Hi, I hope someone can shed some light on this. We've recently, per Return Path data, had some IP addresses start bulking at Hotmail. This has been off and on for the last 12 weeks or so - mostly on.
We've cleaned our list several times, inspected our email, kept the unknown user rates low yet this still seems to persist. I'm running out of things to do, check and change etc. Nothing seems to help. It's always the same IP addresses. The biggest problem, per RP data, seems to be message filtered. Our complaint rates both at RP and SNDS are low as are spam trap hits. The recipients these IP addresses send to are middle of the road, definitely not unengaged users but not the absolute most engaged that we have either. Yet neither of the other 2 sets (known as engaged and unengaged) of IP addresses exhibit this problem. My 2nd question surrounding all of this is how do I know what region is having the bulking? Including the U.S. we have 6 global regions where we market. Anyone have any ideas what I can check or what I'm missing? Thanks, John -- John Little [email protected] Mail Ops
