Things have been insanely busy the last few days so blogging has been light. I do have links to a few news articles though. ClickZ has a report on the benefits they saw when switching to a professional email service provider. ReturnPath talks about changes to the email landscape as we enter the holiday shopping season. Terry Zink talks about how he measures the effectiveness of filters. A commenter on this blog asked about how to improve delivery to AOL, and I should have an answer to that in a few days.
