I understood SmartScreen is a big black box for Microsoft, too and no one really knows why a message is blocked.. they simply trust the AI to work fine. They kept telling me it was about some content of my emails, but whatever email I sent from that IP, with whatever content, was classified as junk... while the same content from another IP was not junked.. so I don't call this "content filter". For sure the IP is also in the content if you take the MIME header as content. After opening a few tickets, each one with the same template-based answers telling us there was nothing offhand blocking our email at one point trying to insisting reaching an higher support tier they told me that my IP could be mitigated and that they mitigated the IPs and inbox placemnet improved a lot. I kept telling them that I don't want mitigation but I want to understand what is causing the issue in the first place otherwise I can't fix it, but they cannot share anything. So they mitigated but I don't know what's wrong and I'm just counting days to be junked again (FBL are low, open rates high.. and every other filter is happy... so I don't really know what to do for them). I opened 4 tickets in 6 months and get a few replies each time until they stopped replying. Last time they kept replying so I kept objecting their answer not being an answer to my question (they keep repeating to use SNDS/JMRP but my very first messaget was about SNDS/JMRP data that didn't give me any hint about something being wrong) and asking what "tier" I was talking to and to be elevated to an higher tier if possible. > We already monitor things like hard bounce rates, complaint rates, spam > filter analysis, spam trap hits, etc. for all of our customers and take > action on bad actors in our network.

I have suspects that if you follow best practices and stop writing to inactive users then gmail and yahoo are happy because your engagement rates improve, but microsoft is NOT happy at all because their "abuse / received" rate increase by decreasing the "ignored" email that don't generate abuses and they think your spamminess increased so they block you... just guessing.. but given we never had official answers in the past threads we can only share our guesses. I also guess there is a neighborhood issue because IP never used to send to microsoft junked or inboxed depending on the behaviour of the nearby IPs. So you have to take into consideration also nearby IPs. After the mitigation the headers of the emails are identical but now they end in inbox. BCL is still very high, but the email land in inbox, In my case when the IP was "junked" most email to recipients that received/opened in past where delivered to inbox, while email to new recipients ended in junk, so the effect of junking was more evident for new senders using the shared IP.
