I was monitoring sends across all of our clients on Tuesday and noticed in the bounce reports that AOL was having some issues with certain blocks. As I investigated it further, I found that they were 554 RTR:GE blocks which according to the AOL Postmaster site are “a transient error indicating a technical issue on AOL’s side. Please wait 24 hours and re-try your mail”
Laura Atkins over at Word To Wise confirmed this report today here. According to her, these blocks have nothing to do with spam, filtering or any other type of malicious email and they apparently work them out over time.
So if you track revenue, pageviews or even engagement by domain and notice that AOL took a dip, now you know why.
