ZUHAL

Hi HN, I’ve been working on Zuhal, an email validation service designed for developers and marketers who need to ensure their emails reach real inboxes. Zuhal checks for syntax, domain validity, MX records, disposable addresses, and deliverability risks — all via a simple REST API or bulk upload. I built this because I faced deliverability issues with email campaigns and wanted a tool that’s fast, accurate, and affordable. I'd love to hear your thoughts, feedback, or suggestions for improvements. Also curious about how you handle email list hygiene in your projects or companies. Here’s the…

    Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you. What it checks: - Syntax – Confirms correct proper email format. - Domain & DNS – Verifies the domain exists and resolves. - MX records – Verifies the domain can receive mail. - SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent). - Disposable domains – Flags temporary inbox providers that can hurt deliverability lists. - Common typos – Catches mistakes and suggests fixes. How it works: Paste an email > click Validate > get a clear result with…

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
