Why Do People use Spam Filter Email Boxes?

The othr day I was out doing some affiliate marketing promotion to build a mailing list. I noticed I recevied and email from a spam filter. It says

I was thinking to myself, why would someone need to use a spam filter on their email box? I can understand they don’t want and spam but why not just have a junk email. Even the odd spam gets through.

Personally myself, I just created a bunch of email filters to filter my emal. Even gmail has a great system to create filters and you could even use it to reditect your mail to your good email.  Even if you own a server, you can create filters on that email too.

Filtering your email is fairly simple once you know where you need to goto change things. Then you won’t have to goto a spam filtering service, you can just allow the mail you want without people getting angered at you.
