Email Blocking & Filtering Report, March 2005

ReturnPath released their 2004 year-end email deliverability report. In the report they found two big trends:

  • The false positive (non-spam ending up in the junk mailbox) is getting worse.
  • Companies that work on understanding, measuring, and solving the root causes of weak deliverability can raise their inbox rate dramatically in a short time.

ReturnPath also gives a nice chart that shows which of the top ISP rank in non-delivery issues. They found EarthLink with the lowest non-delivery rate and Road Runner with the highest.
