Just got this email from AdKnowledge... Over the last several weeks some of you may have noticed that there have been negative impacts to AOL deliverability. These issues are an AOL internal issue and, as far as we know, may continue for the foreseeable future. Some of the issues are servers going down and tools they use to measure reputation being broken. Also, they have changed their reputation scale to only allow scores of 1-4 into inbox and everything above that will go to junk. We wanted to share these insights with you and will continue to share additional learnings.
