Deliverability tested August 2026 – September 2026 · seed-list inbox placement
Click any column to sort. Services we have tested for deliverability always come first; untested services follow, sorted by the same column. User rating combines Trustpilot, G2 and Capterra, with Trustpilot counting for half; AI readiness scores MCP servers, agent skills, assistant apps, AI-friendly docs and built-in AI (70+ AI-native, 40+ AI-ready). Both are context only and never part of the Deliverability Score — how we use review platforms.
