Extend
Extend the current receiving window without changing the address—useful when a sender is delayed or a download is still processing.
Note: total time cannot exceed 24 hoursTemporary email lifetime
3 hours by default, up to 24 hours for one email task
This address is not a permanent account—it is a pickup pass with an expiry time. Use the countdown to plan for verification codes, downloads, and testing. For ongoing communication, switch to a forwarding alias.
Lifetime timeline
Know what to expect from creation to cleanup
Extensions add time to the current address but never push its total lifetime beyond 24 hours.
- 00:00
Address created
The page creates a random email address and access token. The countdown starts at 3 hours by default.
- Before expiry
Receive and extend
Copy the address, refresh the inbox, read or delete messages, and add time if you still need to wait.
- Up to 24h
Lifetime limit
No matter how many times you extend it, the same address never becomes a permanent mailbox.
- 00:00
Receiving stops
After expiry, access ends and the address and its contents enter the cleanup process. It cannot be used for account recovery.
What each action does
Extensions, new addresses, and deletion are different
Before choosing an action, decide whether you need more time, a fresh identity, or an immediate end to the current task.
Get a new address
Create a new email address with a fresh 3-hour window. The old address is destroyed immediately, keeping separate tasks apart.
Note: save anything important from the old inbox firstDelete
End the current mailbox and access token immediately instead of waiting for the countdown to finish.
Note: deletion cannot be undoneWhen to extend
Add time only to an active task
Verification codes usually do not require an extension. Large file generation, manual approval, or test batches may take more than 3 hours; extend the address before it expires. If the relationship will last for days, continuing to extend is not the right solution.
The sender has already taken action
The other party is generating a file or waiting to deliver it—you only need a little more time.
You are starting another task
Use a new, separate address for a new website, test, or download.
Follow-up will continue
Use a pausable long-term alias for support, subscriptions, or project notifications.
Before you leave
Save anything important before the countdown ends
A temporary email is valuable because it has a clear exit—not because it stores everything forever.
Take with you
- Files you genuinely need to download
- Reference numbers for legitimate transactions
- Non-sensitive instructions needed for follow-up
- A new receiving route for ongoing communication
Do not rely on it for
- Recovering a primary account password
- Financial or identity-verification credentials
- Ongoing medical or government communications
- The only copy of an important attachment
Frequently asked questions
Countdowns, extensions, and expiry
Understand the time limits so you do not mistake a one-time address for a long-term account.
Will closing the page immediately delete the mailbox?
Usually not. If your browser still has the access token, reopening the page can restore the current inbox before it expires. Clearing site data removes the local key.
Can an expired address be reactivated?
No. An expired address is not guaranteed to be assigned again, and old messages cannot be recovered. Create a new address for a new task.
Does switching addresses after an extension carry over the remaining time?
No. “Get a new address” creates a new mailbox with the default 3-hour lifetime and destroys the old one. Extra time does not carry over to the new task.
What if I still need to receive mail after 24 hours?
If the relationship will continue, log in and create a forwarding alias. For another short-term task, create a brand-new temporary address.
