..or you are sending to a Microsoft-hosted email like @outlook.com, @hotmail.com or @live.com and they have decided that your sending server is spammy. In that case they will silently drop your mail.
- ryan-c 4y agoMy experience with this as been more that they will silently drop email if you haven't been sending enough legitimate email for them to classify you as non-spammy. How do you bootstrap that? I have no idea.
- account42 4y agoIME problems with Microsoft have been entirely with the using netblock-based blacklists that you can't do anything to prevent from ending up on unless you buy a whole /24. Thankfully, I don't really need to care about deliverability to MS so I can consider this their problem.
