Christmas is just about here and this year you can expect to see a flood of dodgy emails using fake invoices, and bills from energy providers and the like. This last year has been one of the worst ever for fake emails.
I have seen many people is small business spend 30 minutes each morning deleting spam and junk emails. This is a good way to ensure your junk emails continue to grow exponentially. Most junk and spam emailers use the same tools as email marketers to track what happens to emails when they are delivered.
They can tell who (which addressee) opened it and read it, who clicked on it to get to a link or deliver a virus or spyware, they can even tell where your mouse traveled on some emails.
The email that opens only in the reading pane will not register generally but it is a good idea not to delete the email as this tells the spammers what you did. If you right click the email and send it to junk they will not know what you did. Using this management method for spam it will reduce over time down to just about nothing. If you are not a live target they will quickly lose interest. It is tedious at first sending individual emails to the junk folder but the Microsoft junk email filters are state of the art and will work for you.
