QUICK START
Complete guide: from creating a disposable email to reading messages
No signup or password required. Copy the current address to the target site, wait for the verification code there, then decide whether to extend or discard the address.
BEFORE YOU START
Decide whether you’ll need to recover this account later
Disposable email works best for short-term, low-risk signups that don’t need recovery. For accounts with purchase history, work content, or a lasting identity, use a forwarding alias or your regular email instead.
Up to 24 hours
Extend by 3 hours at a time if you still need to finish the task.

WORKFLOW
Five actions, each for a different step
Don’t keep changing the address while waiting for an email. Switching addresses invalidates the old address in the signup form, and later messages won’t be moved over.
1. Copy the addressClick Copy, paste the complete address into the signup form, and make sure it contains no spaces.
2. Submit the signupWait for the target site to clearly show “Sent” or a similar confirmation.
3. Refresh the inboxYou can refresh once manually in addition to automatic polling; messages usually arrive within two minutes.
4. Open the emailClick the row to read the message and use the verification code with the latest timestamp.
5. Extend or replace the addressExtend the address if the same task isn’t finished; replace it only when starting a new task.
READING TIPS
Verification codes, confirmation links, and mobile reading
Verification emails may invalidate older codes after multiple sends, so check the latest timestamp. Confirmation links may be tied to the browser session where signup began, so open them on the same device.
On mobile, tapping an email opens a full-screen reader; close it to return to the list. Real HTML emails appear in an isolated frame and cannot directly alter the site page.
Not receiving an email?
Check the address, confirm that the site sent the message, wait two minutes, and refresh once. If the site explicitly rejects temporary domains, respect the restriction and use a long-term email instead.
ACTION COMPARISON
Extending an address isn’t the same as replacing it
| Action | Does the address change? | Are messages kept? | When to use it |
|---|---|---|---|
| Refresh | No change | Kept | Check for new messages |
| Extend by 3 hours | No change | Kept | The current task isn’t finished |
| Replace address | Changes immediately | Old inbox is closed | Start a completely new signup task |
| Reload the page | Restore while still valid | Kept | Continue after accidentally closing the page |
FAQ
The points that most often confuse first-time users
Do I need to sign up for MaskSend first?
The temporary inbox requires no signup. Only long-term forwarding aliases require you to log in with a verification code sent to your destination email.
Will refreshing my browser change the address?
While it’s still valid, the address will be restored in your current browser. It changes only when you click Replace address or when it expires.
Can I reply to emails?
No. A disposable email is a short-term, receive-only inbox and does not provide a sending identity.
When must I use a regular email address?
Use a trusted long-term email for banking, healthcare, government, work, and any account where losing recovery access would be unacceptable.
