Every day I get hundreds of email spam in my aol and yahoo email accounts. I cannot block the emails unless I enter the full email address of the sender. The problem is that the email spammers always change their sending address. In order to block the worst offenders of email spam I would have to enter a new email address in my email filter every time I got one of their spams.
What all email providers should do is not force users to enter a full email address to block spam emails but allow us to enter a simple SUBJECT or TITLE to block spam emails. Like "Camp LeJeune" Or "McAfee". Or "penis".
btw, advertisers who pay spamming/email marketing companies to send out unsolicited emails, i.e. spam, are dumb. Nobody in their right mind opens the spam emails they receive, they just delete them. And many/most of those emails automatically go into the bulk/junk/spam email folder. Hey, dummies who pay for spam email marketing are dumb, your marketing spam gets delivered but never gets opened. You advertisers are totally wasting your money!
