Fine ladies and gentlemen of the email world, Is anyone noticing MS being particularly temperamental lately? I think it's a known fact that MS is not fond new IPs. At least from my experience, a new dedicated IP takes weeks to go 'green' and initial open rates can be quite sad, however, what I'm noticing within the past week is actual "Blocked due to user complaints or other evidence of spamming", even in scenarios, where a reputable sender is ramping up volume from a couple of hundred to a little over 1k contacts that have engaged within the past month. I submitted a support ticket, which resulted in 'not eligible for mitigation' response. Every other domain is performing well, which tells me that it's a solid list, but MS is like "nope, I want none of this". I'm kind of hesitant to submit an escalation request because last time we tried, it resulted in reputation being reset for all IPs in that range, causing serious deferrals that affected dozens of clients with dedicated IPs in that range. I might have to go that route again, but very uneasy about it. Does anyone have a similar experience or any advice, when it comes to new IPs and MS domains? I generally like to keep initial sends via a new IP to 2,500 across all domains and double the volume every 1-2 sends after. Is this too much? Again, in the past, the initially low IP reputation just caused emails going to spam, but the actual IP blocks we're seeing now are worrisome. Thanks in advance!
Allen K
