Good news for all of us who still have to use email: spam rates are dropping! In fact, junk messages now account for just 49.7 percent of all emails.
The latest figure comes from security firm Symantec's June 2015 Intelligence Report, which notes this is the first time in over a decade that the rate has fallen below 50 percent. The last time the company recorded a similar spam rate was back in September 2003, or almost 12 years ago.
More specifically, Symantec saw 704 billion email messages sent in June, of which 353 billion were classified as spam. At one of the peaks of the spam epidemic, in June 2009, 5.7 trillion of the 6.3 trillion messages sent were spam, according to past data from Symantec.

And you know this how?
My experiments suggest strongly that they do. That the same email when delivered from one IP address is marked as SPAM, but when delivered by a different address is not marked as SPAM is strong evidence that they do use some kind of IP reputation system. They might not call it an RBL, but it functions like one. Maybe it's not DNS based, hence the term RBL is not valid.
