Email advertising

depending on your email service provider you can block their email addresses in mail options. If you are getting lots from one company with different email addresses but the same domain name then just block that bit and it will block anything from them but be careful and don’t block from anything like yahoo.com using only the domain as it will block email from your friends too.

Yeah, so? You are getting spam, like all the rest of us. If you don’t open and read this junk, you’ll begin to cut down on the amount you get. But as long as you open and read them, or try to unsubscribe from them, your spam load will increase. Opening this crap just sends your real email address to the spammers, then they collect and sell that info to other spammers. Whoops! Up goes your spam load.
If you use Yahoo mail, you were given a spam button. Use it. On every piece of mail from someone you don’t know. Unopened.

With Yahoo you by the paid email service.
