ESP mail seen in spamtraps, March 2017

The percentage of ESP sent mail vs all mail seen in the spamtraps is 3.0%, which continues to be quite large. The amount of ESP mail is up 15% from last month, of all mail, 29%.

The Nordic (Finnish, Swedish, Danish, Norwegian) porn/dating spammers have found ConsultorPC this month, so they’re making an appearance at #4. This ESP essentially does not exist for the purpose of this blog – except when it has an infestation, like it last did in July 2016.

AWeber continues providing services to what looks like the same make-money-fast schemes as previous months – you would think they would have gained religion by now.

Other than that, the top ten is made up of the usual suspects.

Bubbling under this month: Mapp Digital (2.5%), only ever so slightly behind IBM Marketing Cloud.

0 All others 40.0%
1 SalesForce Marketing Cloud 10.6% ExactTarget Kohls (2.5%)
2 SendGrid 10.3% (4.9%)
3 MailChimp 7.2% (6.1% Mandrill) Limbino (.com,, .se, .nu) (2.6%)
4 ConsultorPC 6.8%,, (>97%)
5 Experian 6.5% Target (8%)
6 Constant Contact 4.4% Advisor Perspectives (47%)
7 Amazon SES 3.5% (6.4%)
8 Oracle Marketing Cloud 3.2% Responsys, Eloqua and RightNow Nordstrom (11%)
9 AWeber 2.6% Various make-money-fast spammers (top 5 amounting to slightly less than 40%)
10 IBM Marketing Cloud 2.5% The DCCC (9%)

Here’s the “relative badness” graph, with ConsultorPC’s single bad actor taking them to the top even over Digital Metrics.

Zeta Interactive should take a look at Dick’s Sporting Goods, Inc.

MailMinion are still sending. With a total Spamhaus listing for MailMinion having been there for soon three quarters, it’s quite amazing that they still bother.

French ESP Edatis are spewing… à ouest, rien de nouveau.

Sailthru’s consistent high position on this chart is due to a relatively small number of customers who are banging the living daylights out of email addresses that never existed.
