March 2016 in Spamtraps: ESPs and Social Networks
Coming in a little late this month. The percentage of ESP sent mail vs all mail seen in the spamtraps is only 0.6% this month; it has to do both with seeing less ESP mail (about 80% of last month’s figures), and a huge increase in botnet spam. Technically, this is a top 11 list this month because Topica and Oracle Marketing Cloud managed to match spam counts so closely that a comparison would be meaningless.
