I understand that their responses were very minimal and not helpful, but it clearly says in the requirements to make a "terminal-inspired" email client. However, in the video you shared [1] I see a somewhat generic email web app, with nothing particularly "terminal-inspired". Considering the fact that they wanted either a real TUI or a webapp, I'm pretty sure that the web app should've also been "terminal-inspired". Am I missing something? I'm not trying to necessarily criticize you, perhaps I just misunderstood the requirements.
Edit: I've actually checked the full requirements page, and they explicitly say this in "Inspiration":
> Your implementation should take inspiration from existing terminal email tools like aerc, mutt, or even something like himalaya.
