spam-filter-avoidance

What problem does it solve?

This Skill solves the issue of legitimate emails being routed to spam folders due to content-level triggers, even when your domain authentication and sender reputation are properly configured. Many senders waste time optimizing their sending infrastructure while overlooking simple content mistakes that push their emails into spam.

Core Features & Use Cases

• Spam Trigger Identification: Highlights high-risk subject line phrases, body content patterns, and hidden text tricks that trigger both ML-based (Gmail, Outlook) and rule-based (SpamAssassin) spam filters.
• Link & HTML Best Practices: Guides you on safe link usage (no URL shorteners, descriptive anchor text, HTTPS) and well-structured HTML that avoids flags like excessive link density or image-only content.
• Provider-Specific Compliance: Covers unique filtering requirements for Gmail, Microsoft Outlook, Yahoo, and enterprise spam filters, plus mandatory headers like List-Unsubscribe for bulk senders.
• Use Case: For example, if your monthly marketing newsletter is consistently landing in Gmail's spam folder despite good domain reputation, use this Skill to audit your content and fix filter triggers before your next send.
