Signup flow testing
Test signups for ten accounts on your own
The hardest part of testing signup isn't filling out the form—it's needing a new email address for every test run. Click “New address” to get a fresh inbox; the old address is invalidated immediately, keeping data from one test run separate from the next.
Ideal for QA regression testing, product reviews, and launch rehearsals. Complete the entire flow on one page: get an address → submit the form → receive a code → click the activation link—without using your personal email.

Receive verification codes
See codes at a glance and click activation links with ease
Can temporary email receive verification codes? Yes. The inbox checks for new messages every 7 seconds. Codes appear in large monospaced text, ready to copy without extra spaces. HTML emails render as intended, and you can click activation buttons and links directly.
Delete individual emails after reading. When you switch addresses or one expires, the entire inbox and its messages are deleted, so no one else can browse them.
Expiration
3 hours by default. Extend it anytime.
How long does a temporary email last? Each new address is valid for 3 hours by default, with a countdown beside it. Need more time to finish testing? Click “Extend.” If you extend first and then switch addresses, the new address inherits the remaining time—it doesn't reset the clock.
Need an address that stays the same for days or months? That's what a long-term forwarding alias is for.
Calculate how long to keep an addressYour test inbox shouldn't become another spam folder
Use your personal email for signup testing, and after a few rounds your inbox is full of welcome emails, promotions, and “You haven't finished signing up” reminders. A temporary test email keeps them in an address that disappears on its own. Finish testing and move on, without a trace.

Who it's for
What email should you use to test signups? It depends on what you're testing.
One inbox, three common use cases. Pick the one closest to what you're working on.
Marketing and product reviews
Before launch, check every welcome, activation, and password reset email for its layout, links, and sender name.
Trying apps and downloading resources
Want to try a tool or download a resource without being chased by marketing emails? Use a disposable email to keep them out of your inbox.
Email forwarding
Need an inbox for the long term? Use an email alias.
The difference between temporary email and an email alias comes down to lifespan and where messages go. Temporary addresses expire after a few hours, and you read messages on this page. Aliases stay active and forward messages to the regular email address you used to sign in. Pause or delete an alias whenever you like.
Sign in with an email verification code—no password needed. Add two-step verification for extra security, and view each alias's forwarding history from the last 30 days in your dashboard.
Can temporary email receive verification codes?
Yes. Verification codes for most website signups and logins, along with activation links, arrive in your inbox—usually within seconds. Some services block disposable email domains. If that happens, try a forwarding alias.
How long does temporary email last? What happens when it expires?
New addresses are valid for 3 hours by default. Click “Extend” before the countdown ends to keep using one. When it expires, the address and its messages are deleted, and the page automatically gives you a new address.
How can I test signups for multiple accounts on my own?
After each signup, click “New address” to get a fresh inbox. The old address is invalidated immediately. If you need to access an account later, use an alias so you can recover its password even after an address expires.
Can anyone else see my inbox?
Your inbox opens with an access token saved on your device. No one can see your messages without it. However, temporary addresses don't have passwords, so don't use them for important emails such as bank or identity document messages.
Can I send email with it?
No. Temporary test email is receive-only, and forwarding aliases only forward incoming messages to your regular email address.

Your address is waiting at the top of the page. Copy it and you're ready to go.
