Complaints can only be generated when the mail is in the inbox. If mail is going to the bulk folder complaint rates will be low, even zero, because no one is given the opportunity to submit a complaint. As for the colors, two things. One: SmartScreen filters are a reflection of the content reputation not IP. Now, bad content can create bad IP reputation because ’this is an IP that sends bad content’ but content / domain rep are different things to IP rep and there are different things that create them. I don’t think good content can fix bad IP reputation, but it’s not an area I’ve ever explored so I could be very wrong there. Two: The colors do not reflect delivery. I have had dozens of clients over the years with red labels that reach the inbox. I’ve had dozens of clients over the years with green labels that are blocked or go 100% to spam. As to why this keeps happening, the underlying issue is simple to describe in the abstract. Recipients acted on mail coming from those IPs in a way that led Microsoft to believe that email was unimportant to their users. Initially, Microsoft put the mail in the bulk folder and waited for their users to complain. They also polled some of the recipients and asked them if the decision to put the mail in spam or the inbox was correct. None of Microsoft’s actual users said that MS was wrong. When the mail continued and the senders didn’t seem to care that the mail was going to bulk over a period of time then Microsoft escalated to rate limiting the sender. The sender still didn’t take action. Users still didn’t complain they weren’t receiving mail they wanted. Microsoft decided just to not waste the cycles delivering mail their users didn’t want, so they blocked the IP. You contacted them, they mitigated the reputation and reset it to basically neutral. Then, the cycle started again and they started monitoring how their users were treating the mail. Recipients acted in ways that led Microsoft to believe that the email was unimportant to their users. GOTO 1 Now, that’s not to say Microsoft doesn’t have some problems with filtering. They are one of the toughest delivery nuts to crack right now. The things we normally recommend to folks don’t always work as expected. Sometimes they do and we can fix things no problem. But sometimes they are just an inscrutable black box with variable responses. I have some theories as to why that is, but it’s all speculation at this point. I do think that spam to O365 is affecting reputation more than folks believe - and we have zero feedback from O365 domains either in the form of FBLs or SNDS. The other bit of speculation is that Microsoft as an entity just doesn’t really care what any outside company or person thinks. They do things The Microsoft Way. There isn’t the space inside the company for folks who know what the problems are to effectively advocate for change. I think there are lots of individuals who care and who see the issues, but the product developers / managers / owners just don’t care. They’d care if there were numbers to demonstrate the problem, but none of the numbers actually look like a problem. They also seem to have excessive problems with filtering recently - they blocked google and linkedin links in the last 2 days or so. Maybe getting in the press for screwing up their filtering will strengthen the voices of the folks internally to get the experts to give input on the product. Maybe it won’t. laura -- Having an Email Crisis? We can help! 800 823-9674 Laura Atkins Word to the Wise [email protected] (650) 437-0741 Email Delivery Blog: https://wordtothewise.com/blog
