About Thirtel
Thirtel exists because disposable email shouldn’t feel like junk as a product. Most temp-mail sites work until you notice the popunders, the vague “we delete stuff eventually” story, or a send button that mostly fails.
I’m Aarish Rathi. I built Thirtel: receive-only temporary inboxes that actually expire, a couple of browser-side helpers for passwords and signup test data, and guides that say what the tool can and can’t do. Tagline: Temporary, on purpose.
Why it exists
The job is simple — catch one verification message without stuffing your real inbox. The category made that job feel sketchy. Cluttered UI. Unclear retention. Features that sound good until you realize outbound mail from a shared disposable domain rarely lands where you expect.
So the brief stayed narrow. Make “temporary” true. Keep the UI calm. Write the limits in plain language. Receive-only in v1. Thirty minutes by default. When the timer ends, the mailbox is gone. Those aren’t placeholders for a later “pro” story that quietly walks them back.
What we care about
- Temporary means temporary. No soft claims about retention or send.
- Short sentences. No fear copy, no hype.
- Free shouldn’t feel cheap. The task comes first.
- Signups ask for more than an email, so password and test-identity tools sit next to the inbox.
How it works
You get a short-lived address. Mail sits in temporary storage on a timer. When the timer ends, the inbox is gone. v1 doesn’t send from that address. The password and fake-identity tools run in your browser — those strings never hit Thirtel’s servers.
Under the hood it’s Cloudflare edge infrastructure. Mail comes in, gets parsed, gets written with the same expiry you see in the UI. Your browser polls while the inbox is live. There’s no long-lived database of old inboxes to dig through later.

Who it’s for
People who want a verification without handing over their permanent address to something low-trust. Developers who need an OTP in staging without a full mail stack. QA folks who need synthetic form fields for a walkthrough.
Not for banking, government portals, healthcare, employer SSO, or anything you might need to recover in six months. Those need a durable address. We say that on the homepage, in the guides, and in the Terms because the wrong tool there actually hurts people.
The guides
Temp mail is full of myths — “temp Gmail,” send buttons that don’t deliver, five-minute clocks that die before the code arrives. The guides are there for that. Definitions, duration, safety, when not to use it. Useful even if you never open a Thirtel inbox.
What we won’t do
- Issue fake @gmail.com or @outlook.com addresses.
- Promise anonymity email can’t deliver.
- Pretend outbound mail from a shared disposable domain is reliable.
- Help with fraud, phishing, impersonation, or skipping real identity checks.
- Keep expired inboxes “just in case.”

A note from me
I kept needing a clean temporary inbox and kept landing on sites that treated me like ad inventory. So I built a small one: receive-only, real timer, two local helpers for the rest of a signup form, and writing that doesn’t oversell the category.
If something’s unclear, broken, or dishonest in how we describe the service, email me. Temporary contact should feel intentional — useful for a few minutes, gone when it should be, honest about the limits.
