May 2017 in Spamtraps: ESPs
ESP mail seen in spamtraps, May 2017
The percentage of ESP sent mail vs all mail seen in the spamtraps is 2.4%, up 50% from last month, but it is mostly explained by the amount of all mail being down nearly 30% from last month.
The Nordic (Finnish, Swedish, Danish, Norwegian) porn/dating spammers went to the Danish ESP MySMTP in April and stayed until the beginning of May, so they made #3 this month as I predicted. They went to Dyn when MySMTP terminated them, causing over 70% of Dyn’s contribution this month. Dyn termed them quickly, at which point they went to SendGrid and got out maybe a handful of mails before SendGrid’s automatic scripts terminated them. They were also on Mailgun at the same time as on MySMTP.
Bubbling under this month: Dyn (3%), AWeber (2.5%), IBM Marketing Cloud (2.2%). AWeber is only down in the charts because everybody else is up; the same problems stay month after month.
