Creating a temporary email address takes about five seconds. You do not fill out a form, choose a password, or verify anything. You open the page and your inbox is already there.

This guide walks through exactly what happens on Temp Email, what you can do with the address, and when to use a real inbox instead.

How to create a temp email on Temp Email

Open tempinbox.dev in any browser. Your address is generated automatically — it appears at the top of the page the moment it loads.
Copy the address. Click the address or the copy button next to it. It is in the format [email protected].
Paste it into whatever form you are filling. Signup pages, download gates, newsletter forms, trial registrations — anywhere that asks for an email.
Wait for the email. Stay on tempinbox.dev. Incoming messages appear automatically. Most verification emails arrive within 30 seconds.
Copy the code or click the link. Open the email, get what you need — verification code, magic link, download URL — and complete the task.
Done. The inbox stays in your browser until you delete it. Come back anytime in the same browser to check for follow-up emails.

What "no signup" actually means

Most email services require you to create an account before you can receive mail. That means choosing a username, setting a password, sometimes verifying a phone number, and agreeing to terms. Then you have yet another account to manage, forget about, and eventually find in a breach notification.

Temp Email skips all of that. The address is generated the moment the page loads. Access to the inbox is stored in your browser's localStorage — a small piece of data your browser keeps locally. No server account is created. No password is needed.

How many temp emails can you create?

Temp Email supports up to 3 simultaneous inboxes in the same browser. Each one is independent — separate address, separate inbox, separate purpose. A useful default setup:

Inbox 1: product trials and free-tier signups.
Inbox 2: content downloads and newsletter previews.
Inbox 3: testing, QA work, or anything miscellaneous.

To create a second or third inbox, use the inbox switcher in the top navigation. To delete an inbox you no longer need, use the delete option in the settings panel.

How long does the temp email last?

Unlike services that expire addresses after 10 minutes, Temp Email inboxes persist in your browser until you explicitly delete them or clear your browser's site data. There is no countdown timer.

Practical consequence: if a verification email takes 20 minutes to arrive, it will still be there. If you start a trial and the service sends a follow-up email the next day, the inbox will still be waiting. You can close the browser tab and come back later — the address and all received messages are preserved.

What temp email is used for

Account verification: signup confirmation codes and magic login links.
Product trials: evaluating software without committing your real inbox to months of marketing.
Gated content: whitepapers, reports, templates, and tools that require an email to access.
Newsletter previews: checking what a newsletter looks like before deciding whether to subscribe with your real address.
QA testing: developers testing signup and verification flows without polluting real inboxes.
Low-trust signups: any website you do not fully trust with your primary email address.

When not to use a temp email

Use your real email address for any account where you might need recovery access later: banking, healthcare, payroll, legal documents, primary social media profiles, or anything tied to payments. A temporary inbox that lives in one browser is not the right anchor for an account that matters.

The decision rule: if losing this inbox in six months would be a problem, use your real address.

Does it work on mobile?

Yes. Temp Email works in any mobile browser. The inbox persists in mobile localStorage the same way it does on desktop. If you use the same browser app on your phone consistently, the inboxes will be there each time you open tempinbox.dev.

Frequently asked questions

Is creating a temp email free?

Yes, completely free. No paid tier is required to create or use temporary inboxes on Temp Email.

Do I need to remember the address?

No. As long as you use the same browser and have not cleared site data, tempinbox.dev will reload your inboxes automatically. You never need to remember or write down the address.

Can I choose a custom address name?

Yes. The address name field on the inbox creation screen accepts custom names if you want a specific prefix instead of the auto-generated one.

What if the site blocks temporary email domains?

Some platforms actively block known disposable email domains. If this happens, you may need to use a different approach — an email alias service, or a secondary real address you reserve for low-trust signups.
