  Eight years ago, I was job hunting and felt embarrassed by my Gmail address. I tried registering firstname.lastname — taken everywhere. So I thought: "I'm in IT, I'll set up my own domain with my own IMAP/SMTP. How hard could it be?" A lot went wrong. Forgotten renewals. rocky DNS mistakes. I ended migrating toward Google Workspace, but in the end it felt overkill, having a subscription there plus the whole registrar subscription, and the whole GAFAM sticker on it.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
