How to stop receiving emails in the new publication I do

Hey I'm having a problem with this forum,
When I post an answer on one of the threads, I receive emails when someone replies 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 find to change the "Alert preferences" and that does not help either.
Can anyone tell me how to stop receiving emails unless I subscribe to the thread?

Thank you
