Hey HN, I'm Chris, CTO of Knock (https://knock.app). We built email.info because every developer we talk to asks the same question: which email provider should I use? The existing resources are mostly vibes — "Best of" listicles, anonymous Reddit threads, or LLM answers trained on that same content. Objective performance data is always missing.

Since Arc was acquired by Atlassian, I’ve been wondering: what if I built a new interface that applied Arc’s UX to email rather than browser tabs, while making AI agents easily available to help manage emails, events, and files?
