Email blocking and filtering report
Return Path released this 2 page .pdf report indicating that top ISPs are blocking or filtering out an average 17% of legitimate permission-based emails. In other words, it's confirmation that the war on spam is affecting more than a few innocent bystanders. In more bad news, non-delivery rates reached as high as 38% with some ISPs.
Interesting to note though that non-deliverability split by the sender's industry varied between 1% and 46%. So if I was a permission-based marketer, I'd be looking at those industries' practices to find out why.
