Should I be concerned with how Google treats my signal globally? Honest question. If I were Google I'd recognize that how the email is stopped before getting to a user's inbox probably won't matter to them and factor that into how the unsubscribe and mark as spam buttons work. As a user I expect my treatment of "mark as spam" on a GitHub notification to be more heavily weighted in my personal spam algorithm than the global spam algorithm.

I don't think anyone outside Google knows the exact details, but GMail clearly calculates a global reputation score for each sender that is influenced by what percentage of recipients mark its messages as spam. Then there's some additional weighting on top of that based on your personal actions.

Additionally most reputable email senders have a "feedback loop" set up with Google, Hotmail, and Yahoo where clicking that Report Spam button actually passes your email address back to the sender's email system. For example if you click Report Spam on one of our email newsletters in GMail, we will flag your record in our database and not send you any more messages even if you specifically sign up for a newsletter in the future. (Please don't test this.)
