Now to 3 hours
Open the inbox to get an address, then sign up, receive your code, and activate your account. Check how much time is left regularly. Don’t assume verification is complete just because the sender says the email was sent.

How long should you keep an email address? Plan ahead.
Temporary test emails are available for 3 hours by default. What matters is when your email will arrive and whether you’ll need to access it again later. Adjust the options below for a recommendation tailored to your task.
Plan how long you’ll wait for this test
Quick test: Use a temporary email. Extend it before it expires if needed.
Work backward from when the email will arrive
Senders usually send verification codes right away, but the email may take time to arrive due to queues and filtering. A signup that takes just a few minutes can use a temporary address. For manual approval, support replies, or emails that may arrive days later, use an inbox or alias you control from the start.
The task isn’t finished yet
You can extend the address while it’s still active. First, make sure the inbox confirms the extension. Once an address expires and is deleted, it can’t be extended.
Need to receive emails tomorrow?
Switch to forwarding aliases to keep messages from different tests separate. When you’re done, pause the relevant alias for more control than relying on an expired temporary email.
What if my temporary email expires?
An expired address can’t receive new email, and old messages usually can’t be recovered. Restart the process with the sender and use a new address for the new code. If a third-party account is linked to the old address, first follow that service’s email-change or manual account recovery process.
If you can’t change the address linked to an account, don’t treat the same temporary address as a permanent account you can sign up for again. Use an inbox you control long-term for important updates. To keep sources separate, use the Alias vs. Temporary Email Decision Matrix to choose.
Plan your time before testing
| Scenario | Estimated duration | Recommendation |
|---|---|---|
| One-time signup code | A few minutes | Temporary email; discard it when testing is complete |
| Activation after manual approval | Hours to days | Check the expected wait; use a long-term alias if needed |
| Follow-up emails or support | Uncertain | Long-term alias you can pause separately when finished |
| Recovering an important account | Ongoing | Use an email address you control directly |
