There was a time I used to lose the time of my life sending emails to those deceitful marketers who - despite strict laws - Still do not give you an unsubscribe option in their newsletters, and requesting them to Unsubscribe me.

I don’t bother any more, and I recommend you don’t do that either.

There is an easier way if you have your own website with Control Panel.
Simply logon to your Control Panel and just put an email Filter on that particular email address. You can either discard it or bounce back.

I am using Cpanel so I go to Mail -> Email Filtering -> Add Filter -> I enter the info needed -> then just hit the Activate button, and that’s it!

Usually I just put straight discard on the particular email address as there is enough of unnecessary traffic on the Net anyway, so I never even see that email message again.

Here are some examples of the annoying publishers without any Unsubscribe option in their emails:

$header_from: contains “@jamesmaduk.com” Discard
$message_headers contains “tyler@submitsolutions.com” Discard
$message_headers contains “administrator@affiliate-marketing-school.com”

So Save yourself time and aggravation, just put a discard filter on those ‘unreachable marketers’ and let Them lose their time and resources sending useless emails into the black-hole of cyberspace.
