Email terms · From concepts to action
What does disposable email mean? Start here: it’s an address for short-term email, not a new account you need to maintain.
A guide to the terms
These terms are often used interchangeably, but they’re not standardised technical definitions. To understand what a service does, check its expiry, deletion rules and forwarding options—not just its name.
Before signing up, consider whether you’ll need this address to recover your account later. Don’t rely on temporary email as your only contact method for anything you need to keep. See the sign-up checklist.
Glossary index
Browse by three stages of use. Each entry includes a definition, a practical example and a common misconception.
01 · Addresses and identity
You can give a sending website your email address, but never share the token that lets someone open your inbox. They’re not the same thing.
See the privacy boundaries →The complete address a sender uses to deliver email. It consists of a name before @ and a domain after it. Copy the entire address, not just the part before @. The address shown on the page is the one currently receiving email.
ExamplePaste the full address generated on the homepage into a suitable sign-up form, then return to the inbox and wait for the verification code.
Common misconception“If I know the address, I have the account.” An address is where email is delivered. It doesn’t grant inbox access or prove anyone’s real-world identity.
An access token lets your browser open the current temporary inbox. It’s stored separately from the email address and isn’t the login for a forwarding account. Clearing local browser data or switching devices may prevent you from accessing the original inbox.
ExampleWhen you return to the homepage in the same browser, it will try to use the locally saved token to restore your inbox if it’s still active.
Common misconception“It’s fine to send someone my page’s debug information.” It may contain an access token. Don’t share credentials, token-bearing requests or screenshots.
A forwarding address linked to your personal email. After logging in to FadeInbox, you can create aliases, check their status, and disable or delete them. When an alias is enabled, messages sent to it are forwarded to your personal email.
ExampleCreate an alias for shopping notifications. If you no longer want to receive them, disable the alias instead of changing your personal email address.
Common misconception“An alias is another email account that can send messages.” FadeInbox aliases receive and forward email; they can’t send email from the alias.
An email address you control long-term, used to receive sign-in codes and forwarded messages. Choose one you can keep accessing. Don’t use an expiring temporary address for a forwarding account you’ll need to log in to and receive email from.
ExampleLog in with your everyday email address, then have shopping notifications and subscription messages sent to different aliases forwarded there.
Common misconception“Personal” means you must provide your name or use an email address registered under your real name. Here, it means an inbox you control—not a requirement to identify yourself.
02 · Time and deletion
New temporary addresses last three hours by default. Extending keeps the current address; changing it ends the old inbox. These actions aren’t interchangeable.
See the full timeline →The period when a temporary address remains usable. New FadeInbox addresses last three hours by default. When an address expires, it stops working and its emails and attachments are deleted. Check the homepage countdown for the current expiry time.
ExampleAn address created at 14:00 is expected to expire at 17:00 if you don’t extend it. Emails received later expire along with the address.
Common misconception“Every new email gets its own three hours.” The expiry applies to the inbox. New messages don’t extend the address’s lifetime.
The time between now and the address’s expiry. The homepage countdown updates continuously. Closing the tab doesn’t pause the timer on the server, and reopening it doesn’t start a fresh period.
ExampleIf the page shows 20 minutes remaining but signing up may take longer, consider extending the address before it expires.
Common misconception“If I can see the address on an old page, it must still work.” If your connection drops or your device goes to sleep, reconnect and refresh to check.
Add three hours to the current address’s lifetime without changing the address or clearing existing messages. Select “Extend by 3 hours” in the homepage inbox, wait for confirmation, then check the countdown.
ExampleIf an extension succeeds with 20 minutes remaining, you’ll have about 3 hours and 20 minutes left—not a reset to three hours.
Common misconception“Refreshing the page extends the address.” Refreshing checks for email; extending requires a separate action and can’t restore a deleted inbox.
Switch to a newly generated temporary address, which starts a new three-hour period. The old address and its messages are deleted. Before switching, save anything you need and check that you aren’t still waiting for a code sent to the old address.
ExampleWhen one short-term task is finished and you’re ready to start another, switch addresses and paste the new one into the next form.
Common misconception“Messages sent to my old address will move to the new inbox.” Changing addresses isn’t a migration, and messages sent to the old address won’t be forwarded to the new one.
Ending a temporary inbox and removing its contents. An inbox is deleted automatically when it expires, or when you switch to a new address. Deleting one email removes only that message; it doesn’t make the address expire sooner.
ExampleIf you only want to remove a verification email, delete that message. You don’t need to change the address if you’re still waiting for other emails.
Common misconception“If FadeInbox deletes something, the sender’s records disappear too.” Deletion can’t remove third-party copies, saved files or records held by other services. See our Privacy Policy.
03 · Receiving email and security
Email verification codes, authenticator codes and authenticator secrets serve different purposes. Never share them with anyone, including someone who says they can help troubleshoot a problem.
No verification code? Troubleshoot →A short-lived code sent by a service to confirm an action. The sender decides how long it’s valid and how many times it can be used—not the temporary inbox’s three-hour lifetime. FadeInbox sign-in also uses a six-digit code sent to your personal email.
ExampleIf an email says a verification code is valid for 10 minutes, return to the original website and enter it within that time. Don’t wait until the address is about to expire.
Common misconception“Support needs my code to check delivery.” You can describe when the problem happened and what you saw, but don’t share verification codes or inbox credentials.
Delivering email sent to an enabled alias to the personal email linked to it. Unlike temporary messages displayed directly on the homepage, forwarding requires an account login. Delivery may still be affected by the recipient’s filtering rules or other issues.
ExampleA shopping site sends a notification to your alias, and you read it in your personal inbox without keeping the temporary inbox open.
Common misconception“Turning on forwarding extends the life of a temporary address.” Forwarding aliases and temporary inboxes are separate features. To choose between them, see Address comparison.
A 30-day archive of forwarded emails available in the dashboard after you log in. It’s separate from the temporary inbox on the homepage and isn’t a permanent backup. Save anything you need to keep elsewhere before it’s removed.
ExampleIn the dashboard, check a forwarded email’s subject, sender, status and contents to review recent delivery.
Common misconception“I can retrieve messages from the archive after a temporary address expires.” Temporary emails aren’t added to the forwarding archive, and the archive can’t restore an expired address.
A mobile app that generates time-based sign-in codes, such as Google Authenticator, Microsoft Authenticator or 1Password. To set it up, scan the QR code shown in the dashboard, then enter the six-digit code generated by the app. If you can’t scan the code, add it manually using the key provided on the page.
ExampleAdd FadeInbox to your authenticator app, then enter the current six-digit code in the dashboard to confirm and enable it.
Common misconception“A QR code is just an image, so it’s safe to share.” It contains the secret key used to generate codes. Never share the QR code, key or authenticator code.
An extra sign-in check that asks for an authenticator code after the email verification code. Set up and enable an authenticator app first; future sign-ins will then require this extra step. Make sure you can securely back up your authenticator and move it to a new device.
ExampleAfter entering the sign-in code from your email, enter the current six-digit code from your authenticator app. You must pass both checks to access the dashboard.
Common misconception“Enabling this means I also need an account to use a temporary inbox.” Two-step verification protects your forwarding account. It doesn’t change how you access temporary email on the homepage without signing up.
Terms people often mix up
When two terms sound alike, ask what each one affects: identity, email delivery or how long content is kept.
Anonymity This is about whether your activity can be linked to an identity. No sign-up doesn’t mean you can’t be identified by any of the parties involved.
Privacy This is about how data is collected, used and retained. Hiding your everyday email can reduce direct exposure, but it doesn’t guarantee complete anonymity.
Review how your data is handled →Delete What gets deleted depends on the item: deleting an email removes its contents, while deleting an alias removes the forwarding address. Don’t treat an irreversible action like a temporary switch.
Disable Keep the alias but stop forwarding email. Messages sent while it’s disabled are discarded; enabling it again won’t recover them.
Learn how to manage each address type →Temporary inbox No login required: read email on the website, then the address and messages are deleted when it expires. Best for short-term tasks that don’t depend on future messages.
Ongoing forwarding Log in to manage aliases and receive messages in your personal inbox. “Ongoing” doesn’t mean permanent storage or a guarantee that the service will never change.
Manage email forwarding →Keep reading by topic
You don’t need to memorise every term. Find the instructions for the task you’re working on.
Check the current expiry, what changes when you extend it, and what to save before switching addresses.
View the expiry guide → DeliveryCheck the address first, then review the wait time and sender’s restrictions to avoid requesting the code repeatedly.
Troubleshoot delivery → ChoosingFirst consider whether you’ll need account recovery, ongoing notifications or important credentials. Then choose the right type of address.
Read the sign-up checklist →Go to the homepage to get a temporary email address. Copy the full address and keep an eye on the countdown. Use an email address you control long-term for important accounts, bills and future account recovery.
