How does Microsoft (Outlook, Hotmail) determine placement?
Microsoft (Outlook/Hotmail) uses SmartScreen and proprietary filtering:
IP reputation: Heavily weighted. New or low-reputation IPs face scrutiny.
Authentication: SPF, DKIM, DMARC evaluation.
Complaint rates: Feedback loop data influences filtering decisions.
Content filtering: SmartScreen analyzes message characteristics.
Sender certification: Programs like Return Path Certification (now Validity) can improve standing.
Microsoft tends to be more IP-focused than Gmail's engagement-centric approach. New senders often face warming challenges.
Microsoft's port values established trading relationships. New ships undergo thorough inspection.
