Email Spam Filtering and Sorting by Unopened

Can someone tell me how to get the spam filtering to actually work???  I am so frustrated by the amount of spam I get and my inability to find the right settling to stop the spam that I am considering changing email accounts.

I also cannot seem to find how to sort my mail so that I only see messages that are unopened.  can someone help guide me to or provide instructions.  If these sound like geezer questions, they are.

The best you can do is add filters for big stuff.  and keep marking as Spam any actual spam.  Note don't mark as spam legitimate email from companies you do business with but don't really want to see, filter those if you don't want them.
