About TempInbox.online

We are developers fighting global email spam. That sentence is the entire mission statement, and everything about this service follows from it.

Why we built this

Every member of our team has watched a personal inbox slowly die. It starts innocently — you sign up for one webinar, download one whitepaper, buy one gadget from one online store. Then the drip begins: daily deals you never wanted, newsletters you never read, "we miss you" emails from services you used once in 2019. Multiply that by a decade of internet use, and the average inbox becomes an unusable pile of marketing noise where genuinely important messages go to die.

Worse, your email address is a tracking identifier. Data brokers buy and sell it. Breach after breach leaks it. Spammers scrape it. The modern internet treats your inbox as a resource to be extracted, and we think that is backwards.

What we believe

• Privacy is a default, not a premium feature. You should never have to pay to keep your personal email address private.
• Ephemerality is a feature. Data that doesn't exist can't be leaked, sold, or subpoenaed. Our mailboxes are designed to disappear.
• Tools should be boring and instant. No sign-ups, no onboarding flows, no dark patterns. Open the page, get an address, get on with your life.
• Free means free. The service is funded by non-intrusive advertising, and it always will be.

How the service works

TempInbox.online generates a random, fully functional email address the moment you load the page. Incoming messages appear in your browser in real time. When you're done — or when the mailbox expires — the address and every message it ever received are permanently deleted. Nothing is logged, nothing is archived, nothing follows you.

The service is receive-only by design. This is a deliberate anti-abuse decision: a disposable email tool that can't send mail can't be used to spam anyone. We're fighting spam, not enabling it.
