What Offex Mail is
Offex Mail is a free temporary email service. In one click it gives you a working disposable inbox that you can use anywhere a website asks for an email address. There is no account to create, no password to remember and nothing to pay — you open the page, an address appears, and mail sent to it lands there within seconds.
The inboxes are not borrowed from someone else’s domain. They run on our own domain, mytemp-mail.online, which means the addresses are real and deliverable. When a service asks you to confirm your email, the verification message actually arrives.
Why we built it
Most of us give away our real email address far too often. A one-off download, a trial, a coupon, a forum signup — each one asks for an address, and each one becomes another source of newsletters, marketing mail and eventually spam. Over time that clutter buries the messages you actually care about.
Offex Mail exists to break that habit. Instead of handing over your personal inbox for something you only need once, you use a throwaway address that does the job and then disappears. Your real inbox stays clean, and the service that needed verification still gets what it asked for.
We also wanted the experience to be genuinely simple. Many disposable email sites bury the inbox behind pop-ups, countdowns or forced sign-ups. Offex Mail does the opposite: the address is ready the moment the page loads, mail appears live, and there is nothing to install or configure. If you only need an address for a single signup, you should not have to work for it.
How it works
Create an address
Generate a random address instantly, or type a custom name you prefer.
Use it anywhere
Paste it into any signup form just like your normal email address.
Receive mail
Messages appear in seconds, with a chime so you never miss one.
Let it expire
The inbox clears itself automatically — no cleanup required.
OTP auto-detection
Many signups now send a one-time password or a verification code instead of a link. Hunting for that code inside a long email is fiddly, especially on a phone. Offex Mail scans incoming messages and surfaces the code for you, so you can copy it and paste it into the form without reading the whole email. It is a small feature, but it is the one people notice most.
Free, and on our own domain
Offex Mail costs nothing and asks for nothing in return. There is no premium tier hiding the useful parts, and no requirement to link a phone number or a social account. Because the inboxes live on our own domain rather than a shared one, verification emails are far less likely to be silently blocked or marked undeliverable, so the message you are waiting for actually turns up.
Who it is for
- Anyone signing up for something once. Trials, downloads, coupons and one-off forms no longer need your real address.
- Privacy-conscious users. Keep your personal inbox out of mailing lists you never asked to join.
- Testers and developers. Check that signup flows, confirmation emails and OTP screens work as expected.
- Students and researchers. Register for resources and tools without accumulating years of marketing mail.
What Offex Mail is not
A disposable inbox is a shield, not a vault. Because anyone who knows a temporary address can read its messages while it is active, Offex Mail must never be used for banking, medical, government or other confidential accounts. Use it for throwaway signups — and keep a proper, secure mailbox for anything that genuinely matters.
