Hi, I'm Debasish from India — an electrical engineer working at a power plant, not a professional software developer. I've been building side projects since 2015, starting with Railify, an Android app back when Java was the only option. Over the years I accumulated a lot of domains — each with its own mailboxes for sales, support, updates, and so on. Managing all of them across different UIs became genuinely painful. That frustration led me to build MailMark. MailMark lets you add your domains (abc.com, xyz.io, etc.), create mailboxes under them (sales@, founder@, marketing@), and manage everything from a single unified UI — think Gmail or Zoho, but for all your domains at once. On top of that:

Lightweight tracking: see delivery status, opens, bounces — all from one window Bulk campaigns: each recipient gets an individual mail, not a CC blast — similar to how GMass works Developer API: send emails programmatically with an API key, similar to Resend

There's a lot more in the product. Happy to answer any questions here. Check it out: https://www.mailmark.dev
