I got sick of pop-under ads on temp email sites, so I built my own alternative.

Hey everyone,

Whenever I needed a disposable email to test a service or avoid spam, I noticed the existing tools were getting worse—slow load times, aggressive pop-unders, and layouts that constantly shifted.

So, I built TempMail (temp-mails.tech) to solve my own itch.

I focused heavily on the engineering and UX side:

- Nailed a 0 CLS (Cumulative Layout Shift) score so the UI is rock solid.

- Localized it natively into 12 languages.

- Implemented a strictly clean ad policy (standard banners only, absolutely no redirects or pop-ups).

- Added multi-domain support so users can switch if a specific domain gets blocked by a service.

It was a great challenge balancing a clean user experience with standard monetization. If you are launching products and need to test your email flows, feel free to use it.

I'd love to know what you guys think of the speed and the clean UI approach!
