Summary
Yahoo and Microsoft provide various tools to assist senders in monitoring email deliverability, akin to Google Postmaster Tools. Microsoft's primary tool is SNDS (Sender Network Data Services), which focuses on IP reputation and provides insights into complaint rates. They also utilize JMRP (Junk Mail Reporting Program) based on user reports. Yahoo provides resources via bulk sender guidelines, a Feedback Loop (FBL) to address spam complaints, and postmaster information. Verizon Media's postmaster page is also relevant. Yahoo leans towards domain-based authentication (d=domains), while Microsoft's approach is more IP-centric. Sender reputation is crucial for both. SNDS might not be as useful for shared IP addresses. Correct reverse DNS records are vital for building trust. Some Yahoo services may be paid or in beta. Microsoft also has a Certified Senders Program and emphasizes adhering to sending limits.
Key findings
- Microsoft SNDS: Monitors IP reputation, providing data on complaints and authentication issues. Key for Microsoft deliverability.
- Yahoo FBL: Identifies and helps remove users marking emails as spam, improving sender reputation.
- Verizon Media Integration: Verizon Media Postmaster offers insights for senders as Yahoo is under Verizon.
- Reputation Emphasis: Both Yahoo and Microsoft prioritize sender reputation when evaluating deliverability.
- Microsoft JMRP: Uses data from user-reported spam to improve its spam filtering.
Key considerations
- Shared IP Limitations: SNDS primarily focuses on IP reputation, posing limitations for shared IP users. SNDS doesn't function effectively with shared IPs.
- Reverse DNS Importance: Correctly configured reverse DNS (rDNS) is crucial for establishing trust.
- Tool Costs and Availability: Be aware that certain Yahoo services might involve costs or be in beta, limiting accessibility.
- Sending Limits: Adhere to Microsoft's email sending limits to maintain sender reputation and avoid deliverability problems.
- Authentication Differences: Recognize that Yahoo prefers domain-based authentication (d=domains), whereas Microsoft is largely IP-based.
