I got tired of 10-minute mail tools.
You sign up somewhere, wait for the verification code, and the inbox is already gone.
So I built TempMail.is, a free disposable temporary email service that stays until you delete it.
What it does
- Instant free temp email, no signup
- Persistent inbox, not locked to 10 minutes
- Custom aliases and multi-inbox
- Receive OTPs and confirmation emails in the browser
- Clean UI on desktop and mobile
Who it is for
- People who do not want spam in their real Gmail
- Quick signups, free trials, downloads
- Developers and QA testing registration and email flows
Try it
Feedback welcome
I would love thoughts on:
- UX (is anything confusing)
- Delivery reliability
- Features you would want next
If this is useful, a share helps a lot. Happy to answer questions in the comments.

I was particularly intrigued by the persistent inbox feature, as it addresses a common pain point with traditional 10-minute mail tools. The ability to receive OTPs and confirmation emails in the browser is also a nice touch, as it streamlines the signup process for users. From a developer's perspective, I can see how TempMail.is would be useful for testing registration and email flows, and I'm curious to know how you handled the technical challenge of maintaining a persistent inbox without requiring users to sign up. How do you plan to balance the trade-off between providing a free service and preventing abuse, such as spamming or using the service for malicious activities?
Thanks Luis — great questions.
Persistent inbox without signup: the address and mailbox stay available longer than classic 10-minute tools so delayed OTPs still land. No account is intentional — less friction for real use.
On free vs abuse: we use rate limits, abuse signals, and keep the product aimed at human OTP/signup use, not bulk sending. Happy to go deeper if useful — and feedback on deliverability is always welcome.
