Could you please answer a few questions:
1. What was the language you chose when you created your account?
2. Have you changed your preferred language at all since then or recently?
3. Is this the first time you’ve received an email in your non-preferred language, or has it always been sending emails in Russian?
4. To be clear, if you click on your profile picture, and under “Language”, you have “English” chosen, but are receiving Russian emails?
5. What is the language you have selected on https://help.twitch.tv?

Twitch should add feature for ' user prefer language for email notification by themselves. '
