ISPs May Be Blocking More Mail Than They Realize
An interesting article in ISP-Planet on deliverability discusses a study conducted by Lyris (.pdf) regarding the deliverability of legitimate email during 1Q2005, in both US and European ISPs. Unfortunately, the study covers unconfirmed opt-in mail of various types, calls SpamCop an ISP, does not discuss the actual reasons for the mail being blocked or filtered into spam mailboxes, etc. So in the end, the study is a meaningless jumble of statistics that the bulk mailers can trumpet to whoever will listen: "Concentric drops 61% of all legitimate email marketing!" "Yahoo can't tell the difference in 8.8% of cases between spam and our important news updates that could save you money!" "Gmail drops a fifth of all inbound mail!" And that, sadly, doesn't help anybody.
