The digital signage company Four Winds Interactive is spamming several spamtraps via ESP ExactTarget. One spamtrap might be a mistake; several at different domains almost certainly means a purchased list.

  1. Hey SpamBouncer, I’m going to start keeping an eye out on this blog for stuff I should investigate. In this case, we’ve launched an investigation and already found that this client was digging too deep for email addresses — some sort of old list or subscriber database that nobody is really sure where it came from. So, we’ve made that go away, and the spamtrap hit(s) should cease. Feel free to post here or email me (abuse AT if you see a recurrent issue before I do.

    • Good to see an ESP representative here on the blog! And I’m glad to see that you looked into this issue. While our main purpose here is to educate companies, we hoped that ESPs would show up and use this information for the good. 🙂

      I’m not surprised that the client had some old lists that they reactivated; that’s exactly the sort of thing that would cause several hits on the sorts of spamtraps that were once legitimate email addresses. I’ll monitor mine and let you know if anything continues to show up.
