email filter not enough

Please, please help me. I am getting at least 1-2 dozen emails everyday that indicate no addresses and only have subject lines such as Disney Trip, Mattress Option, Rent to Own Property, etc., etc..

I have copied the address' and gone into my Mail Preferences, selected a Rule that if Any/From ends with (the copied email) then Delete the Message. It will eliminate today's batch of emails, but dozens more will come with the next download. My Rules List is now about 2 dozen rules long. It doesn'treally eliminate the problem.

Is there some other approach I can take to get rid of this problem? I am not that savvy with the computer configuration, so if you can please explain to me in real simple lay terms, I would appreciate it.

Is my best solution tochange my email address?

Thanks in advance.
