False positives still a problem

This press release gives you access to a Lyris report on how different ISPs and webmail services are doing in terms of delivering legitimate permission-based bulk email.
On the whole, things look reasonable, but that masks a few problems you need to know about.
In Q2 2006, 87% of sent mail got through to the recipient's inbox at US ISPs and email providers. Of course, a 13% failure rate is a lot of money left on the table, but not catastrophic. And delivery rates improved compared with the same period last year.
Delivery rates for Europe fell slightly compared to Q2 2005, but 91% still reached inboxes.
Those that don't reach inboxes either hit the junk folder or get filtered out as spam (false positives). On the whole, false positives aren't a huge problem. Lyris say 3.3% of the permission emails were filtered as spam in the US, just 0.075% in Europe.
But these relatively favorable figures mask big differences between ISPs.
If hotmail.com addresses dominate your email list, you may have a problem: the false positive rate is a mammoth 18.2% for that service.
All the more reason to track your delivery statistics by domain, rather than just looking at the overall figure.
