How to stop receiving emails on the new post I'm doing

Hey i have a problem with this forum,
When I post an answer on one of the threads, I receive emails when someone answers on the thread.

The email has the options of disable emails from this thread or disable all emails but both do not work well.

I tried to change the "Alert Preferences", which does not help either.
Can someone tell me how to stop receiving email if I do not subscribe to the thread?

Thank you
