Could you build this?
Partial The UI and static linting rules are straightforward, but accurate multi-client email rendering simulation across 20+ legacy clients like Outlook desktop requires a dedicated rendering farm.
What it would actually take: The architecture comprises a web platform and CLI linter backed by an orchestration cluster of headless virtual machines and emulators running native versions of Outlook (Word rendering engine), Windows/Mac native mail clients, and webmails. The hard part is reliably provisioning, automating, and maintaining these physical/virtual client instances at speed to generate instant screenshots and DOM diffs, or maintaining an exceptionally complex AST parser that accurately mimics proprietary rendering engines (like Microsoft Word's HTML/VML renderer).
