I had someone take over an old netflix account of mine, they said it's common for people in other countries to take control of a US based netflix account and even change the payment method to theirs. I'm guessing they get different content with a US based account.
More likely someone created a trial account using that email address with a fake/stolen payment method.
I recently got an unexpected netflix marketing email too.
It has to be part of one of the leaks.
Most probably because of this: https://securitytoday.com/articles/2018/04/03/under-armor-ad...
Test your email here if it was leaked: https://haveibeenpwned.com/
Also from the email it seems someone created an account. This is not a marketing email
