Show HN: Mailfrom.dev – A Cheaper MailTrap Alternative

I built Mailfrom.dev to fullfill a necessity I've had for years.. A simple, affordable sandbox SMTP server that lets you test email flows (resets, onboarding, verifications) in dev/staging environments — without sending real emails to real users and that can be shared with other people and clients.

Sure, there are other players in the space — but most are either way too expensive or require complex setups. I wanted something affordable and dead simple to use. Just check the pricing — you'll see what I mean.

Stack: Laravel, Vue 3, shadcn, hosted on k3s on Hetzner, using AWS S3 and SES.

Would love your thoughts or feedback — especially if you've struggled with email testing in staging like I have.

I’ve had folks ask about CI/CD integration and even snapshots of email contents (for visual diffs or regression testing). I’m now thinking ahead and would love your input:

If you were to use a tool like this, what features would you want most?

    Simulate bounces/spam?

    API access for email contents?

    CI assertions for email presence/structure?

    Anything weird or niche you've always wanted?
Appreciate any ideas or feedback — it helps shape the roadmap (Daniele, maker of Mailfrom.dev)
