I manage email campaigns for many different clients, and just this week I have started to notice a pattern - dozens of individual email recipients are each opening my email campaigns hundreds of times. I know that forwards can cause artificially inflated open numbers, but I'm seeing 100-200 logged opens. More interestingly, they seem to be clustered within certain email domains - in a campaign I reviewed today, the top 5 openers each opened the email between 150 and 200 times, and all 5 work for the same company and have the same email domain. The 6th and 7th most prolific openers have 150-160 opens each, and they both work for the same company. The 8-10 highest openers have 80-90 opens each, and they too all work for the same company. Does anybody have any insight into what might be causing this, and how I can weed these artificially inflated numbers out?
