Show HN: Zuhal – A Fast and Accurate Email Validation Service

https://zuhal.io
1•shirazshaikh•4h ago
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 site: [https://zuhal.io](https://zuhal.io)

Happy to answer any questions!
