To create a temporary email with TempMaily, you do not actually create anything — you just open the site. A random disposable address is generated and live before the page finishes loading, with no signup, no password, and nothing to confirm. Copy it, paste it into whatever form is asking for an email, and read the incoming mail in your browser in real time. That is the entire process.
Most guides on this topic describe a multi-step ritual because older services made you jump through hoops. Modern disposable email is close to zero-step. This tutorial walks through it end to end anyway — getting the address, using it, receiving a code, switching to a fresh one — and then compares the different ways people get a throwaway inbox so you can pick the right one.
Quick answer
Open TempMaily, copy the generated address, paste it into the signup or verification form, then read the incoming message in the inbox on the page. No account, phone number, password, or setup is required for the free tier. The address is meant for short-term use and expires after 24 hours, so switch to a real inbox or a durable Premium address for anything you need to keep.
If you need another address, use Change email to generate a fresh inbox.
Step by step: get and use a temporary email
Here is the whole flow, start to finish.
1. Open TempMaily to get an instant address
Go to TempMaily. Before you can even click anything, a random address on a shared domain is waiting for you — something in the form [email protected]. There is no account to make. The inbox is already yours for the session.
2. Copy the address
Click the copy button next to the address. That puts it on your clipboard so you can paste it into a signup form, a checkout field, or wherever a service is demanding an email before it will let you continue.
3. Use it wherever you need an email
Paste the address into the form and submit. From the service's point of view this is a completely normal, working email address — because it is. Mail sent to it will be genuinely delivered; it is simply not tied to your real identity.
4. Receive the verification code in real time
Switch back to your TempMaily tab. When the service sends its confirmation email or verification code, it appears in your inbox the moment it arrives — no refreshing, no waiting, no manual checking. Open the message, read the code or click the link, and you are through. Messages are sanitized and shown in a sandboxed viewer with remote images blocked, so tracking pixels cannot fire when you open them.
5. Change your address when you want a fresh one
Done with that inbox, or need a clean one for a different signup? Use Change email to instantly abandon the current address and generate a new random one. The old inbox is gone; the new one is ready immediately.
6. Know when to switch back to your real inbox
This is the step most guides skip. A temporary email is perfect for one-off signups, but you should switch to your real address the moment an account matters — anything you will log back into, anything tied to payment, anything where you might need a password reset next month. More on that below.
The different ways to get a temporary email
"Temporary email" can mean a few different things depending on the tool. Here is how the common approaches actually compare.
| Method | Setup effort | Anonymous? | Real-time inbox | Best for |
|---|---|---|---|---|
| Dedicated service (TempMaily) | None — instant | Yes | Yes | One-off signups, testing, spam avoidance |
| Gmail "plus" alias ([email protected]) | None if you have Gmail | No — same inbox | Yes | Filtering mail you still want |
| Browser extension | Install required | Varies | Sometimes | People who want it built into signup forms |
Dedicated disposable service
A service like TempMaily gives you a genuinely separate, anonymous inbox with nothing linking it back to you. It is the right choice when you want the address — and everything sent to it — to simply disappear. Because it is receive-only and transient, there is nothing to leak later.
Gmail plus-addressing
Adding +something to your Gmail address ([email protected]) is a neat trick for tagging and filtering mail, but it is not disposable and not anonymous. Every message still lands in your real inbox, and anyone can strip the tag to find your true address. We break this down fully in temp mail vs Gmail plus-addressing — it is a filtering tool, not a privacy tool.
Browser extensions
Some extensions inject a throwaway address directly into signup forms. Convenient, but you are trusting the extension with everything you type. A hosted service you open in a tab keeps the boundary clearer.
A real scenario: the 10%-off code
Say you are checking out at an online store and a banner offers 10% off for signing up to the newsletter. You want the discount, not a year of marketing email. Open TempMaily in a second tab, copy the address, paste it into the newsletter box, and grab the code from the message that lands seconds later. Apply it, finish your order, and close the tab. The store's future emails pile up in an inbox you have already forgotten. For more on this exact use case, see temp mail for online shopping and temp mail for signups and free trials.
Common mistakes to avoid
- Using a free temp inbox for an account you care about. Free addresses expire in 24 hours. If you register your primary bank, email, or work account against one, you will lose the recovery path. Read how long a temporary email lasts before you rely on one.
- Expecting to reply. Free TempMaily inboxes are receive-only. If you need two-way mail, Premium auto-forwarding relays incoming messages to your real inbox instead.
- Assuming it hides you from everyone. A throwaway address protects your primary inbox from spam and breaches, but it is not anonymity from law enforcement or a way to break the law. See is temporary email safe for an honest picture of what it does and does not do.
- Forgetting you switched addresses. If you hit Change email before reading a code, the old inbox is gone. Grab the code first, then switch.
Free versus Premium at a glance
The free flow above covers almost everyone. If you need throwaway addresses regularly or for work, Premium adds custom and dedicated domains, unlimited concurrent addresses, no-expiry or customizable expiry with restore, auto-forwarding to your real inbox, 2GB of storage, a REST API with webhooks, and QR codes for your addresses.
