Long-term ESP performance in spamtraps

A collaborator inspired me to draw a few more graphs (you know who you are, and thank you very much for the idea).

I had retained the numbers for the ESP blogs ever since May, so it occurred to me that it might be pertinent to do a time series. The graphs are expressed in percentages against the total amount of ESP spam received, so the growth of total volume (for example, as a result of adding more spamtraps) is already accounted for. Since the data points are naturally mostly at the low end of the scale, a logarithmic scale seemed appropriate.

So, please find enclosed three graphs of ESPs appearing in spamtraps, divided into Transactional, SMB Marketing and Enterprise Marketing. The selection of ESPs and their division to these three categories is according to the ideas of the collaborator. NB. We only started tracing Zeta Interactive in August.

This post marks the second anniversary of this series (which was not intended to become a series or any sort of regular occurrence in the first place). I’d like to take this opportunity to thank everybody who is paying attention and sharing these posts in social media, and I’m very much looking forward to meeting a significant part of you all in two weeks – that is, assuming that Finns with ESTA are still allowed in. 😀
