Keep your real address private
Sign-up forms, trial pages, and unfamiliar download sites see only a temporary identity. Reduce the entry points that can lead to marketing lists, data matching, and later credential-stuffing attempts.

Less exposure
Keep one-time sign-ups separate from your long-term identity
Many websites need only one confirmation, yet ask for a real email address that can be tracked for years. A disposable address limits that exposure to the task at hand: receive a code, confirm your account, then let the address expire naturally.
Verification codes appear right here
The inbox checks for new mail automatically and also supports manual refresh. Open a message to read its code or confirmation link without switching between tabs.
A clear, visible time limit
Each new email lasts 3 hours by default, with a countdown always visible. Extend it while your task is unfinished, up to 24 hours in total.
Choose the right identity
Temporary email or forwarding alias? Start with how long the relationship will last
A temporary email works for completing a one-time verification quickly. A forwarding alias is better for an account you may need to recover, receive bills for, or maintain over time. Both hide your real address, but they serve different purposes.
If the account may still matter later, don’t use an address that will expire. MaskSend’s permanent forwarding option handles logins, aliases, and 30-day archives separately, without duplicating a second dashboard on the home page.
Only receiving one verification codeUse the temporary email here, then let the address expire.
You may need to recover the accountUse a forwarding alias to deliver future messages to your real inbox.
Testing a multi-step sign-up flowChange the temporary address so test data stays out of your personal inbox.
Payment, medical, or identity documents involvedUse a trusted long-term email instead of relying on a temporary address.
Three simple steps
From copying the address to reading your verification code
The tool area requires no registration and never asks for your real email first. Once generated, the address can receive mail immediately, with the list and message view in one workspace.
Copy the current address
Click “Copy address” and paste the complete disposable email into the sign-up form you need to verify. When you refresh the page, an active address is restored from this browser instead of being replaced.
Return to the inbox and wait
When mail arrives, it replaces the demo messages. New mail stays unread until you open it, so its status is not cleared automatically.
Read the message and confirm
View the message in the reading pane on the right; on mobile, it opens in a full-screen reader. Verification codes, confirmation links, and sender details are shown in full.
Delivery diagnostics
No verification email yet? That doesn’t mean the inbox is broken
Most delays come from the sender’s queue, a mistyped address, or a website blocking temporary domains. Refresh manually and check the address before deciding whether to try again with a new one.
Don’t trigger a dozen sends in a row: many sites will impose a cooldown or keep only the latest code. Wait two minutes, check the sender page for guidance, then continue.
01Check the email address character by character, especially for spaces accidentally included during copying.
02Refresh once and wait for the sender to finish delivery; the newest message usually contains the valid code.
03If it still hasn’t arrived, change the address. If the site explicitly blocks temporary email, use a forwarding alias or a long-term email instead.
Safety boundaries
Convenient doesn’t mean suitable for every email
A temporary email reduces exposure; it is not a secure vault for long-term accounts. Understand the limits around expiration, attachments, and account recovery before using it as a privacy tool.
| Use case | Recommendation | Why |
|---|---|---|
| Forums, trials, one-time downloads | Temporary email is suitable | Only short-term verification is needed and later messages have little value. |
| Social or developer accounts you’ll keep using | Prefer a forwarding alias | Keep a reliable path for password resets and security alerts. |
| Banking, healthcare, government, and identity services | Use a trusted long-term email | These accounts need a stable identity, audit history, and lasting recovery access. |
| Messages with important attachments | Don’t rely on a temporary inbox | Temporary email does not retain attachments, and messages over 100MB are rejected. |
Key concepts
What’s the difference between temporary, disposable, and anonymous email?
These search terms often refer to the same type of short-term inbox, but each highlights something different. “Temporary email” emphasizes limited availability, “disposable email” emphasizes abandoning it after one task, and “anonymous email” emphasizes keeping the address separate from your real identity.
This MaskSend page provides a disposable inbox with a clear countdown. Registration is not required, but websites may still record browser, network, or sign-up activity—sharing less personal information does not make online activity completely anonymous.
The rule of thumb to remember
If you might need to recover the account later, don’t rely on an address that will expire. If an email involves sensitive identity details or long-term credentials, choose an address you control continuously.
Disposable email is best for isolating low-trust, short-lived sign-ups—not for replacing all personal communication.
Frequently asked questions
What to know before using a disposable email address
Find answers about expiration, verification codes, address recovery, and privacy boundaries. Expand an answer without leaving the current inbox.
How long can I use a disposable email?
New addresses last 3 hours by default. You can extend them by 3 hours at a time while your task is unfinished, but each mailbox exists for a maximum of 24 hours from creation.
Will my address change when I refresh the page?
No. As long as the address is still active, MaskSend restores the same mailbox from your current browser. A new address is created and the old one discarded only when you click “Change address.”
Can a temporary email receive verification codes?
Yes, it can receive common verification codes and confirmation links. Some websites block temporary email domains themselves; that restriction comes from the sending site, not an inbox failure.
Why is my verification email delayed?
Check the address and refresh manually, then wait one or two minutes. If the sender shows a rate limit, don’t resend repeatedly; try a new address or forwarding alias if nothing arrives.
Can I use it to register an important account?
We don’t recommend it. Once a temporary address expires, it cannot be used for password recovery. For payment, work, healthcare, or long-term accounts, use a lasting email or a forwarding alias you can keep controlling.
Does the temporary inbox retain attachments?
No. Attachments are not retained, and messages over 100MB are rejected. If you need to receive files over time, choose a long-term email or a MaskSend forwarding alias.
