Get my free temp emailA temporary email address — also called disposable email, throwaway email, or burner email — is a real, fully working email inbox that you can use once and then discard. Unlike a permanent address such as gmail.com or outlook.com, a temporary address has a built-in expiry timer. When the timer runs out, the address stops receiving mail and every message ever delivered to it is permanently deleted from the server.
The key difference from your real inbox is that nothing links the temporary address to you personally. There is no name attached to it, no phone number, no date of birth — just a randomly generated string before the @ sign and a domain managed by the service. You never signed up with any personal details, which means the address cannot be traced back to you even if the service were breached.
Temporary email addresses look and function exactly like real email addresses. They have the same format (name@domain.com), they receive messages via the standard SMTP protocol, and the emails that arrive in them contain the same headers, attachments, and links as any other email. The only difference is the lifespan and the lack of a permanent identity attached to them.
The modern web runs on email gates. Nearly every website — from a news article to a PDF download to a SaaS free trial — requires an email address before it lets you in. The problem is that handing over your real address has a compounding cost over time.
The moment you enter your real email on a website, it enters that company's database. From there, several things can happen: the company sends you marketing emails you never asked for, the database is sold to third-party advertisers, or the company experiences a data breach and your address ends up in a list sold on the dark web. Each of these outcomes happens far more often than most people realise.
According to breach-tracking services, over 10 billion email records have been exposed in publicly known data breaches. If you have had the same email address for more than five years, there is a high probability it appears in at least one of those lists. The consequences range from annoying — your inbox fills with spam — to genuinely harmful, as attackers use known email addresses to target phishing campaigns.
Temporary email solves this by giving you a working inbox for the duration you need — typically the 30 seconds it takes to receive a verification code — and then making the address and all its messages vanish completely. There is no trail to follow, no address to sell, and no inbox to spam.
A service like My Temp Mail operates a real mail server with real DNS MX records pointing to it for several owned domains. When you click Generate, the service creates a new entry in its database associating a randomly generated local part (the bit before the @) with one of those domains. From that moment, the mail server is configured to accept incoming SMTP connections delivering to that address.
Any website can send email to your temporary address. The email travels through the internet via standard SMTP — exactly as it would travel to a Gmail or Outlook address. When it arrives at My Temp Mail's server, it is stored in a short-lived database record tied to your inbox session.
Your browser receives the email in real time using Server-Sent Events (SSE), a technology that maintains a persistent connection between your browser and the server so that new messages appear in your inbox within seconds of arriving — without you needing to refresh the page.
When the address expires, a scheduled cleanup job runs. It removes the address from the mail server's accepted-recipients list (so future emails bounce rather than being delivered to nobody), deletes every message from the database, and removes all associated metadata. Nothing is archived. Nothing is moved to cold storage. The data is gone.
The range of people who use disposable email every day is broader than most people expect:
Estimates suggest hundreds of millions of temporary email addresses are generated every month globally. It is no longer a niche privacy practice — it is becoming standard behaviour for anyone who pays attention to what happens to their data.
Yes. Using a disposable email address is completely legal in virtually every country. It is simply a privacy tool — legally and conceptually no different from using a PO box instead of your home address for physical mail, or using a pseudonym when posting publicly online.
The temporary email service itself is legal because it operates a genuine mail server and delivers real email. There is nothing deceptive about the technology. The emails that websites send to temporary addresses are delivered and received — the service is not intercepting, forging, or blocking email.
Some websites prohibit the use of disposable email addresses in their terms of service. Violating a website's terms of service is a civil matter between you and that website — it is not illegal. In practice, enforcement is impossible: a website can reject known disposable domains, but it cannot compel you to use a permanent address.
Temporary email works well in any situation where the interaction is genuinely one-time and you do not need long-term access to the account. Common and legitimate uses include:
Temporary email is the wrong tool for situations where you need long-term, reliable access to an account. The most important cases to avoid:
The simple rule: if you will ever need to access the account again or rely on it for anything important, use your real email address. If you are genuinely just getting something once and walking away, a temporary address is the smarter choice.
My Temp Mail operates across multiple owned domains, which matters because many websites maintain blocklists of known disposable email providers. When one domain is added to a blocklist, you can switch to another from the dropdown — the address changes but the inbox behaviour remains identical. The service also delivers email in real time via SSE rather than requiring manual page refreshes, making it fast enough for time-sensitive OTP codes.
Unlike some disposable services, My Temp Mail deletes all data permanently when an address expires. There is no server-side history, no admin panel with a copy of old inboxes, and no backup that could be subpoenaed or breached to reveal past messages. What is gone is genuinely gone.
