A SaaS tool that scans email HTML for dark mode vulnerabilities, automatically generates optimized code with proper media queries and meta tags, processes images for dual-mode compatibility, and provides live previews across 20+ email clients. Users can deploy fixes directly to their ESP via native integration or export clean code, eliminating technical complexity.

Dark mode usage exceeds 80% on mobile email clients, which now aggressively auto-invert colors without designer control. Email marketing volume continues to rise, but ESPs provide minimal native dark mode support, creating a critical gap as brands face increasing pressure for pixel-perfect consistency.
