April 2017 in Spamtraps: ESPs

ESP mail seen in spamtraps, April 2017

ESP mail seen in spamtraps, April 2017

The percentage of ESP sent mail vs all mail seen in the spamtraps is 1.6%, only almost half of last month. The amount of ESP mail is down 33% from last month; the amount of all mail is up nearly 30%.

The Nordic (Finnish, Swedish, Danish, Norwegian) porn/dating spammers went to the Danish ESP MySMTP this month, so they made #5 and will in all likelihood be making #3 next month unless MailChimp develops a big problem later. (After MySMTP termed them in early May, they went back to Dyn, were quickly termed manually, and attempted to sign up with SendGrid, where they were terminated by automatic scripts before I had even sent in a complaint.)

AWeber is still asleep at the wheel.

Bubbling under this month: Digital Metrics, Mapp Digital and Epsilon, all hovering around 1.8%.

Final note: MailMinion has essentially become a snowshoe spammer, with 924 separate domain names each having mailed out just one message this month out of the 1066 that sent anything.
