is valid for you and only you, so please feel free to claim that bonus.

Rest assured this was sent by us and is a legitimate email. We apologize for the inconvenience and we hope you’re having a great new year."


// Question answered, thank you Stake for being the most generous casino!
