inbox-placement

What problem does it solve?

This Skill eliminates guesswork when emails land in spam folders, Gmail Promotions tabs, or Outlook Other inboxes despite proper SPF/DKIM/DMARC authentication setup, or when launching new sending domains and needing to maximize initial inbox placement. It breaks down the exact signal hierarchy (sender reputation, engagement, authentication, content, infrastructure) that major mailbox providers use to classify incoming email, so you can target fixes to the highest-impact areas instead of wasting time on low-impact content tweaks.

Core Features & Use Cases

• Signal Hierarchy Breakdown: Clear 2025 weighting of key placement signals across Gmail, Microsoft, and Yahoo, so you know what to prioritize first for maximum impact.
• Provider-Specific Placement Guides: Step-by-step guidance for optimizing Gmail Primary vs Promotions tab placement, Microsoft Focused vs Other vs Junk filtering, and meeting 2025 bulk sender requirements for each provider.
• Diagnostic & Monitoring Frameworks: Actionable troubleshooting steps for spam placement, tab misclassification, high bounce rates, spam trap risks, and engagement decay, plus guidance on setting up inbox placement testing and monitoring key metrics long-term.
• Use Case: If your marketing emails are landing in Gmail Promotions despite strong engagement, use this Skill to adjust your sending practices, content, and engagement strategy to either move toward Primary tab placement or optimize your Promotions tab performance for better open rates.
