Building a simple, modern email hosting tool for custom domains, would you use it?

I keep running into the same wall: I want clean email addresses on my own domain (like [contact@mydomain.com](mailto:contact@mydomain.com)), but every option out there is either overkill (Google Workspace), limited (Zoho's free tier caps you at one domain), or just has a genuinely cluttered, dated UI that feels like it's from 2010.

So I'm building Kloff, dead simple custom domain email hosting. Add your domain, verify it with a couple DNS records, create mailboxes, done. No bloated dashboard, no per-seat enterprise pricing.

Nothing's built yet, I'm validating the idea first before sinking real time into it. If this is something you'd actually use, or if you've hit the same frustration, I'd genuinely love to hear it, and there's a waitlist if you want to get notified when it's ready: kloff.app

What do you currently use for this, and what annoys you about it?
