It happened to me last year or something. Reset your password and it’ll be fine. It was probably leaked.

Or do the smart thing and stay here instead. :)

As a general rule of precaution, don’t follow links in the email. Instead go to the website directly, maybe from a private or incognito instance, and reset it directly. If the email is valid, you’re doing the same thing and if it wasn’t you aren’t drawing attention to anyone else.
