September 6, 2026 I finally launched MailOnce after months of building

After months of building, testing and fixing things, I finally launched MailOnce.

It's a free temporary email service with private inboxes, real-time email delivery, OTP detection and verification link detection.

The funny part is that after launching, I realized building the product was the comfortable part. Getting real people to discover it and tell me what works or doesn't is much harder.

So for now I'm trying to resist adding more features and focus on talking to users instead.

If you want to try it: https://mailonce.org

Feedback is very welcome, especially the critical kind.

I built MailOnce because I wanted a temporary email service that felt fast, private and actually reliable, I want to make temporary email faster, more private and easier to use, especially for verification OTPs and links
